Description

Technical Field

[0001] This specification relates to the field of radiation effect testing technology, and in particular to an irradiation experimental apparatus. Background Technology

[0002] Currently, during the operation of nuclear reactors, various devices and critical components within the reactor are exposed to strong radiation environments for extended periods. This leads to problems such as material degradation, electronic component failure, and mechanical structural damage due to prolonged exposure to nuclear radiation, including neutrons and gamma rays. Therefore, to ensure the safe and stable operation of nuclear reactors, every new piece of equipment or component used in a nuclear reactor must undergo rigorous radiation tolerance verification before being put into use. This involves exposing the test object to an irradiation field (such as neutron flux rate, gamma dose rate, etc.) that is the same as or similar to the actual working environment to accurately assess its reliability, functional stability, and lifetime characteristics under long-term irradiation.

[0003] When irradiating test objects such as capacitors, semiconductor devices, and integrated circuits, a bias voltage needs to be applied to ensure that the test object is irradiated under a non-zero applied voltage. This allows for the measurement of the test object's operating characteristics under the applied bias voltage and irradiation environment. However, due to the influence of the irradiation field generated by the irradiation experimental device, when an external circuit is connected to the irradiation experimental device to apply a bias voltage to the test object, problems such as arcing and short circuits may occur under the influence of the irradiation field.

[0010] Optionally, the heating tube 12 includes an electric heating element.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this specification clearer, the technical solutions of this specification will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of them. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

[0019] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0020] Currently, due to the influence of the irradiation field generated during the irradiation process, when an external circuit is connected to the irradiation experimental device to apply a bias voltage to the test object, the external circuit may experience problems such as arc discharge and short circuit under the influence of the irradiation field.

[0021] In addition, when it is necessary to adjust the bias voltage applied to the test object, it is also necessary to frequently open and close the door of the irradiation experimental device, which will affect the irradiation source and cause deviations in the irradiation experimental results.

[0022] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0023] This specification provides an irradiation experimental apparatus, which includes: a housing 1, an isolation tube 2, and connecting wires 3. The housing 1 can house a test stand 4 and an irradiation device 5. A power supply module 6 can be installed outside the housing 1. Figure 1 As shown.

[0024] Figure 1 This is a schematic diagram of an irradiation experimental apparatus provided in this specification.

[0025] Combination Figure 1 It can be seen that an isolation tube 2 can be provided in the above-mentioned irradiation experimental device. The isolation tube 2 can penetrate one side surface of the box 1, thereby forming a channel connecting the internal space and the external space of the box 1, so that the connecting wire 3 can pass through the channel inside the isolation tube 2, thereby enabling the power supply module 6 located outside the box 1 to apply a stable and controllable bias voltage to the test object on the test seat 4 located inside the box 1 through the connecting wire 3 protected by the isolation tube 2.

[0026] Specifically, the above-mentioned irradiation experimental device can also adopt an upper and lower structure design, with the upper part being the box 1 and the lower part being the base 7. In this case, the top of the base 7 is connected to the bottom of the box 1, and the power supply module 6 can be placed inside the base 7.

[0027] Based on this, the isolation tube 2 can penetrate one side of the housing 1 and one side of the base 7 at the same time, thereby forming a channel connecting the housing 1 and the base 7, so that the connecting wire 3 can pass through the channel inside the isolation tube 2.

[0028] In this specification, the two ends of the connecting wire 3 are respectively provided with connectors. Connector 31 at one end of the connecting wire 3 is connected to the power supply module 6, and connector 32 at the other end is connected to the interface 42 on the test socket 4.

[0029] As can be seen from the above, by placing the connecting wire 3 inside the cavity of the isolation tube 2, the connecting wire 3 can be protected by the isolation tube 2, thereby preventing the connecting wire 3 from being directly exposed to irradiation, and thus preventing problems such as arc discharge and short circuits from occurring under the action of the irradiation field.

[0030] In the above content, the material of the isolation tube 2 can be selected according to actual needs. However, if the isolation tube 2 is made of non-high-density material, although it can protect the wire to a certain extent, the protection effect of the isolation tube 2 on the connecting wire 3 is weak. Therefore, the isolation tube 2 can also be made of high-density material (such as lead, tungsten alloy, etc.) so that the irradiation shielding efficiency of the isolation tube 2 meets the preset irradiation shielding conditions.

[0031] It should be noted that the isolation tube 2 can be located in various positions within the irradiation experimental apparatus, such as... Figure 2 As shown.

[0032] Figure 2 This is a schematic diagram of the two isolation tubes provided in this instruction manual.

[0033] from Figure 2 As can be seen from a, the aforementioned isolation pipe 2 can vertically penetrate the bottom surface of the box 1 and the top surface of the base to form a channel connecting the box 1 and the base 7.

[0034] from Figure 2 As can be seen from b, the aforementioned isolation tube 2 can also horizontally penetrate the side of the box 1, and after extending vertically outside the box 1, penetrate the side of the base from the outside to the inside to form a channel connecting the box 1 and the base 7.

[0035] Furthermore, in the case where the aforementioned isolation tube 2 vertically penetrates the bottom surface of the housing 1 and the top surface of the base to form a channel connecting the housing 1 and the base 7, the shape of the aforementioned isolation tube 2 can be a straight tube.

[0036] When the isolation tube 2 is straight, if the horizontal distance between the bottom surface of one end of the isolation tube 2 and the test base 4 is greater than the length of the connector 32 itself, then when the connector 32 at one end of the connecting wire 3 is connected to the test base 4, part of the connecting wire, in addition to the connector 32, may be exposed to irradiation. This reduces the effectiveness of the isolation tube 2 in protecting the connecting wire 3, specifically as follows: Figure 3 As shown.

[0037] Figure 3 This is a schematic diagram showing the positional relationship between the connecting wires and the isolation tube provided in this instruction manual.

[0038] from Figure 3 As can be seen from point a, when the horizontal distance between the bottom surface of the isolation tube 2 inside the housing 1 and the test socket 4 is greater than the length of the connector 32 itself, a section of the connecting wire will inevitably be exposed outside the isolation tube if the connector 32 is to be connected to the test socket. Therefore, in order to improve the protection effect of the connecting wire through the isolation tube, the horizontal distance between the bottom surface of the isolation tube 2 inside the housing 1 and the test socket 4 can be no greater than the length of the connector 32, so that when the power supply module 6 is connected to the test socket 4 through the connecting wire 3, only the connector 32 is exposed to radiation. Figure 3 As shown in b.

[0039] It should be noted that the connectors 31 and 42 at both ends of the connecting cable 3 are not the same size. The connector 32, which is used to connect to the test socket 4, is larger than the connector 31, which is used to connect to the power supply module 6. Therefore, there are two methods to connect the connectors at both ends of the connecting cable to the test socket 4 and the power supply module 6, respectively. The first method is to first connect connector 31 to the power supply module 6, and then pass connector 32 through the channel formed by the cavity area inside the isolation tube 2 and connect it to the test socket 4.

[0040] At this time, since the volume of the connector 32 used to connect the test socket 4 is larger than that of the connector 31 used to connect the power supply module 6, the inner diameter of the isolation tube 2 needs to be larger than the maximum radial dimension of the connector 32 so that the connector 32 can pass through the above-mentioned channel. However, since the inner diameter of the isolation tube 2 needs to be larger than the maximum radial dimension of the connector 32, there is a large annular gap between the isolation tube 2 and the connecting line 3 (i.e., there is a large gap between the isolation tube 2 and the connecting line 3), which reduces the protective effect of the straight tube-shaped isolation tube 2 on the connecting line 3.

[0041] Therefore, the second method can be as follows: First, connect connector 32 to test socket 4, then pass connector 31 through the channel formed by the cavity area inside the isolation tube and connect it to power supply module 6. In this case, the inner diameter of the isolation tube 2 only needs to be greater than the maximum radial dimension of connector 31, while the maximum radial dimension of connector 31 is smaller than the maximum radial dimension of connector 32. This reduces the gap between the isolation tube 2 and the connecting wire 3, thereby improving the protection effect of the straight tube-shaped isolation tube 2 on the connecting wire 3.

[0042] In addition, to further enhance the protection effect of the connecting line 3 through the isolation tube 2, the isolation tube 2 can also be bent (such as L-shaped, U-shaped, or V-shaped). For ease of understanding, the following uses an L-shaped isolation tube 2 as an example to explain the bent isolation tube in detail. Figure 4 As shown.

[0043] Figure 4 This is a schematic diagram of the bent isolation tube provided in this instruction manual.

[0044] Combination Figure 4 As can be seen, the aforementioned isolation tube 2 can be configured as a bent L-shape. In this case, the isolation tube 2 can be divided into a vertical section 21 and a horizontal section 22. Based on this, the connector used to connect to the test socket 4 and at least part of the connecting wires can be protected through the horizontal section 22 of the isolation tube 2.

[0045] In the above-described irradiation experimental apparatus, the test stand 4 can be selected according to the analyte. Different analytes require different test stands 4. Here, the test stand 4 is as follows: Figure 5 As shown.

[0046] Figure 5 This is a schematic diagram of the test fixture provided in this manual.

[0047] Combination Figure 5 As can be seen, a groove 41 is provided on the top of the test socket 4, and an interface 42 can be provided on the side of the test socket 4. The groove 41 is used to fix the object under test. For example, if the object under test is a chip under test, the bottom of the groove 41 can be provided with an elastic probe array for connection with the chip under test, and the side wall of the groove 41 can be used to limit the horizontal displacement of the chip under test.

[0048] For example, if the object to be tested is an electrical component, the side wall of the groove 41 can be provided with a spring clamping structure, and the bottom of the groove 41 can be provided with a power supply circuit for supplying power to the electrical component to be tested.

[0049] In the above-mentioned irradiation experimental apparatus, the irradiation device 5 can be set on the top of the box 1. The irradiation device 5 is mainly composed of an irradiation source emitter, which is used to irradiate the test object on the test stand 4.

[0050] The aforementioned irradiation source emitter can be selected according to actual needs. For example, the aforementioned irradiation source emitter can be a Co-60 isotope source, which can irradiate the test object by emitting Co-60 particles through the radioactive source.

[0051] However, in practical applications, the required irradiance may vary in different regions of the test object. For example, when the test object is a photovoltaic cell, different irradiance rates are required for the edge region and the central PN junction region of the cell.

[0052] In order to meet the requirements of different irradiation rates for different irradiation areas, the irradiation device can also be equipped with an adjustable collimator. The slit width can be adjusted by the stepper motor of the adjustable collimator to control the irradiation rate of different irradiation areas.

[0053] In the above description, the power supply module is used to apply a bias voltage to the device under test in the test socket via a connecting wire.

[0054] As can be seen from the above, in the irradiation experimental device, the connection used to connect the power supply module and the test base can be protected by using an isolation tube made of high-density material. Thus, when conducting irradiation experiments through the irradiation experimental device, a controllable bias voltage can be applied to the test object through the power supply module and the connecting line. Furthermore, the isolation tube can prevent problems such as arc discharge and short circuit in the connecting line under the action of the irradiation field.

[0055] Meanwhile, since the power supply module is located in the base of the irradiation experimental device, the frequent opening and closing of the door of the enclosure 1 can be avoided when the bias voltage applied to the test object needs to be adjusted, so as to avoid affecting the irradiation source.

[0056] Based on this, since the test holder 4 is placed directly at the bottom of the chamber 1, there is a possibility that the test object may come into contact with the chamber 1, forming an unexpected conductive path and interfering with the application of the bias voltage. There is also a possibility that the chamber 1 may absorb or reflect some of the irradiation energy (such as X-rays or gamma rays), thus affecting the uniformity of the irradiation dose. Therefore, a stage 8 can also be provided at the bottom of the chamber 1, specifically as follows: Figure 6 As shown.

[0057] Figure 6 This is a schematic diagram of the stage provided in this specification.

[0058] Combination Figure 6It can be seen that the test stand 4 can be placed on the stage 8, and the test stand 4 can be separated from the bottom of the box 1 through the stage 8 to isolate interference.

[0059] The platform 8 is also equipped with baffles 81 and 82 on both sides.

[0060] In addition, during the irradiation experiment on some test objects, in addition to controlling the bias voltage applied to the test object, it is also necessary to control the ambient temperature of the test object.

[0061] Therefore, the above-mentioned irradiation experimental apparatus may further include a heating device 10, wherein the heating device 10 is used to provide different ambient temperatures to the test object during the irradiation experiment. Specifically, as follows... Figure 7 As shown.

[0062] Figure 7 This is a schematic diagram of the heating device provided in this specification.

[0063] Combination Figure 7 As can be seen, the heating device 10 mentioned above may include: a water cavity 11, which may be located inside the housing 1. The water cavity 11 is also provided with a heating pipe 12. The water cavity 11 may be placed directly below the platform 8. The heating pipe 12 may be used to heat the water in the water cavity 11.

[0064] As can be seen from the above, a water chamber 11 can be set below the stage 8, and the water in the water chamber 11 can be heated by the heating pipe 12 in the water chamber 11, so as to control the ambient temperature of the test environment where the test object is located.

[0065] The heating tube 12 described above can use a resistance wire as an electric heating element (i.e., a heating source). However, when the resistance wire is energized and heated, it will generate broadband electromagnetic noise (especially the power frequency 50 / 60Hz and its harmonics), which may cause coupling interference with the bias voltage applied to the test object, thereby reducing the accuracy of the experimental results of the irradiation experiment on the test object under the specified bias voltage.

[0066] Therefore, the heating element provided in the heating tube 12 can be a positive temperature coefficient heating tube (PTC) heating tube. At this time, when the temperature of the heating element is in the first temperature range, the resistance value of the heating element is constant, and when the temperature of the heating element is in the second temperature range, the resistance value of the heating element increases in a stepwise manner.

[0067] The maximum value in the first temperature range is less than the minimum value in the second temperature range.

[0068] Different PTC heating elements have different first and second temperature ranges, and the heating elements installed in the water cavity can be selected according to actual needs.

[0069] It should be noted that, since the resistance of the aforementioned heating element increases dramatically when the temperature of the heating element is in the second temperature range, the resistance of the heating element will rise sharply (up to a thousand times the original resistance) when the ambient temperature inside chamber 1 reaches the specified temperature (e.g., 70 degrees Celsius). The sharp increase in the resistance of the heating element can reduce the current and the heat generation, thereby improving the safety of the irradiation experiment.

[0070] Based on this, in order to further improve the accuracy of temperature control during the irradiation experiment and to improve the uniformity of the ambient temperature, the heating device 10 mentioned above can also be a water circulation heating device, including: an inlet pipe 13, an outlet pipe 14, a water reservoir 15, and a water pump 16, specifically as follows: Figure 8 As shown.

[0071] Figure 8 This is a schematic diagram of the water circulation heating device provided in this manual.

[0072] Combination Figure 8 As can be seen, in the heating device 10 described above, the water cavity 11 can be provided with an inlet and an outlet on both sides respectively. One end of the inlet pipe 13 can be connected to the inlet of the water cavity 11, and the other end can pass through the surface of one side of the housing 1 and connect to the water storage tank 15, thereby forming an inlet channel. One end of the outlet pipe 14 is connected to the outlet of the water cavity 11, and the other end of the inlet pipe 13 passes through the surface of one side of the housing 1 and connects to the water storage tank 15, thereby forming an outlet channel. The water pump 16 described above is used to pump water from the water storage tank 15 into the water cavity 11 through the inlet channel after the water in the water cavity 11 reaches the specified temperature, so that water circulation occurs between the water cavity 11 and the water storage tank 15.

[0073] In practical applications, to efficiently heat the water in the water chamber to a specified temperature, valves can be installed in both the inlet pipe 13 and the outlet pipe 14. Before the heating element 12 starts heating, the valve in the inlet pipe 13 can be opened, and water from the water storage tank 15 can be pumped into the water chamber 11 through the inlet channel by the water pump 16. When the heating element 12 starts heating, the valve in the inlet pipe 13 can be closed. After the water in the water chamber 11 reaches the specified temperature, both the valves in the inlet pipe 13 and the outlet pipe 14 are opened, and water from the water storage tank 15 is pumped into the water chamber 11 through the inlet channel by the water pump 16, so that a slow water circulation occurs between the water chamber 11 and the water storage tank 15. The PTC heating element continues to heat the water to maintain a constant water temperature in the water chamber 11, thereby simulating a constant ambient temperature.

[0074] In addition, in order to improve the efficiency of water circulation between the water chamber 11 and the water reservoir 15, the above-mentioned inlet pipe and outlet pipe can be set in multiple ways according to actual needs. For example, two inlets and two outlets can be set in the water chamber 11, so that two channels for water inlet and two channels for water outlet can be formed between the water chamber 11 and the water reservoir 15 through the two inlet pipes and the two outlet pipes respectively.

[0075] As can be seen from the above, the heating device 10 based on water circulation and PTC heating tube can provide a controllable bias voltage and a controllable ambient temperature to the test object during the irradiation experiment, thereby improving the accuracy of the irradiation experiment.

[0076] Furthermore, in order to accurately reflect the temperature of the stage and the radiation dose received by the object under test, a temperature detector and / or a semiconductor detector can be installed inside the housing 1. To improve the accuracy of the measurement data, the temperature detector and / or semiconductor detector can be located in the controller layer 17 between the water chamber 11 and the stage 8. Specifically, as follows... Figure 9 As shown.

[0077] Figure 9 This is a schematic diagram of the controller layer provided in this specification.

[0078] Combination Figure 9 It can be seen that by setting a detector layer 17 between the water cavity 11 and the stage 8, and by placing at least one detector, such as a temperature detector or a semiconductor detector, in the detector layer 17, the temperature of the stage and the dose of radiation received by the test object can be accurately measured, and the measured temperature of the stage and the dose of radiation received by the test object can be fed back to the control console 18.

[0079] In this specification, the above-mentioned irradiation experimental apparatus may further include: a control console 18, which is physically or signal-connected to the power supply module 6. The control console 18 is used to set the voltage for the power supply module 6 so that the power supply module 6 applies a bias voltage to the test object according to the set voltage.

[0080] The location of the aforementioned control console can be set according to actual needs. In practical application scenarios, the control console can be located between housing 1 and base 7, as shown below. Figure 10 As shown.

[0081] Figure 10 This is a schematic diagram of an irradiation experimental apparatus with a control console provided in this specification.

[0082] Combination Figure 10As can be seen, when the aforementioned control console 18 is located between the housing 1 and the base 7, the interior of the aforementioned control console 18 can be a hollow structure, so that the aforementioned isolation pipe 2 and water pipe, after passing through the bottom surface of the housing 1, can pass through the hollow area located in the middle of the control console 18, and then can be connected to the power supply module 6 and the water storage device 15 respectively after passing through the top of the base.

[0083] In practical applications, the heating element 12 also needs to be connected to the power supply module 6 via a connecting wire. Furthermore, a constant voltage is required when heating with the heating element 12, while a transformer is needed when applying a bias voltage to the test object on the test socket. Therefore, the power supply module 6 can include a constant voltage source 61 and a transformer voltage source 62. Two connecting wires can be connected from the power supply module 6. The connectors at both ends of one connecting wire are used to connect to the transformer voltage source 62 and the test socket 4, respectively, while the connectors at both ends of the other connecting wire are used to connect to the constant voltage source 61 and the heating element 12, respectively.

[0084] At this time, the isolation tube mentioned above may include two outlets, namely, a first outlet and a second outlet. The second outlet may be located below the first outlet, at the same height as the heating device. The connector for connecting the transformer voltage source 62 and the test socket 4 may be connected to the test socket via the first outlet, and the connector for connecting the constant voltage source 61 and the heating tube 12 may be connected to the heating tube 12 via the second outlet.

[0085] It should be noted that the aforementioned control console 18 may be equipped with control buttons for controlling the bias voltage and temperature. In this case, the control console 18 can control the power supply module 6 based on the control operation performed by the tester using the control button for controlling the bias voltage, thereby controlling the bias voltage applied to the test object by the test socket 4; or, based on the control operation performed by the tester using the control button for controlling the temperature, it can control the power supply module 6, thereby controlling the voltage supplied to the heating device 10 to control the ambient temperature of the test object.

[0086] As can be seen from the above, by placing the power supply module 6 in the base 7 of the irradiation experimental device and connecting it to the isolation tube 2, under the protection of the isolation tube, the bias voltage applied to the test object can be dynamically adjusted according to actual needs in the irradiation environment. Furthermore, by connecting it to the heating device 10 under the protection of the isolation tube 2, the ambient temperature of the test object can be dynamically adjusted according to actual needs in the irradiation environment. This allows for accurate simulation of the actual working environment of the test object, thereby improving experimental efficiency and the accuracy of experimental results.

[0087] The above description is merely an embodiment of this specification and is not intended to limit this specification. Various modifications and variations can be made to this specification by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this specification should be included within the scope of the claims of this specification.
