Low-temperature study of 35 photomultiplier tubes for the ZEPLIN III experiment
Araújo, H. M.; Bewick, A.; Davidge, D.; Dawson, J.; Ferbel, T.; Howard, A. S.; Jones, W. G.; Joshi, M.; Lebedenko, V.; Liubarsky, I.; Quenby, J. J.A set of 35 photomultiplier tubes (ETL D730/9829Q), intended for use in the ZEPLIN III Dark Matter detector, was tested from room temperature down to -100°C, with the aim of confirming their suitability for detecting xenon scintillation light at 175 nm while immersed in the cryogenic liquid. A general improvement of both gain and quantum efficiency at the xenon scintillation wavelength was observed with cooling...
