空间中能电子多次散射对探测结果的影响

The Impact of Multiple Scattering on Space Medium-energy Electron Detection

使用MC法模拟了中能电子的多次散射过程,对不同能量中能电子在多次散射条件下的探测结果进行了比较。使用电子加速器对研制的中能电子探测器进行了测试,验证了该物理过程对探测结果的影响。分析了加速器测试和仿真结果的异同,提出了针对多次散射过程的传感器优化设计方法。

In this work, the transport process of medium-energy electron in silicon detector was simulated using Geant4, and the impact of multiple scattering on detection results under different conditions was analyzed. Accelerator test results of a medium-energy electron detector （MEED） were consistent with the simulation results. Based on both test and simulation results, some optimization methods of detector design are proposed to reduce the impact of multiple scattering.
