Description

technical field [0001] The invention generally relates to the field of aerospace technology, in particular to a micro-charged particle accelerator for in-situ detection of loads in the middle and upper atmospheres. Background technique [0002] The space environment detection load refers to the load product used to detect the space environment parameters, and it needs to ionize, accelerate and collect the particles during the detection process. The design of the traditional ion optical system based on beam transmission theory is complicated. Specifically, multiple sets of lens electrodes are used to finely design the electric field distribution, so as to construct an ion optical system with a high pass rate. [0003] Since the ion optical system has different focal positions during beam transmission for different particle components (different mass numbers), the transmittance of different particles in the ion optical system is also different. This is unacceptable for applic...

Problems solved by technology

However, if the ground calibration test is used, the actual vacuum environment in space cannot be completely simulated, and the calibration results have large errors; and if the on-orbit calibration method is used, it is very difficult to implement, the cost is high, and it is often impossible to achieve

At the same time, the ion optical system needs to arrange metals of different shapes and sizes, which will result in a large volume and weight, and is not suitable for application scenarios of miniaturized detection loads
