Abstract
As space agencies consider the next generation of large space telescopes, it is becoming clear that high performance Ultraviolet (UV) imaging will be a key requirement. High-performing CMOS image sensors that are optimised for UV detection performance 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 the large format CIS303 and CIS120 detectors from Teledyne e2v for three large focal planes covering the UV , u ′ and g ′ bands, respectively. Typically, silicon sensors have a very low quantum efficiency (QE) in the UV band between 150- 300 nm, and the 2d-doping technology from NASA/JPL will therefore be utilised to improve the 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. This paper covers the specification of radiation testing of the CIS303 and CIS120 detectors at the Open University, and characterisation of the QE-enhancing surface treatments.
