Thanks to its wide field of view and good imaging capabilities, it will efficiently detect and localize gamma-ray bursts and other transients in the 2-150 keV sky, and also provide spectroscopy up to 10 MeV. Its current design has been optimized by means of scientific simulations based on a Monte Carlo model of the instrument coupled to a state-of-the-art description of the populations of long and short GRBs extending to high redshifts. We describe the optimization process that led to the current design of the XGIS, based on two identical units with partially overlapping fields of view, and discuss the expected performance of the instrument. | Conference Name: | Space Telescopes and Instrumentation 2020: Ultraviolet to Gamma Ray | Conference Place: | California, United States | Conference Date: | 14-18 December, 2020 | URI: | http://hdl.handle.net/20.500.12386/34533 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/11444/2560989/Scientific-simulations-and-optimization-of-the-XGIS-instrument-on-board/10.1117/12.2560989.short https://api.elsevier.com/content/abstract/scopus_id/85099283052 |
