EUVID — a compact, high-resolution imaging detector for the wavelength range [formula omitted

Abstract

The E xtreme UV I maging D etector EUVID consists of a compact “micro-channel-plate-wedge-and-strip anode” imaging system and corresponding data read-out electronics with 32 MB of memory. EUVID is suited for imaging in the wavelength range 20 ≤ λ ≤ 1200 A ̊ . The performance of this space-qualified, 2.5 kg detector system was measured in the FUV. We obtained a spatial resolution of about 70 μm over the full detector area of ∼ 7 cm 2. Image distortions are small and can easily be corrected for. Detector efficiency depends on the choice of photocathode and ranges between 50% in the FUV up to 90% in the EUV.
