Abstract

The Advanced Space-based Solar Observatory (ASO-S) was successfully sent to space from Jiuquan Launch center on Oct. 9, 2022. The ASO-S is dedicated to study solar flares, corneal mass eruptions and their connections with solar magnetic field and configured three instruments: a Full-disk solar vector MagnetoGraph (FMG), a Lyman-alpha Solar Telescope (LST), and a solar Hard X-ray Imager (HXI). Until Dec. 2023, the ASO-S has smoothly operated at 720 kilometers above Earth’s surface in a Sun-synchronous orbit for one more year. The HXI is one of the three key parts in this mission and adopts a spatial modulation technique to indirectly achieve image of solar hard X-rays. It is made up of a collimator, a spectrometer and an electrical control box. As the critical component, the collimator is responsible for incident X-ray modulation. This paper presents detailed design of HXI, especially the core part -- collimator. Secondly, ground tests, including characterization and spatial environmental tests of HXI collimator will be reported accounted for its indirect imaging principle. We will put forward some newly on-orbit results in the past one year. All design and test result as well as on orbit performance verifies that this equipment fully completed its expected goal and even presents a more wonderful status over expectations.
