Design of lunar-based extreme ultraviolet optical payload

In order to monitor and research 30.4 nm radiation chronically and omnibearingly generated by plasmasphere, a lunar-based extreme ultraviolet camera is developed. The optical-mechanical structure of the lunar-based extreme ultraviolet camera is designed based on the scientific target on a imaging of 30.4 nm radiation. A multilayer mirror optical system and a 30.4 nm photon counting detector are adopted as the design project, and two-dimensional tracing mechanism is used to trace the earth. The experimental result illustrates that the optical-mechanical structure of the extreme ultraviolet camera meets the need of imaging on 30.4 nm radiation generated by earth's plasmasphere, which verifies the feasibility of lunar-based extreme ultraviolet camera.
