Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of testing, and particularly relates to an automated device for testing the light output of a scintillator. Background Art
[0002] A scintillator is a special material that converts the kinetic energy of high-energy particles (such as X-rays) into light energy. When a high-energy particle hits a scintillator, the high-energy particle excites the atoms inside the crystal, causing electrons to jump from the valence band to the conduction band. When these electrons return to the ground state, the energy is released in the form of photons, producing a short light flash phenomenon.
[0003] Scintillators are increasingly widely used in many fields, such as nuclear medicine, high-energy physics, industrial flaw detection, etc. The light output performance of a scintillator is one of the key indicators for evaluating its quality and applicability. Existing testing devices often have relatively single functions and are difficult to comprehensively and accurately evaluate scintillators of different shapes and sizes, such as large flat scintillators, small-size, highly integrated scintillator arrays, resulting in limited versatility of the testing device and inability to meet diverse application requirements. At the same time, the comparability of test results is limited.
[0004] Therefore, the above problems need to be solved urgently. Summary of the Utility Model
[0005] Purpose of the utility model: To overcome the above deficiencies, the utility model provides an automated device for testing the light output of a scintillator, which can test scintillators of different shapes and sizes to meet the testing requirements of different application scenarios. Using the same testing device to test scintillators of different batches and specifications can ensure the consistency and reliability of product quality and promptly detect and correct deviations in the manufacturing process.
[0006] Technical solution: To achieve the above object, the present utility model provides an automated device for testing the light output of a scintillator, comprising: a shielding box body. The shielding box body is a hollow box body, with an exit port provided at the top of the shielding box body. An elevating frame is provided inside the shielding box body, and the elevating frame is arranged at the bottom of the shielding box body. A detector is provided on the upper side of the elevating frame, and the elevating frame drives the detector to move up and down. The scintillator to be tested is placed on the top surface of the detector. An energetic particle generator is provided on the upper side of the shielding box body, and the energetic particle generator emits energetic particles from the exit port towards the scintillator to be tested inside the shielding box body. During the test, the scintillator to be tested is placed on the top surface of the detector, the door of the shielding box body is closed, and the detector collects dark field picture data and transmits it to the test system. Then the energetic particle generator emits energetic particles, the energetic particles strike the scintillator to be tested, the scintillator scintillates, the detector captures the light emitted by the scintillator scintillation and converts it into an electrical signal, and the detector sends the electrical signal to the test system. The test system converts the received electrical signal into data and outputs and displays it on the display section. The above steps need to be repeated for multiple tests to ensure the test accuracy. And the entire test process is automated, greatly improving the test efficiency. The energetic particles propagate in a straight line after passing through the exit port, and the running route of the energetic particles forms a cone. That is to say, the larger the size of the scintillator that the energetic particles can cover as they are farther away from the exit port. The detector moves downward under the drive of the elevating frame, and the energetic particles entering from the exit port completely cover the scintillator to be tested. Therefore, the present utility model can adapt to evaluate scintillators of different shapes and sizes, improving the adaptability of the device and meeting diverse test requirements.
[0007] Further, in the above-mentioned automated device for testing the light output of a scintillator, the energetic particle generator is an X-ray machine. The X-ray machine can provide a stable and accurate radiation source, ensuring the repeatability and accuracy of the test results. The intensity and energy of the X-ray machine can be adjusted to simulate different application conditions and comprehensively evaluate the response of the scintillator under different radiation conditions.
[0008] Further, in the above-mentioned automated device for testing the light output of a scintillator, the shielding box body is a lead box. The lead box can effectively absorb and block radiation, thereby protecting the surrounding environment and personnel from radiation damage. During use, the integrity of the lead box should be regularly checked, and the corresponding safety operation procedures should be followed to ensure personnel safety.
[0009] Further, in the above-mentioned automated device for testing the light output of a scintillator, an energetic particle chopping device is provided inside the shielding box body. The energetic particle chopping device is arranged on the upper side of the detector, and the energetic particle chopping device slides horizontally left and right. The energetic particle chopping device chops the energetic particles entering from the exit port. The energetic particle chopping device can control the energy of the energetic particles to study the response characteristics of the scintillator, such as energy resolution, light output, etc.
[0010] Furthermore, in the above-mentioned automated device for testing the light output of a scintillator, the high-energy particle cutting device is a tungsten steel plate that moves horizontally left and right. The tungsten steel plate has excellent shielding performance and is more environmentally friendly, making it an ideal environmentally friendly radiation shielding material.
[0011] Furthermore, in the above-mentioned automated device for testing the light output of a scintillator, the exit port is a narrow slit or a small hole, and the high-energy particle cutting device can cut off high-energy particles in a shorter time.
[0012] Furthermore, in the above-mentioned automated device for testing the light output of a scintillator, the shielding box body is provided with double doors and a proximity switch. When starting the test, close the double doors. The double doors trigger the proximity switch, and the proximity switch emits a signal. The test system receives the signal and starts detection, and the detection process is automated. When the double doors are opened, the proximity switch disconnects, and the test system does not receive the proximity switch signal, and the device stops working to avoid high-energy particles from harming personnel.
[0013] Furthermore, in the above-mentioned automated device for testing the light output of a scintillator, the lifting frame is drivingly connected to a cylinder, and the cylinder drives the lifting frame to move up and down. When the cylinder drives the lifting frame to rise, the scintillator to be tested approaches the exit port, and the scintillator to be tested receives a higher impact of high-energy particles; when the cylinder drives the lifting frame to descend, the scintillator to be tested moves away from the exit port, and the scintillator to be tested receives a larger irradiation area of high-energy particles.
[0014] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects: The automated device of the present utility model for testing the light output of a scintillator is provided with a lifting frame to drive the scintillator to be tested to move up and down, which can adapt to evaluating scintillators of different shapes and sizes, improving the adaptability of the device and meeting diverse test requirements. The high-energy particle cutting device can control the energy of high-energy particles and study the response characteristics of the scintillator, such as energy resolution, light output, etc., improving the adaptability of the device.
