It includes a sample base, on which a mechanical stretching module, a mechanical compression and TEM module, an irradiation injection module and an irradiation angle module are sequentially arranged in a field shape. The device improves the utilization efficiency of the accelerator beam. The sample holder of the device can provide irradiation of multiple samples at a time, saving irradiation experiment time and sample consumption. The present invention organically combines conventional mechanical experiment samples, TEM samples, and samples with varying irradiation conditions, and can obtain a large amount of irradiation sample data at one time, avoiding the difference in material irradiation damage caused by unstable accelerator beam state due to the same parameter adjustment setting, and the results are more consistent.

[0003] However, the above-mentioned device still has obvious defects during use: although the above-mentioned device can adjust the irradiation angle, it cannot adjust the irradiation angle independently.

Since metals such as tungsten steel will generate heat during the irradiation process, the concentration of heat will be not conducive to the normal irradiation, and will cause damage to the irradiation device and the sample, which will be not conducive to the normal development of subsequent operations.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-5 , the present invention provides a technical solution: Embodiment 1: A modular particle accelerator material irradiation sample fixing device comprises a sample base 1, a sample loading seat 2 is fixedly mounted on the sample base 1, a flip loading slot 3, a circular loading slot 4 and a rectangular loading slot 5 are arranged in pairs on the sample loading seat 2, a flip frame 7 is fixedly mounted in the flip loading slot 3 through a hollow rotating shaft 6, a modular frame bar 8 is detachably mounted on the flip frame 7, and the modular frame bar 8 comprises a rectangular modular frame bar 9 and a circular modular frame bar 10; A plurality of water-cooled liquid storage tanks 11 are provided in the sample base 1 and the sample loading seat 2. The water-cooled liquid storage tanks 11 are arranged near the flip loading slot 3, the circular loading slot 4 and the rectangular loading slot 5. The water-cooled liquid storage tanks 11 are also connected to the liquid inlet pipe 12 and the liquid outlet pipe 13 through the through holes provided on the side of the sample base 1. The liquid inlet pipe 12 and the liquid outlet pipe 13 are connected to an external water-cooled circulation device, and the cooling medium circulates in the water-cooled liquid storage tank 11 through the external water-cooled circulation device. The turning frame 7 is driven by the turning mechanism to perform a turning motion of 0-180°, thereby adjusting the irradiation angle and irradiation surface of the sample.

[0017] In this embodiment, the sample base 1 and the sample loading seat 2 serve as the main structure of the device, and are provided with a flip loading slot 3, a circular loading slot 4 and a rectangular loading slot 5, wherein the circular loading slot 4 and the rectangular loading slot 5 are used for loading fixed samples, a flip frame 7 is fixedly rotatably mounted on the flip loading slot 3, and a modular frame bar 8 is detachably mounted on the flip frame 7, wherein the modular frame bar 8 includes a rectangular modular frame bar 9 and a circular modular frame bar 10, and the corresponding modular frame bar 8 can be selected according to the shape of the sample, and the modular frame bar 8 is a two-sided through structure, and the frame of the modular frame bar 8 is connected to the sample. The sample is clamped and fixed, and the flip frame 7 changes the irradiation angle and irradiation surface of the sample by flipping, so that the sample can be irradiated more comprehensively. In addition, the existing tungsten, steel and other structures will generate heat during the irradiation process. If the heat is not evacuated in time, it will cause damage to the irradiation device and the sample, which will be detrimental to the normal development of subsequent operations. For this reason, in this embodiment, a water-cooled liquid storage tank 11 is further opened in the sample loading seat 2, and the sample loading seat 2 and the sample are water-cooled by an external water-cooling circulation device, so as to prevent the concentration of heat and ensure the normal progress of irradiation and subsequent steps.

[0018] Embodiment 2: The sample base 1 is also provided with a pair of sealing grooves 14 on the outside of the sample loading seat 2. Sealing rubber rings 15 are arranged in the sealing grooves 14. During the irradiation process of the sample, the edge of the irradiation cover is pressed against the upper end surface of the sample base 1 to achieve internal isolation and sealing.

[0019] In this embodiment, it is further disclosed that the sample base 1 has a sealing groove 14 and a sealing rubber ring 15 structure, so that during irradiation, the sealing rubber ring 15 can isolate the sample loading seat 2 and the sample from the external environment, thereby ensuring normal internal irradiation.

[0020] Embodiment three: A storage groove 16 is further provided on the side of the sample base 1 , and a storage box 17 is telescopically inserted into the storage groove 16 . A positioning groove 18 is provided in the storage box 17 , and the positioning groove 18 is used to accommodate idle modular frame strips 8 .

[0021] In this embodiment, a storage mechanism for idle modular frame bars 8 is further disclosed, and the required modular frame bars 8 are taken out by pulling out the storage box 17 and loaded onto the flip rack 7 .

[0022] Embodiment 4: A water cooling channel is provided in the flip frame 7, and the water cooling channel is connected to the water cooling liquid storage tank 11 through the hollow rotating shaft 6 connected thereto. When the external water cooling circulation device circulates and pumps the cooling medium, a flow path is formed in the flip frame 7. The flip frame 7 realizes heat exchange by contacting with the modular frame bars 8.

[0023] The hollow rotating shafts 6 on both sides of the turning frame 7 are sleeved in the connecting sleeves 19 . The connecting sleeves 19 are fixedly installed in the sample loading seat 2 and communicated with the water-cooled liquid storage tank 11 .

[0024] Magnetic sheets 20 are installed on the sides of the flip frame 7 and the modular frame strips 8, and the magnetic sheets 20 are used to realize a detachable connection between the flip frame 7 and the modular frame strips 8.

[0025] In this embodiment, a water cooling channel is further opened in the flip frame 7, and a flow path is formed in the flip frame 7 through an external water cooling circulation device, so that heat exchange is achieved through the contact between the flip frame 7 and the modular frame strips 8, and finally the heat on the modular frame strips 8 is transferred. The significance of this operation is that it can not only complete the cooling of the circular loading slots 4 and the rectangular loading slots 5, but also effectively cool the samples loaded on the flip frame 7, and the cooling medium enters the hollow rotating shaft 6 through the connecting sleeve 19, and finally enters the water cooling channel in the flip frame 7. The significance of this arrangement is that the hollow rotating shaft 6 not only serves as a fixed-axis rotating mechanism, but also serves as a transition channel for the cooling medium, and the detachable connection between the flip frame 7 and the modular frame strips 8 is achieved through the magnetic suction sheet 20.

[0026] Embodiment five: The number of the flipping mechanism is consistent with that of the flipping frame 7 and they correspond one to one. The flipping mechanism includes a pushing piston 21 and a flipping line groove wheel 22. The pushing piston 21 is arranged in a pumping tube 23 provided in the sample loading seat 2 for translational sliding. The pumping tube 23 is connected to an external pumping tube 24 through a channel provided in the sample loading seat 2 and the sample base 1. The external pumping tube 24 is connected to an external quantitative pump. The external quantitative pump is used to pump a quantitative fluid medium into or out of the pumping tube 23, thereby prompting the pushing piston 21 to move forward. The hollow shaft 6 is also provided with a torsion spring 25 which pushes the flip frame 7 to a horizontal initial state in the absence of external force. The flip line groove wheel 22 is coaxially fixedly connected to the hollow shaft 6. A traction rope 26 is wound around the flip line groove wheel 22. The traction rope 26 is fixedly connected to the pushing piston 21 at one end away from the flip line groove wheel 22. The pushing piston 21 pulls the traction rope 26 during the translational sliding process, thereby overcoming the elastic force of the torsion spring 25 and causing the flip frame 7 to undergo a fixed-axis flipping movement.

[0027] In this embodiment, the specific structure of the flipping mechanism is further disclosed. The flow medium is pumped through the external pumping tube 24 in a timed and quantitative manner by an external metering pump. The liquid enters the pumping tube 23 to push the piston 21 to perform telescopic movement. During the telescopic process, the piston 21 pulls the flipping line groove wheel 22 to rotate through the traction rope 26, thereby adjusting the adjustment angle of the flipping frame 7. Since the external metering pump can accurately pump the fluid medium, the flipping angle of the flipping frame 7 can be accurately controlled, so that the irradiation angle and the irradiation surface can be adjusted during the irradiation process.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
