Abstract

The invention discloses a space high-energy electron detector. By means of the space high-energy electron detector, space 3.0-30.0 MeV high-energy electrons can be detected. The space high-energy electron detector comprises a probe shell, a light blocking piece, a semiconductor detector body I, a semiconductor detector body II, a semiconductor detector body III, a CsI(T1) scintillator and two photodiodes. The Au-Si surface barrier detectors and a CsI(T1) detector are combined, and the photodiodes are used for coupling the CsI(T1) detector. On one hand, due to the fact that the CsI(T1) detector is easy to machine, very thick sensors can be manufactured, and the detecting requirements for high-energy electrons can be met; on the other hand, the photodiodes, instead of photomultipliers, are adopted for coupling the CsI(T1) detector, therefore, the size and the weight of the space high-energy electron detector can be greatly reduced, and important engineering significance is achieved for satellite loads.

Description

technical field [0001] The invention relates to the technical field of space charged particle detection, in particular to a space high-energy electron detector, which can detect the flux of 3.0-30 MeV electrons in space. Background technique [0002] High-energy electrons are one of the important components of the space radiation environment, and they are one of the important factors that cause radiation damage to spacecraft electronic systems and electronic components. Since the beginning of space exploration activities, space high-energy electrons have become one of the important objects of space exploration. Over the past 50 years, many charged particle detectors have been launched to detect and study high-energy electrons in space, and some data about high-energy electrons in space have been obtained. [0003] However, due to the variability of the space environment, people's understanding of space high-energy electrons is still relatively limited, and it is necessary t...
