Characterization of a lobster-eye type X-ray telescope [PDF]

EPJ Web of Conferences, 2022
Lobster-eye type X-ray telescopes use reflecting plano mirrors under grazing incidence and can observe a large field of view. As part of a Bavarian-Czech cooperation, two telescopes were build, equipped with mirrors coated with gold and iridium.
