我们已制作了一种非离子化能量损耗(NIEL)光谱仪实验架,本来打算在MIR宇宙空间站进行飞行试验,由于后来取消了飞行,就在加拿大蒙特利尔大学的实验室中试验了该光谱仪实验架。在采用常规TLD测量离子剂量的同时,也采用GaAs和SiC LED测量了NIEL,即非离子化元器件的能量损耗。本文叙述了用作NIEL监测器的CaAs LED的设计准则及其测试。 We have produced a non-ionized NIEL spectrometer experiment rack originally intended for flight tests at the MIR Space Station, which was tested in a laboratory at the University of Montreal in Canada after the flight was canceled. While using a conventional TLD to measure ion doses, NIEL was also measured using GaAs and SiC LEDs, ie, the energy loss of non-ionized components. This article describes the design guidelines and tests for CaAs LEDs used as NIEL monitors.
