Abstract

The Spektr-UF/WSO UV is a 1.7 m class ultraviolet observatory equipped with instrumentation for high spectral resolution and long slit low spectral resolution spectroscopy within a range of 115 and 315 nm. In addition, it is provided with an imaging instrument, the Field Camera Unit (FCU) composed by two independent channels: the near ultraviolet (NUV) channel operating at 174 and 305 nm, and the Far Ultraviolet (FUV) channel which can perform high resolution images and low dispersion spectra in the 115 to 176 nm spectral range. The detector for the FUV channel is provided by Spain, as part of its contribution to the project. Herein, the results of the qualification campaigns (quantum efficiency, photon counting uniformity, count rate linearity, spot uniformity, spatial stability or temporal uniformity) of the flight and spare detectors for the mission are presented.
