WebHowever, it is insensitive to visible light and infrared. CsTe has a cutoff at 320 nm whereas CsI has a cutoff at 200 nm. Read more. View chapter Purchase book. ... Photoanode … Webthe sensitivity of the CsTe photocathode could be easily affected by tiny impurities and this is why such detectors should be made of carefully chosen materials and be carefully sealed. The long-term stability of such sealed detectors could be achieved only in low counting rate applications because at low rates the outgassing and aging are small.

Did you know?
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 WebPhotocathode is a key component to generate higher quality electron beam, thus we started to develop a Cs-Te photocathode as an electron source since 2007. Cs-Te photocathode shows high quantum efficiency (Q.E.) (~10 %) and has long life time (~several months). From 2013, we built a photocathode evaporation chamber and …

FIGS. 6A-6C depict graphs … 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
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). WebThe CsTe semitransparent photocathode is deposited on an Al 2O3 window. The outer Al 2O3 elements of B and C have a vacuum de-posited metallic grid for electrical shielding. The photodiode currents are amplified by an automatic four decade range-switching amplifier. The dynamic range is from 10-12 amperes, the minimum
WebCsTe photocathode, which is sensitive to the wavelength region from 120 to 310 nm. The heart of each MAMA detector is a microchannel plate (MCP) – a thin disk of glass approximately 1.5 mm thick and 5 cm in diameter that is honeycombed with small (12.5-micron) holes or pores. The front and back surfaces are metal coated. With a voltage
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.
