Plastic scintillator array detector front end electronics case of dark matter particle detection satellite

Abstract

The invention relates to the technical field of large detector front end electronics case structures on satellites, particularly to a plastic scintillator array detector front end electronics case of a dark matter particle detection satellite. The plastic scintillator array detector front end electronics case is characterized in that the case comprises a case body box, and the reverse side of the case body box is equipped with a high-voltage fan-out plate through a high-voltage fan-out plate strut and a fastener; one end of the case body box is equipped with a high-voltage joint panel and a wire binding frame by adoption of a fastener, and a high-voltage joint is mounted on the high-voltage joint panel; and the upper part of the case body box is equipped with a signal adapter plate through a signal adapter plate strut and a fastener. Matching of the plastic scintillator array detector front end electronics case with a detector structure is realized, performance of the detector front end electronics case is guaranteed to be stable, and requirements for capability of bearing complex space environment during in-orbit operation of an on-satellite product, high reliability of the product, compact structure and light weight are realized.

Description

technical field [0001] The invention relates to the technical field of the front-end electronics chassis structure of a large detector on a satellite, in particular to a front-end electronics chassis of a plastic scintillation array detector of a dark matter particle detection satellite.
