WebNov 11, 2005 · The successful test of these detectors opens the possibility to build sealed large-area RPCs with CsTe photocathode, which could find many applications, for example, in RICH, spectroscopy, hyperspectroscopy, UV “radars”, flame detectors or time of flight BaF 2 PET (for more details see Ref. [12] and references therein). WebCsTe is originally developed byCERN[1] as the high QE cathode material. KEK-ATF and Nagoya university collab-orated to apply this material as the cathode in the photo-cathode RF gun. In ATF, this ...

Study of Cs-Te photocathode for rf electron gun
Webphotocathode has been reported by accelerators all over the world [5–10]. The popularity of CsTe as cathode material comes from its balanced properties between the high quantum efficiency (over 10% at its working wavelength), long lifetime (over a span of several months) and its robustness to chemical contamination and high gradient WebThe photocathode could also be deposited on a reflective metal surface, enabling very high instantaneous pulse currents ... In addition, the QE of CsTe at 11 eV (~150 nm) can be above 60% [7] and even higher shortward. In the present study an external mirror was always used to return light to the photocathode for a second pass and had a WebCsTe is the material of choice for a far UV semitransparent cathode, but it has fairly low efficiency (o20%), and cuts ... response, making it an attractive replacement for CsTe (and possibly CsI). 2.
