摘要：

The quantum efficiency (QE) curves of five Philips XP2020Q photomultiplier tubes (PMTs), one Hamamatsu R2059 PMT, and a Na-Salicylate coated glass window were determined using a calibrated Thorn EMI 9426 PMT as a reference. The QE of XP2020Q PMTs at wavelengths smaller than 230 nm appears much better than the values specified by the manufacturer. Consequently, the often reported photon yield of 2000 photons/MeV for the fast component of the scintillation pulses from pure BaF2 crystals determined with this tube is overestimated. Our results, obtained by means of calibrated equipment and using 662 keV gamma-rays, yield a value of 1400 photons/MeV.
