Query: Design and verification of the HXI collimator onboard the ASO-S mission   A space-borne hard X-ray collimator, comprising 91 pairs of grids, has been
developed for the Hard X-ray Imager (HXI). The HXI is one of the three
scientific instruments onboard the first Chinese solar mission: the Advanced
Space-based Solar Observatory (ASO-S). The HXI collimator (HXI-C) is a spatial
modulation X-ray telescope designed to observe hard X-rays emitted by energetic
electrons in solar flares. This paper presents the detailed design of the HXI-C
for the qualification model that will be inherited by the flight model. Series
tests on the HXI-C qualification model are reported to verify the ability of
the HXI-C to survive the launch and to operate normally in on-orbit
environments. Furthermore, results of the X-ray beam test for the HXI-C are
presented to indirectly identify the working performance of the HXI-C.
