In-orbit performance of the Xtend-XMA onboard XRISM

Abstract
Two complementary X-ray telescopes, Resolve and Xtend are on-boarded on the X-ray astronomy satellite XRISM (X-Ray Imaging and Spectroscopy Mission). In this presentation, in-orbit performance of the Xtend-XMA will be reported. Xtend uses an X-ray CCD camera as its focal plane detector, which has high spatial resolution and a wide field of view. This makes it possible to obtain detailed PSF of the Xtend-XMA. And also the energy resolution of the X-ray CCD camera makes it possible to determine the energy-dependent effective area of the Xtend-XMA. We can verify that these performances are sufficient to meet the mission requirements and that the launch has not affected the performance of Xtend-XMA.

Univ. of Maryland, Baltimore County (United States)
Dr. Tamura's major is X-ray astronomy, and he has conducted X-ray observations of supernova remnants and X-ray pulsars. In particular, he has focused on the development of instruments for satellites and balloons, especially X-ray optics. He has been involved in the development of the hard X-ray telescope on Hitomi and the development of X-ray telescopes for balloon experiments such as InFOCuS and NuSMIT.
He was involved in the ground calibration of the X-ray Mirror Assembly (XMA) onboard the X-ray astronomy satellite XRISM at NASA/GSFC, and has performed ground calibration of two XMAs using the 100-m X-ray beamline at NASA/GSFC.
