Composite energy particle detector for deep space exploration and design method thereof

Abstract

The invention relates to a composite energy particle detector for deep space exploration and a design method thereof, and belongs to the technical field of space particle detection. The method comprises the following steps of firstly, determining a field angle of the detector; determining the components required by the detector; arranging a light barrier on the lower bottom surface of a collimator; arranging a silicon detector I, a silicon detector II and a CsI (T1) detector sequentially and coaxially below the light barrier from top to bottom; determining the sizes of the three sub-detectorsaccording to the energy deposition of different particles on different detectors and the types and energy sizes of the energy particles to be detected, and enabling the edge points of the detectors tobe located in a reverse extension line of a bus of an inverted circular truncated cone; and arranging the anticoincidence detector in an area outside the three sub-detectors. The method is suitable for a multi-particle composite detection system for deep space radiation environment detection, and is used for the integrated detection of charged particles with multiple energy sections, multiple particle types and a wide energy spectrum.

Description

technical field [0001] The invention relates to a composite energy particle detector for deep space exploration and a design method thereof, belonging to the technical field of space particle detection. Background technique [0002] In recent years, with the gradual development of the aerospace industry, my country's space activities have gradually shifted from earth orbit exploration to deep space exploration. The space charged particle radiation environment is one of the most notable characteristics of the space environment, and it is the main research object of the space environment. Solar energy particles and galactic cosmic rays are the main sources of space particle radiation. Therefore, the research on the energy spectrum of different kinds of charged particles from the deep space environment will help humans to further understand the deep space radiation environment, which will provide radiation safety for humans to improve the design of spacecraft and ensure astron...

AI Technical Summary

Problems solved by technology

[0005] Space radiation environmental particle detectors are widely used in orbit, but the existing experimental devices for the detection of space radiation charged particles mainly have the following problems: (1) The measurement target is single

For example, a single instrument can only realize the measurement of a single type of electron or proton, or can only realize the simultaneous measurement of light nuclei such as electrons and protons, but cannot achieve the integrated measurement of electrons, protons and heavy ions

(2) It is impossible to realize the identification of multiple types of charged particles and the composite detection of wide energy ranges

For example, a single instrument of the existing space radiation particle detector can only detect the energy of a single charged particle in the low-energy, medium-energy, and high-energy ranges, and cannot meet the design requirements of multiple particles and wide-energy ranges.

(3) It cannot meet the functions of multi-type particle energy detection and type identification and the requirements of low power consumption, light weight and low development cost of deep space detection instruments

The existing space radiation particle detectors cannot meet the above detection characteristics at the same time, so it is necessary to design a composite deep space radiation particle detector with low power consumption, miniaturization and multi-particle detection function, so as to accurately and effectively detect deep space radiation particles environment, providing scientifically valid data for future deep space weather exploration
