Abstract
Ground-based calibration of the X-ray Mirror Assemblies (XMAs) of the XRISM satellite was performed at the X-ray beamline at NASA’s Goddard Space Flight Center. A raytracing simulator has been developed by the HITOMI and XRISM teams and tuned to reproduce the calibration data. In this paper, we first give an overview of the ground calibration results obtained from raster scans and local spot scans. We then present the process used to tune the simulator parameters in order to match the calibration measurements. Finally, we show a comparison of the simulated results with the measured effective areas, vignetting curves, and point spread functions.

Dr. Rozenn Boissay-Malaquin is an Assistant Research Scientist at the NASA Goddard Space Flight Center. After obtaining her master's degree in Strasbourg (France) and her Ph.D. in Geneva (Switzerland), she was hired as a postdoc at MIT. She then joined NASA Goddard in October 2019, to work on the calibration of the mirrors for the XRISM mission. Her research interests focus on Active Galactic Nuclei, and she is working on several scientific research projects based on X-ray observations from various observatories.
