[0002] Using two or more different detectors to record two or more simultaneous and interrelated nuclear events is called coincidence measurement. Coincidence measurement is a commonly used measurement technique in nuclear physics experiments. It can be used to measure the energy and angular distribution of particles released in reactions. Radioactivity refers to the number of atoms of a radioactive element or isotope that decays per second. It is an important radiation quantity used to describe the characteristics of radioactive nuclides. It reflects the nuclear decay rate of radioactive nuclides.

[0003] During the experiment, the distance between the two detectors will affect the measurement results of the detector efficiency, and the experiment is generally carried out multiple times, and the average result is finally taken. The current way to measure the distance between the two detectors is for the experimenter to hold a ruler and measure the distance between the two detectors. This measurement method is prone to errors and has poor experimental repeatability. Utility Model Content

[0025] Among them, the support member 200 supports the detector in English, and the measuring group 300 is used to measure the distance between the two detectors; the support member 200 is arranged on the top of the slide rail 100, and the support member 200 and the slide rail 100 are slidably connected, and such an arrangement enables the support member 200 to slide back and forth on the slide rail 100; the number of the support members 200 is two, and the support member 200 is suitable for fixing the detector, and the detector is arranged along the length direction of the slide 100. Because two detectors are needed in the experiment, two supports are also needed, and the two detectors need to be arranged along the length direction of the slide rail for easy measurement; the measuring group 300 includes a scale 310 and a movable part 320, and the scale 310 is arranged along the length of the slide rail 100 Direction setting; the number of movable parts 320 is two, one end of the movable part 320 is connected to the support part 200, the measuring end of the movable part 320 extends forward to the top of the scale 310, and the movable part 320 is connected to the support part 200. This setting is to enable the support part 200 to drive the movable part 320 to move during the movement to measure the distance between the two detectors. Because the movable part 320 measures the distance between the two detectors, the number of movable parts 320 is also two, and because the front and rear sides of other components arranged on the slide rail 100 are outside the front and rear sides of the slide rail, the movable part 320 is required to extend forward to avoid friction or collision during the measurement process.

[0026] The length direction described in this article is specifically Figure 1 From left to right, the length of the rail is Figure 1 The left side Figure 1 direction to the right.

[0027] In a possible implementation, the projection of the movable member 320 in the length direction is an “L”-shaped structure, and the movable member 320 includes a connecting plate 321 and a measuring plate 322 , and the connecting plate 321 and the measuring plate 322 are fixedly connected.

[0028] Specifically, Figure 1 As shown, because the movable part 320 extends forward, the projection of the movable part 320 in the length direction is an "L"-shaped structure. The movable part 320 includes a connecting plate 321 and a measuring plate 322. The connecting plate 321 is used to connect the support part 200. The connecting plate 321 and the measuring plate 322 are fixedly connected. The measuring plate 322 is connected to the support part 200 through the connecting plate 321.

[0029] In a possible implementation, the connecting plate 321 is attached to the front side of the support member 200, and the connecting plate 321 and the support member 200 are bolted together; the measuring plate 322 is arranged on the front side of the connecting plate 200, the measuring plate 322 is an "L"-shaped structure, and the measuring plate 322 is arranged on the top of the scale 310; both measuring plates are extended toward the center position in the length direction of the slide rail; the extension direction of the measuring plate is inclined relative to the horizontal plane, and there is a preset angle α between the measuring plate and the horizontal plane, and the value range of the preset angle α is: 10°≤α≤15°.

Because there are two measuring devices, there are also two measuring plates 322. In order to make it easier for experimenters to see the degree, a preset angle α is provided between the measuring plate 322 and the horizontal plane, and the value range of the preset angle α is: 10°≤α≤15°, and such a setting avoids the measuring plate 322 rubbing back and forth on the scale, resulting in unclear scale numbers on the scale.

[0031] In a possible implementation, the middle position of the scale 310 in the length direction is the “0” scale, and the “0” scale corresponds to the middle position of the slide rail 100 in the length direction.

[0032] Specifically, Figure 1 As shown, in order to make it easier for the experimenter to see the distance between the two detectors, the middle position of the scale 310 in the length direction is the "0" scale, and the "0" scale corresponds to the middle position in the length direction of the slide rail 100. This setting enables the experimenter to quickly see the distance between the two detectors.

[0033] In a possible implementation, the two support members 200 are symmetrically arranged at the middle position along the length direction of the slide rail 100; when the intersection of the two detectors is located at the top of the middle position of the slide rail in the 100 degree length direction, the extended ends of the two measuring plates 322 are located at the "0" scale position.

[0034] Specifically, Figure 1 As shown, in order to make the measurement results more accurate, the two support members 200 are symmetrically arranged at the middle position along the length direction of the slide rail 100; when the intersection of the two detectors is at the middle position of the 100 degree length of the slide rail, the extended ends of the two measuring plates 322 are located at the "0" scale position.

[0035] In a possible implementation, a base 400 is further included. The base 400 is a rectangular plate-shaped structure, and the slide rail 100 and the measurement group 300 are both disposed on the base 400 .

[0036] Specifically, Figure 1 As shown, a base 400 is also included. Since the slide rail 100 is rectangular, the base 400 is a rectangular plate-shaped structure. The slide rail 100 and the measuring group 300 are both arranged on the base 400, and the base 400 plays an overall supporting role.

[0037] In a possible implementation, the slide rail 100 and the scale 310 are both arranged along the length direction of the base 100; a groove is opened on the base 400, the groove is arranged along the length direction of the base, and the scale 310 is placed in the groove.

[0038] Specifically, Figure 1 As shown, in order to fix the scale 310, a groove is provided on the base 400. The scale 310 is arranged in the groove, so that the scale 310 is fixed.

[0039] In a possible implementation, blocks are provided at both ends of the slide rail 100 , and the top height of the blocks is higher than the top height of the slide rail 100 , and the distance between the front and rear sides of the blocks is greater than the distance between the front and rear sides of the slide rail 100 .

[0040] Specifically, Figure 1 As shown, in order to prevent the measuring group 300 and the support member 200 from sliding out of the slide rail 100 during the measurement process, blocks are provided at both ends of the slide rail 100, and the top height of the block is higher than the top height of the slide rail 100, and the distance between the front and rear sides of the block is greater than the distance between the front and rear sides of the slide rail 100.

[0041] When the present application is used, the detector is installed on the support 200, and the distance between the two detectors is adjusted according to the experimental requirements. The support 200 moves on the slide rail 100. When the distance between the extended ends of the two measuring plates 322 is the required distance, the movement of the detector is stopped, and the experiment can be started at this time.

[0042] The present application is provided with a slide rail 100, a support member 200 and a measuring group 300. The support member 200 is provided at the top of the slide rail 100, and the support member 200 and the slide rail 100 are slidably connected. Such a setting enables the support member 200 to slide back and forth on the slide rail 100. There are two support members 200, and the support member 200 is suitable for fixing the detector. The detector is arranged along the length direction of the slide rail 100. Because two detectors are needed in the experiment, two support members are also needed. The two detectors need to be arranged along the length direction of the slide rail for convenient measurement. The measuring group 300 includes a scale 310 and a movable member 320. The scale 310 is arranged along the length direction of the slide rail 100. There are two movable members 320, and one end of the movable member 320 is connected to On the support member 200, the measuring end of the movable member 320 extends forward to the top of the scale 310, and the movable member 320 is connected to the support member 200. This arrangement is to enable the support member 200 to drive the movable member 320 to move during the movement to measure the distance between the two detectors. Because the movable member 320 measures the distance between the two detectors, the number of the movable members 320 is also two, and because the front and rear sides of other components arranged on the slide rail 100 are outside the front and rear sides of the slide rail, the movable member 320 needs to extend forward to avoid friction or collision during the measurement process. Through the above arrangement, the present application can accurately measure the distance between the two detectors to avoid measurement errors and cause deviations in the final results.
