Abstract
Replacement of a quartz photocathode window by an YAlO3 (YAP) window yielded improved light transitions from BGO 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 BGO (2.14) and PbWO4 (2.18) than quartz (1.47).
