摘要：

A newly developed hybrid photo-multiplier (HPMT) was used to measure scintillation photoelectron yield N-phels(E) of well-known YAP:Ce and YAG:Ce scintillating crystals. N-phels(E) measured by the HPMT or evaluated LY(E) were compared with results obtained by the classical PMT. Generally, both crystals are characterized by roughly the same photoelectron and light yields which can reach up to 6400 phels/MeV or 24 000 ph/MeV, respectively. These yields were measured with cylindrical plates of shape circle divide 10 x 1 or 2 mm(3) under 662 keV gamma-ray radiation. The energy resolutions of both crystals at 662 keV are good and the best values reach congruent to4.6% or congruent to5.1% for YAP:Ce or YAG:Ce, respectively. (C) 2003 Elsevier B.V.
