摘要：

Replacement of a quartz photocathode window by an YAlO3 (YAP) window yielded improved light transitions from EGO crystals (1.78 times) and PbWO4 crystals (1.76 times) to the photocathode. This improvement is due to the higher refractive index of YAP (1.95), which matches much better the indices of EGO (2.14) and PbWO4 (2.18) than quartz (1.47). (C) 1999 Elsevier Science B.V.
