specific Embodiment approach 1

[0017] Embodiment 1: A method for detecting the fluence of a proton / electron integrated radiation beam in this embodiment is carried out according to the following steps:

[0018] 1. Determine the energy of proton irradiation source and electron irradiation source;

[0019] 2. Determine the detection material according to the energy of the proton radiation source and the electron radiation source in step 1. The determination principle is that the thickness of the detection material for which the proton radiation source is completely lost is not less than 3 μm;

Abstract

The invention relates to a test method of proton / electronic synthetical irradiation beam fluence and aims to solve the technical problems that only radiation flux of one kind of incident particle beam current can be tested, and when proton / electronic is synthetically irradiated, a beam-current integrator can not display corresponding radiation flux in the prior art. A synthesis method comprises the following steps: a, confirming comprehensive irradiation source energy, b, confirming test materials, c, calculating radiation distance of a comprehensive irradiation source in the test materials, d, confirming the thickness of the test materials according to the radiation distance, and e, obtaining proton / electronic synthetical irradiation beam fluence according to test of a beam-current integrator. The problem that when two incident particles which have approximate flux radiate at the same time, the beam-current integrator can not display in the prior art is solved. The test method of the proton / electronic synthetical irradiation beam fluence can test the fluence of different radiation particle beam currents, is convenient to operate, is high in accuracy, and can be used in ground synthetical irradiation experiment.

Description

technical field [0001] The invention relates to a method for detecting the fluence of a proton / electron comprehensive irradiation beam. Background technique [0002] At present, when conducting ground irradiation tests at home and abroad, the beams of incident particles (protons, electrons, heavy ions, etc.) are mainly detected in situ by beam integrators, but these irradiation tests are mainly for a specific energy Incident particles are detected, for example, 10MeV protons, 1MeV electrons, 170keV protons, 100keV electrons, 50MeV Br ions, etc. The in-situ detection of incident particles with a specific energy is relatively simple, that is, selecting a suitable detection material (such as Al material) and adding a beam integrator can complete the above work. [0003] When two kinds of incident particles are irradiated at the same time, especially the fluxes of the incident particles are similar, the above simple detection method cannot detect the irradiation fluence of the ...
