Abstract
For the next generation of large space telescopes, imaging in the UV band will be of high importance. UV optimisation technologies and high-performing CMOS image sensors will therefore be essential for these missions to be able to fulfil their science requirements. The CASTOR mission, a 1m UV space telescope project, will be utilising both the large format CIS303 and the CIS120 detectors from Teledyne e2v for three large focal planes covering the UV, u’ and g’ bands, respectively. With the UV band covering the 150-300nm wavelength range, the 2D-doping technology from NASA/JPL will be applied to improve quantum efficiency. The Open University will perform electro-optical testing and space qualification of the CIS303 and CIS120 detectors, including a comparison of different UV coating and enhancement technologies.

Dr. Jesper Skottfelt is a Research Fellow at the Centre for Electronic Imaging (CEI) at the Open University in the UK. He is primarily involved in detector simulation, characterization, and development for the UV, optical, and NIR wavelength range. He has been working on the radiation damage testing of the Euclid VIS detectors since 2015 with an emphasis on developing and defining the trap pumping method and is now leading the analysis of the trap pumping data that is being obtained as part of the in-orbit calibration routines for Euclid VIS. Additionally, Dr. Skottfelt is leading the work at the CEI to characterise and space-qualify the UV optimised detectors to be used for the Canadian CASTOR mission.
