A power supply circuit on the second amplifier board (5) is connected to the first amplifier board (4) through a wire, and supplies power to the integrated preamplifier ASIC chip. The second detection unit bracket (3) and the first detection unit bracket (2) are fixed integrally.

Description

technical field [0001] The invention relates to the technical field of space particle radiation detection load, in particular to a detection probe with an integrated design of a medium-energy electronic detector. Background technique [0002] Since the discovery of the Earth's radiation belts by American scientist James Van Allen in 1958, intermediate-energy particles (including electrons, protons and other ions) with energies ranging from 1 keV to several MeV have attracted widespread interest. Medium-energy particles exist in various regions of the magnetosphere and their boundary layers. They are important causes of many space physical phenomena such as auroras, magnetic storms, and high-energy electron storms in the earth's magnetosphere. important factor in. The acceleration mechanism of intermediate energy particles in the magnetosphere and its origin are the two most basic problems to be solved in the current study of intermediate energy particles. In addition, inte...

AI Technical Summary

Problems solved by technology

This design will increase the electronic noise of the whole system and is susceptible to external interference

Therefore, the system noise of traditional binary or multi-element semiconductor detector telescope particle radiation detectors is usually greater than 10keV, so it cannot meet the needs of medium-energy electron detectors for accurate measurement of the 50-600keV medium-energy electron spectrum
