Sensor system development for the WSO-UV (World Space Observatory–Ultraviolet) space-based astronomical telescope

As part of a strategy to provide increasingly complex systems to customers, e2v is currently developing the sensor solution for focal plane array for the WSO-UV (World Space Observatory – Ultraviolet) programme, a Russian led 170 cm space astronomical telescope. This is a fully integrated sensor system for the detection of UV light across 3 channels: 2 high resolution spectrometers covering wavelengths of 115 – 176 nm and 174 – 310 nm and a Long-Slit Spectrometer covering 115 nm – 310 nm. This paper will describe the systematic approach and technical solution that has been developed based on e2v’s long heritage, CCD experience and expertise. It will show how this approach is consistent with the key performance requirements and the overall environment requirements that the delivered system will experience through ground test, integration, storage and flight.
