Abstract

Silicon Pore Optics (SPO) is a technology that makes it possible to build light-weight x-ray optics modules from silicon mirror plates using semiconductor industry technology and custom robots. By combining a large number of modules, the technology solves the problem of aperture segmentation and achieves a large collecting area with consistently high optical quality. Additionally, SPO is a highly adaptable technology that can be optimized for new applications beyond the Athena mission. Several applications have already been proposed for SPO, including Arcus Probe, a candidate probe-class mission that uses SPO modules in combination with transmission gratings to perform high-resolution spectroscopy. The Off-plane Grating Rocket Experiment (OGRE) uses SPO’s direct bonding techniques to align its reflection gratings to high accuracy. SPO has also been investigated in different optical designs, including x-ray interferometry. Furthermore, SPO technology can be used in Silicon Laue Components (SiLC) to focus hard x-rays and soft gamma rays in the energy range of 80 keV to about 500 keV. In conclusion, SPO technology is mature and can be mass-produced, enabling efficient adaptation to different needs. Its versatility and adaptability make it an excellent candidate for future x-ray astronomy missions and beyond.
