We use as reference the design of the optics of the planned X-ray mission Advanced Telescope for High ENergy Astrophysics (ATHENA) which is designed as a single X-ray telescope populated with stacked SPO substrates forming mirror modules to focus X-ray photons. We show that is possible to simulate in detail the SPO pores and qualify the use of McXtrace for in-depth analysis of in-orbit performance and laboratory X-ray test results. <P />STAMPAenConference paper10.1117/12.22330602-s2.0-85003674238000387731500197https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9905/1/Simulating-x-ray-telescopes-with-McXtrace--a-case-study/10.1117/12.2233060.short2016SPIE.9905E..76FFIS/05 - ASTRONOMIA E ASTROFISICAScienze Fisiche Settori ERC (ERC) di riferimento::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
