Description

[Technical field]

[0001] The present invention relates to a solid target handling system. [Background technology]

[0002] A conventional solid target handling system is described in Patent Document 1. In this solid target handling system, a solid target is held by a target device at the position of the particle beam emission port. When the target material of the solid target is being irradiated with the particle beam, the target device supplies cooling water to the solid target to cool it. When the irradiation of the solid target with the particle beam is completed, the target device releases the holding and drops the solid target to be placed into a receiving member. As a result, the solid target placed into the receiving member is transported to a recovery section while rolling through a transport duct. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2013-167489 A Summary of the Invention [Problem to be solved by the invention]

[0004] As described above, cooling water adheres to the solid target during cooling. Such cooling water may remain on the surface of the solid target even during transport in the transport duct. Therefore, problems such as the solid target sticking to the transport duct or a decrease in transport speed may occur due to the adhered moisture.

[0005] Therefore, an object of the present invention is to provide a solid target handling system capable of improving the reliability of transporting a solid target after irradiation with a particle beam. [Means for solving the problem]

[0006] A solid target handling system according to one aspect of the present invention is a solid target handling system that handles a solid target having a target material that is irradiated with a particle beam, and includes a holding unit capable of holding the solid target after irradiating it with the particle beam, and a moving mechanism capable of moving the holding unit while holding the solid target.

[0007] The solid target handling system includes a holding unit capable of holding the solid target after irradiation with a particle beam. Furthermore, the solid target handling system includes a moving mechanism capable of moving the holding unit while holding the solid target. Therefore, the moving mechanism can move the held solid target at the same time by moving the holding unit. In this case, since the solid target moves while being held by the holding unit, problems such as moisture remaining on the solid target sticking to the transport path or a decrease in transport speed do not occur. As a result, the reliability of transport of the solid target after irradiation with a particle beam can be improved.

[0008] The holder may include a guide mechanism for guiding the solid target into and out of the holding position of the holder. In this case, when the solid target is introduced into the holder, it can be guided to the holding position with high precision. Furthermore, when the solid target is transferred from the holder to a destination container, it can be transferred with high precision by the guide mechanism.

[0009] The holding unit may include an opening / closing mechanism, and the opening / closing mechanism may be switchable between an open state that allows the solid target to be loaded into the holding unit and a closed state that allows the solid target loaded into the holding unit to be held in a state in which it is accommodated within the holding unit. In this case, the holding unit can receive the solid target in the open state, and transport the solid target to a destination in a state in which the solid target is accommodated inside the holding unit in the closed state. When the holding unit accommodates and transports the solid target inside in this way, it is easier to hold the solid target than when the pressing force is controlled to sandwich the solid target and transport it.

[0010] The holder may include a support mechanism having a support surface and supporting a portion of the solid target by pressing with the support surface. In this case, the holder can hold the solid target in a state in which rattling of the solid target is suppressed. When rattling is suppressed in this manner, it is possible to suppress the target material of the solid target from contacting the wall surface of the holder.

[0011] The support surface may support a portion of the solid target other than the target material, in which case contamination due to peeling of the target material can be suppressed.

[0012] The support surface may have a recess for avoiding contact with the target material. In this case, contact between the target material and the support surface can be easily suppressed by simply forming the recess in the support surface.

[0013] The moving mechanism may move the solid target by rotating a holder that holds the solid target. Since the vertical movement and rotation of the holder can be completed in a single operation, the solid target can be moved with a small number of parts, and malfunctions in the operation of the equipment can be reduced.

[0014] The moving mechanism may move the solid target by sliding the holder that holds the solid target. In this case, the moving mechanism can move the holder by linear movement. Therefore, the moving mechanism can be configured compactly.

[0015] The moving mechanism may be constituted by a robot arm. In this case, the moving mechanism is capable of moving the holder with complex movements. Effect of the Invention

[0016] According to the present invention, it is possible to provide a solid target handling system capable of improving the reliability of transporting a solid target after irradiation with a particle beam. [Brief description of the drawings]

[Figure 6] 13 is a schematic view showing a holding portion according to a modified example. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Various embodiments will be described in detail below with reference to the drawings. Note that the same or corresponding parts in each drawing are denoted by the same reference numerals, and duplicated explanations will be omitted.

[0019] 1 and 2 are schematic diagrams of a solid target handling system 100 according to an embodiment of the present invention. The solid target handling system 100 is a system that handles a solid target 50 having a target material to be irradiated with a particle beam B. As shown in FIG. 1 and FIG. 2, the solid target handling system 100 includes a target device 2, a chute unit 3, a holder 4, a moving mechanism 6, and a receiver 7. Each of the figures shows a first direction D1, which is a horizontal direction parallel to the irradiation direction of the particle beam B. Each of the figures also shows a second direction D2, which is a horizontal direction perpendicular to the first direction D1.

[0020] The target device 2 is a device for irradiating the particle beam B while holding the solid target 50. The target device 2 is attached to the outlet 10a of the accelerator 10 via a manifold 11 that emits the particle beam B. The target device 2 holds the solid target 50 at the position of the outlet of the outlet 10a. The solid target 50 held by the target device 2 is irradiated with the particle beam B at the position of the target material. When the solid target 50 is irradiated with the particle beam B, the target device 2 cools the solid target 50 by supplying cooling water to the back side of the irradiation surface. When the irradiation of the particle beam B to the solid target 50 is completed, the target device 2 releases the holding of the solid target 50 and drops it into the chute section 3. Note that a known device may be adopted as the target device 2, and the specific configuration of the target device 2 is not particularly limited.

[0021] As the material of the solid target 50, a material that is not dissolved by the dissolving liquid is adopted, such as Au, Pt, etc. As shown in FIG. 3(a), the solid target 50 is formed in a disk shape, but the shape and thickness are not particularly limited. As the target material 51, for example, 64 Ni, 89 Y, 100 Mo, 89 YO2, etc. Radioisotopes generated corresponding to the target material 51 include: 64 Cu, 89 Zr, 99m The target material 51 is formed in a layer shape by plating or the like at the center position of one main surface of the solid target 50. The particles of the irradiated particle beam B are, for example, protons, deuterons, alpha particles, or 3 He, etc.

[0022] As shown in Figs. 1 and 2, the chute unit 3 is a mechanism disposed below the target device 2. The chute unit 3 receives the solid target 50 that has been released from the target device 2 and dropped. For example, the chute unit 3 may be configured to easily receive the solid target 50 by widening the upper receiving opening and providing a taper or the like. The chute unit 3 also drops the solid target 50 inside according to a drop path so as to control the drop position of the solid target 50. The chute unit 3 drops the solid target 50 onto the holder 4 disposed below. The chute unit 3 is supported by a wall 16 of the accelerator 10 via a support member 14 (see Fig. 1).

[0023] The holding unit 4 is a member capable of holding the solid target 50 after irradiation with the particle beam B. The holding unit 4 receives the solid target 50 that has fallen from the chute unit 3. The holding unit 4 holds the received solid target 50. The state in which the solid target 50 is held is a state in which the entire solid target 50 is restricted from moving to a position away from the holding unit 4 in a state in which it is protruding from the holding unit 4, regardless of whether the holding unit 4 is turned sideways or downward. Even if a part of the solid target 50 protrudes from the area of ​​the holding unit 4, a state in which the other part is caught by the holding unit 4 and restricted from protruding any further corresponds to a state in which the solid target 50 is held. At this time, it can be said that the solid target 50 is held in a state in which it remains within the holding unit 4 or in the vicinity of the holding unit 4. The holding unit 4 can release the holding of the solid target 50 when transferring the solid target 50 to the receiving unit 7. The specific configuration of the holding unit 4 will be described later.

[0024] The moving mechanism 6 is a mechanism capable of moving the holding unit 4 in a state in which the solid target 50 is being held. The moving mechanism 6 moves the holding unit 4, which has received the solid target 50 in the chute unit 3, to the position of the receiving unit 7. In this embodiment, the receiving unit 7 is provided at a position below the target device 2 and the chute unit 3. Therefore, when the holding unit 4 receives the solid target 50 directly below the chute unit 3, the moving mechanism 6 moves the holding unit 4 downward from that position. Then, when the moving mechanism 6 moves the holding unit 4 to the position of the receiving unit 7, it stops the holding unit 4 at that position. Then, the holding unit 4 releases its hold and transfers the solid target 50 to the receiving unit 7.

[0025] In this embodiment, the moving mechanism 6 moves the solid target 50 by rotating the holding unit 4 that holds the solid target 50. Specifically, the moving mechanism 6 includes a rotating shaft unit 21, an arm unit 22, and a support unit 23. The rotating shaft unit 21 is a member that rotates the holding unit 4 via the arm unit 22. The rotating shaft unit 21 is disposed at a substantially middle position in the up-down direction between the chute unit 3 and the receiving unit 7. At this position, the rotating shaft unit 21 is disposed so as to be rotatable around a center line CL1. The support unit 23 rotatably supports the rotating shaft unit 21 at this position. The rotating shaft unit 21 is supported by the wall unit 16 of the accelerator 10 via the support unit 23 (see FIG. 1). The center line CL1 is set to extend parallel to the second direction. The arm unit 22 extends from the rotating shaft unit 21 to the outer periphery side and is connected to the holding unit 4. When the holding unit 4 is disposed directly below the chute unit 3, the arm unit 22 is in a state of extending in the vertical direction. In addition, a lower end of the arm unit 22 is connected to the rotating shaft unit 21, and an upper end of the arm unit 22 is connected to the holding unit 4. As the rotating shaft unit 21 rotates, the arm unit 22 revolves around the center line CL1 together with the holding unit 4. As a result, the holding unit 4 revolves on the revolving path RL.

[0026] The receiving unit 7 is a mechanism for receiving the solid target 50 after irradiation with the particle beam B from the holding unit 4 that has moved to the receiving position. The receiving unit 7 includes a container 26 and a rail unit 27. The container 26 is a member that receives the solid target 50 from the holding unit 4 and contains the received solid target 50. Since the solid target 50 after irradiation with the particle beam B is radioactive, the container 26 can contain the solid target 50 with a shielding member such as a thick lead wall. The container 26 may also have an openable lid unit 25. The container 26 waits at the receiving position RP (see FIG. 2) with the lid unit 25 open. When the holding unit 4 reaches directly above the container 26, the holding unit 4 releases its hold, and the solid target 50 falls into the container 26. The container 26 may include a stand mechanism or the like made of a soft material such as a sponge so that the received solid target 50 is not damaged. Such a stand mechanism can accommodate the solid target 50 that has dropped from the holder 4 in an upright position. The rail portion 27 is a mechanism for transporting the container 26 that has received the solid target 50. The rail portion 27 extends in a second direction from the receiving position RP (see FIG. 2). The rail portion 27 is provided on a floor portion 29. The container 26 is movable along the rail portion 27 via a slide portion 28. Note that the direction in which the rail portion 27 extends, i.e., the direction in which the container 26 moves, is not limited to the second direction, and the container 26 may be movable in another direction.

[0027] Next, the configuration of the holding unit 4 will be described in detail with reference to Figs. 3 and 4. Figs. 3(a) and 3(b) are cross-sectional views of the holding unit 4 as viewed from a first direction D1. Fig. 3(a) shows a state immediately after the holding unit 4 receives the solid target 50 from the chute unit 3. Fig. 3(b) shows a state immediately before the holding unit 4 transfers the solid target 50 to the receiving unit 7. Figs. 4(a) and 4(b) are cross-sectional views of the holding unit 4 as viewed from a second direction D2. Fig. 4(a) shows a state immediately after the holding unit 4 receives the solid target 50 from the chute unit 3. Fig. 4(b) shows a state in which the holding unit 4 holds the solid target 50. In this description, unless otherwise noted, the terms "upper" and "lower" will be used with reference to the states of Figs. 3(a) and 4(a).

[0028] As shown in FIGS. 3 and 4, the holding portion 4 includes a guide mechanism 30, a receiving member 35, and an opening / closing mechanism 40.

[0029] The guide mechanism 30 is a mechanism that guides the insertion and removal of the solid target 50 into and from the holding position of the holding unit 4. The guide mechanism 30 includes guide members 31A and 31B. The guide members 31A and 31B are disposed to face each other in the second direction. The guide members 31A and 31B have a configuration that is symmetrical with respect to the center line CL2 when viewed from the first direction D1 (see FIG. 3(a)). The guide member 31B has a configuration that is symmetrical with respect to the center line CL2 when viewed from the second direction D2 (see FIG. 4(a)). Although not shown in FIG. 4(a), the guide member 31A also has a configuration that is symmetrical with respect to the center line CL2 when viewed from the second direction D2.

[0030] As shown in FIG. 3(a), the guide members 31A and 31B extend upward from both ends of the base member 36 of the holder 4 in the second direction. The guide members 31A and 31B each have a guide surface 31a extending vertically so as to face each other in the second direction. The guide surface 31a of the guide member 31A and the guide surface 31a of the guide member 31B are set at a distance so as to form a gap slightly larger than the diameter of the solid target 50. As a result, the guide surfaces 31a of the guide members 31A and 31B guide the solid target 50 to fall from the chute unit 3 to the holding position and to fall from the holding position to the receiving unit 7. The guide surfaces 31a of the guide members 31A and 31B also regulate rattling in the second direction D2. A tapered surface 31b that widens toward the tip side is formed at the tip portion of the guide surface 31a of the guide members 31A and 31B, respectively. This allows the tapered surface 31b of the guide members 31A and 31B to receive the solid target 50 that has fallen from the chute section 3 and guide it to the holding position.

[0031] The guide members 31A and 31B are provided with a pair of guide walls 32 that sandwich the guide surface 31a and the tapered surface 31b from both sides in the first direction D1 (see also FIG. 4(a)). The pair of guide walls 32 of the guide members 31A and 31B can guide the solid target 50 by sandwiching the vicinity of both ends in the second direction D2. The pair of guide walls 32 of the guide members 31A and 31B have a guide surface 32a and a tapered surface 32b. The pair of guide surfaces 32a of the guide members 31A and 31B are set to a distance away from each other so as to form a gap larger than the thickness of the solid target 50. As a result, the guide surfaces 32a of the guide members 31A and 31B guide the solid target 50 to fall from the chute unit 3 to the holding position and to fall from the holding position to the receiving unit 7. In addition, the pair of guide surfaces 32a of the guide members 31A and 31B prevent the guide members 31A and 31B from falling in the first direction D1. The pair of tapered surfaces 32b of the guide members 31A and 31B can receive the solid target 50 that has fallen from the chute portion 3 and guide it to the holding position.

[0032] 3(a), a receiving member 35 is provided so as to span between the guide members 31B and 31B. The receiving member 35 is adapted to place the vicinity of the lower end of the solid target 50 placed at the holding position. The receiving member 35 has a receiving surface 35a that curves along the outer circumferential surface of the solid target 50. The height position of the receiving member 35 is not particularly limited, but may be any height such that when the solid target 50 is placed on the receiving surface 35a, the upper end of the solid target 50 is positioned lower than the upper ends of the guide members 31A and 31B and the opening / closing members 41A and 41B described below.

[0033] As shown in FIG. 4(a), the opening / closing mechanism 40 includes opening / closing members 41A and 41B. The opening / closing members 41A and 41B are disposed so as to face each other in the first direction D1. The opening / closing members 41A and 41B have a configuration that is symmetrical with respect to the center line CL2 when viewed from the second direction D2 (see FIG. 4(a)). The opening / closing member 41A has a configuration that is symmetrical with respect to the center line CL2 when viewed from the first direction D1 (see FIG. 3(a)). Although not shown in FIG. 3(a), the opening / closing member 41B also has a configuration that is symmetrical with respect to the center line CL2 when viewed from the first direction D1.

[0034] As shown in FIG. 4(a), the opening / closing members 41A and 41B are provided on both ends of the base member 36 in the first direction. The opening / closing members 41A and 41B have an L-shape when viewed from the second direction D2, and include a main body portion 42 and a slide portion 43. The main body portion 42 rises upward from the base member 36. The base member 36 of the opening / closing member 41A and the base member 36 of the opening / closing member 41B face each other in the first direction D1. The slide portion 43 is provided at the lower end of the main body portion 42. The slide portion 43 has a slider 43a, and can be moved back and forth along a guide portion 44 provided on the base member 36 by the slider 43a. Since the guide portion 44 extends in the first direction, the opening / closing members 41A and 41B can be moved back and forth in the first direction D1. The opening / closing members 41A and 41B are given a driving force by a driving unit not shown. As the driving unit, an air supply mechanism or the like is adopted. However, the type of the driving unit is not particularly limited, and driving may be performed using a known method such as an air supply mechanism or a motor.

[0035] The main body 42 of the opening / closing member 41A and the main body 42 of the opening / closing member 41B each have opposing surfaces 42a that face each other with the solid target 50 arranged at the holding position in between. A protruding wall portion 46 that protrudes in a first direction D1 toward the center line CL2 is formed at the upper end of the opposing surfaces 42a of the opening / closing members 41A and 41B. When the opening / closing members 41A and 41B move toward the center line CL2, the protruding wall portions 46 of the opening / closing members 41A and 41B come into contact with each other as shown in FIG. 4(b). At this time, the opposing surface 42a of the opening / closing member 41A and the opposing surface 42a of the opening / closing member 41B are arranged at positions that leave a gap with the solid target 50. In this state, the solid target 50 is accommodated in a space between the opposing surface 42a of the opening / closing member 41A and the opposing surface 42a of the opening / closing member 41B, and cannot come out of the space due to the blocked protruding wall portion 46. In this state, the solid target 50 is held by the holder 4 and is prevented from coming out of the holder 4 even during movement by the movement mechanism 6 .

[0036] With the above-mentioned configuration, the opening / closing mechanism 40 can be switched between an open state shown in FIG. 4(a) and a closed state shown in FIG. 4(b). In the open state shown in FIG. 4(a), the protruding wall portions 46 of the opening / closing members 41A and 41B are spaced apart with a gap therebetween, so that the solid target 50 can be thrown into the holder 4. In the closed state shown in FIG. 4(b), the solid target 50 thrown into the holder 4 can be held in a state of being accommodated within the holder 4. Also, as shown in FIG. 3(b), when the open state is set in a state where the protruding wall portions 46 are arranged on the lower side, the solid target 50 falls from the gap between the pair of protruding wall portions 46.

[0037] Next, the actions and effects of the solid target handling system 100 according to this embodiment will be described.

[0038] The solid target handling system 100 includes a holder 4 capable of holding the solid target 50 after irradiation with the particle beam B. The solid target handling system 100 further includes a moving mechanism 6 capable of moving the holder 4 while holding the solid target 50. Therefore, the moving mechanism 6 can simultaneously move the held solid target 50 by moving the holder 4. In this case, since the solid target 50 moves while being held by the holder 4, problems such as moisture remaining on the solid target 50 sticking to the transport path or a decrease in transport speed do not occur. As a result, the reliability of transport of the solid target 50 after irradiation with the particle beam B can be improved.

[0039] The holder 4 may include a guide mechanism 30 that guides the solid target 50 when it is put into or taken out of the holding position of the holder 4. In this case, when the solid target 50 is put into the holder 4, it can be guided to the holding position with high precision. Furthermore, when the solid target 50 is transferred from the holder 4 to the container 26 as the transfer destination, it can be transferred with high precision by the guide mechanism 30.

[0040] The holding unit 4 includes an opening / closing mechanism 40, which may be switchable between an open state that allows the solid target 50 to be loaded into the holding unit 4 and a closed state that allows the solid target 50 loaded into the holding unit 4 to be held in a state in which it is accommodated within the holding unit 4. In this case, the holding unit 4 can receive the solid target 50 in the open state, and transport the solid target 50 to a destination in a state in which the solid target 50 is accommodated inside the holding unit 4 in the closed state. When the holding unit 4 accommodates and transports the solid target 50 inside in this way, it is easier to hold the solid target 50 than when the solid target 50 is sandwiched and transported while controlling the pressing force.

[0041] The moving mechanism 6 may move the solid target 50 by rotating the holder 4 holding the solid target 50. Since the vertical movement of the holder 4 and the rotation of the holder 4 can be completed in a single operation, the solid target 50 can be moved with a small number of parts, and malfunctions in the operation of the equipment can be reduced.

[0042] The present invention is not limited to the above-described embodiments.

[0043] For example, the specific configuration of the moving mechanism 6 is not limited to the above embodiment. For example, as shown in FIG. 5(a), the moving mechanism 6 may move the holding unit 4 holding the solid target 50 by sliding it. In this case, the moving mechanism 6 can move the holding unit 4 by linear movement. Therefore, the moving mechanism 6 can be configured compactly. For example, as shown in FIG. 5(a), the moving mechanism 6 includes a rotary actuator 61 that rotatably supports the holding unit 4, and a rodless cylinder 62 that slides and moves the holding unit 4 together with the rotary actuator 61. In this case, the holding unit 4 that receives the solid target 50 at the upper end position of the rodless cylinder 62 is moved downward by the rodless cylinder 62. At the lower end position, the holding unit 4 is rotated by the rotary actuator 61, and can drop the solid target 50 downward.

[0044] 5(b), the moving mechanism 6 may be configured by a robot arm 70. In this case, the moving mechanism 6 can move the holder 4 with complex movements.

[0045] The configuration of the holding unit 4 is not limited to this embodiment. For example, the holding unit 4 may be one shown in FIG. 6. For example, the holding unit 4 in FIG. 6(a) may include a support mechanism 80 having a support surface 81a and supporting a part of the solid target 50 by pressing the support surface 81a. The support mechanism 80 includes support members 81 provided on the opening / closing members 41A and 41B. The support member 81 has a support surface 81a that supports the solid target 50 by pressing the solid target 50. A recess 82 for avoiding the target material 51 is formed on the support surface 81a. Therefore, the support surface 81a supports a part of the outer periphery of the solid target 50 that surrounds the target material 51. A seal member such as an O-ring is disposed on the support surface 81a.

[0046] Also, a support mechanism 90 in Fig. 6(b) may be employed. In the support mechanism 90, a support member 81 on one side presses the solid target 50 against a receiving wall portion 91, thereby holding the solid target 50. A recess 92 is formed in a supporting surface 91a of the receiving wall portion 91 at a location corresponding to the target material 51. The receiving wall portion 91 may be a wall portion of a guide member 130 of the guide mechanism 30 that guides the solid target 50. The guide member 130 is formed by connecting the guide wall portion 32 of the guide member 31A and the guide wall portion 32 of the guide member 31B in Fig. 3(a) to each other.

[0047] 6(a) and 6(b), the holder 4 may be provided with support mechanisms 80, 90 that support a portion of the solid target 50 by pressing with the support surfaces 81a, 91a. The holder 4 can hold the solid target 50 in a state in which the movement of the solid target 50 relative to the wall surface of the holder 4 and rattle is suppressed. When rattle is suppressed in this manner, the target material 51 of the solid target 50 can be prevented from contacting the wall surface of the holder 4 and the like.

[0048] The support surfaces 81a and 91a may support portions of the solid target 50 other than the target material 51. In this case, contamination caused by peeling of the target material 51 can be suppressed.

[0049] The support surfaces 81a, 91a may have recesses 82, 92 for avoiding contact with the target material 51. In this case, simply by forming the recesses 82, 92 in the support surfaces 81a, 91a, it is possible to easily prevent contact between the target material 51 and the support surfaces 81a, 91a.
