VUV AND ULTRASOFT X-RAY DIODE DETECTORS FOR TOKAMAK PLASMAS
Ultrasoft X-ray diode (USXRD) arrays have been used on D-IIID and ASDEX to study plasma edge radiation, in the photon energy range from 10 eV to 10 keV. The detectors are extremely useful and versatile due to their simplicity and compactness. Furthermore, absolute quantum efficiencies (QE) of many photocathodes such as vitreous C, Al, CuI, CsI and Au have been measured in recent years. With filter technique, broadband resolution, Ee-ltaEsim1, is possible. QE comparison of USXRD with semiconductor XRD is also presented to better understand the regions of applicability for each detector.
