UV detectors for spectrographs of WSO-UV project

摘要

The WUVS (WSO-UV Ultra Violet Spectrographs) consists of two high resolution spectrographs (R = 50000) covering the Far-UV range of 115–176 nm and the Near-UV range of 174–310 nm, and a long-slit spectrograph (R = 1000) covering the wavelength range of 115– 305 nm. Significant progress in the CCD development gives a possibility to use back-illuminated CCD detectors with anti-reflection coating for observations in the UV. These detectors are under construction by e2v company (UK) based on their heritage of detectors production for numerous space missions including those for UV- and far-UV. The main parameters of WUVS detector subsystems are described.
