Embodiment Construction

[0026] The structural composition of the device for measuring the fluence rate and uniformity of the low-energy ion beam of the exemplary invention is as follows Figure 1-4 As shown, it includes a high-voltage power supply 4, an electronic plug-in 6 (specifically a scaler), a computer 7, a detector assembly 21, a positioning shaft 22, a fixing plate 23 (made of transparent acrylic material), a locking ring 25, and a locking ring. Nail 26, clamping frame 30. Among the above components, except that the electronics plug-in 6 and the computer 7 are located in the measurement hall, the rest of the components are located in the experiment hall.

[0027] Five sets of cylindrical detector assemblies 21 used to generate, amplify and transmit sample fluence rate and uniformity measurement signals can be fixed on the fixed plate 23 within the range of 5cm×5cm, and the diameter of each detector assembly 21 is less than 12mm.

[0028] The surface of the holder 30 is divided into a detec...

Abstract

The invention belongs to the technical field of nuclear radiation detection, and relates to a device for measuring the fluence rate and uniformity of a low-energy ion beam flow. The device comprises aclamping frame, positioning shafts, a fixed plate and detector assemblies, wherein samples are placed in partitioned regions of the surface of the clamping frame, and the fixed plate is fixed throughthe positioning shafts. The fixed plate can make axial motion along the positioning shafts. The detector assemblies which are used for generating, amplifying and transmitting the sample fluence rateand uniformity measurement signals can be fixed on the fixed plate. The device provided by the invention can quickly and accurately measure the fluence rate and uniformity of the low-energy ion beam flow.

Description

technical field [0001] The invention belongs to the technical field of nuclear radiation detection, and relates to a device for measuring the fluence rate and uniformity of low-energy ion beams. Background technique [0002] In recent years, the research on biological damage caused by proton and heavy ion radiation and radiation breeding has attracted more and more attention. The special pipeline device for radiation biology established on the R20 branch pipeline of the HI-13 tandem accelerator of China Institute of Atomic Energy Related work has been carried out in radiation biological breeding. [0003] However, the current beam diagnosis method used by this device is a method of multi-point scanning of a single detector. This method is time-consuming and cannot quickly diagnose the uniformity and fluence rate of the beam, thus wasting precious beam stream time. In order to meet the needs of rapid measurement of beam fluence rate and uniformity during the experiment, it ...
