Abstract
The Advanced Space-based Solar Observatory (ASO-S) is the first Chinese solar mission and is scheduled to be launched in 2022. It is designed to study the solar magnetic field, coronal mass ejections, solar flares, and their relationships. The ASO-S includes three scientific payloads: the Full-disk vector MagnetoGraph, the Lyman-alpha Solar Telescope and the Hard X-ray Imager. As a key part onboard the ASO-S, the HXI will improve our understanding of solar flares during the 25th solar maximum. The HXI comprises three parts, namely a collimator (HXI-C), a spectrometer (HXI-S) and an electronics control box (HXI-E). Extensive environmental tests, such as mechanical and thermal tests are important for a space mission to ensure the design and performance are suitable for the severe challenges presented by the launch and on-orbit operations. This paper describes the procedures and results of environmental tests performed on the qualification model of the HXI-S. Functional tests of the spectrometer are reported as well. Test results show that the current qualification model fully satisfies mission requirements.
