In-Orbit Background for X-ray Detectors

open access: yes, 2022
In-orbit background is an unavoidable feature of all space-borne X-ray detectors, and arises both from cosmic sources (diffuse or point-like) and from the interaction of the detectors themselves with the space environment (primary or secondary cosmic rays, geomagnetically trapped particles, activation of spacecraft structures). In this chapter the main
