Kirkpatrick-Baez silicon pore optics for high-angular-resolution hard x-ray telescope

On demand | Presented live 17 June 2024

Abstract

We present a concept of hard X-ray telescope that could realistically reach arc-second level angular resolution. The optics is based on Kirkpatrick-Baez (K-B) configuration realised with Silicon Pore Optics (SPO) technology. SPO has been developed for 20 years at cosine (The Netherlands) for the European Space Agency’s next generation large X-ray telescope, NewAthena. This technology provides all the elements to realise a high-angular-resolution K-B optics. In this configuration the plates only need a slight meridional curvature and are flat in the sagittal direction, which reduces drastically the stress they undergo, and consequently the formation of slope errors. SPO is well suited for K-B configuration as the ribs running along the plates block efficiently stray light. Without sagittal curvature, the K-B mirror modules can be designed for the very small grazing incidence required for reflectivity at high energies. This type of telescope could be well suited for solar physics or astrophysics as a complement to NewAthena.
