Abstract

With CMOS sensors starting to be utilised in astronomical telescopes, new uses for them are being explored. One such use is the possibility of observing distant, dim objects, which requires long integration times, and therefore low dark current. This work focuses on the dark current characterisation of the CIS220 at very long integration times at a range of temperatures, from +20 to –60 °C, before and after proton and gamma irradiation.
