Space neutral atom imaging instrument calibration method and device

Abstract

The invention provides a space neutral atom imaging instrument calibration method. The method includes the following steps that: step 101, a particle transport calculation tool is adopted to calculate energy deposition values of different energy particles in a sensor, and corresponding relationships between particle energy and energy deposition are recorded; step 102, the corresponding relationships between the particle energy and the energy deposition are set according to the energy channel of an neutral atom imaging instrument, the energy deposition of the particles of neutral atoms of different energy in the sensor of the neutral atom imaging instrument is calculated, and the electron energy of the electrons of the neutral atoms is calculated according to the energy deposition which is obtained through calculation, and a plurality of energy-level energy points can be obtained; and step 103, an electronic detector and an instrument to be tested which are carried by a vacuum turntable in a vacuum tank measure electron beams sequentially, and therefore, comparison testing of various indicators of the instrument to be tested can be realized. With the space neutral atom imaging instrument calibration method and device provided by the invention adopted, calibration can be provided for instruments such as neutral atom detection instruments in energy, flux accuracy and resolution, and therefore, the quality of the research and development of the instruments can be ensured.

Description

technical field [0001] The invention relates to the technical field of space detection, in particular to a calibration test method and device for a space neutral atom imaging instrument. Background technique [0002] Advances in space environment science research indicate that space weather changes, especially magnetospheric substorms and magnetic storms, are characterized by global evolution. The plasma detection in the satellite local space only reflects the physical characteristics of the area the satellite passes through, and has both spatial and temporal variation factors. Spatial probing requirements for evolving physical signatures. For the particle response energy range and specific space regions, the development of particle imaging detection technology with telemetry function is an urgent requirement for space physics research and space weather environment monitoring. [0003] Neutral atom imaging is a high-tech application in space exploration in recent years, an...
