Development of ATHENA mirror modules
Proceedings of SPIE(2017)
摘要
Silicon Pore Optics (SPO), developed at cosine with the European Space Agency (ESA) and several academic and industrial partners, provides lightweight, yet stiff, high-resolution x-ray optics. This technology enables ATHENA to reach an unprecedentedly large effective area in the 0.2- 12 keV band with an angular resolution better than 5". After developing the technology for 50 m and 20 m focal length, this year has witnessed the first 12 m focal length mirror modules being produced. The technology development is also gaining momentum with three different radii under study: mirror modules for the inner radii (R-min = 250 mm), outer radii (R-max = 1500 mm) and middle radii (R-mid = 737 mm) are being developed in parallel.
