Analysis of core technical requirements

Detector composition

The standard stipulates that space high-energy electron detectors must include:

≥3 semiconductor sensor arrays
Electronic circuit processing system (including pre/main amplifier, high-voltage circuit, etc.)
Space-grade structural parts

Typical application: A satellite project uses a silicon PIN sensor array to achieve 200KeV-10MeV electron energy spectrum measurement with an energy channel resolution of 8 channels.

Environmental adaptability verification system

Test items	Identification level conditions	Acceptance level conditions
Thermal vacuum test	-20℃~55℃/3 cycles	-15℃~50℃/1 cycle
Random vibration	10.0g(25-100Hz)	6.0g(25-100Hz)
Electrostatic discharge	10kV arc discharge

Implementation Suggestions

Component Selection: Give priority to radiation-resistant devices in the aerospace model catalog, with a single-particle upset threshold ≥50MeV·cm²/mg
Process Control: Strictly implement the key process control requirements of QJ2664, and pay special attention to the airtightness of sensor packaging
Test Verification: It is recommended to increase the on-orbit data comparison link and verify the calibration results through actual space environment data
