摘要

本文报道了两块φ30×20BaF

晶体镀1.5mg/cm

对三联苯波长转换膜前后能量分辨率和时间分辨率的变化。采用RCA8850光电倍增管时

对三联苯能使能量分辨率明显变好;采用EMI9818 QKB光电倍增管时

能量分辨率稍变差。文中讨论了其原因。测得两块φ20×10BaF-2晶体镀1.6mg/cm

对三联苯后对

Coγ射线的时间分辨率为502ps。

Abstract

Properties of BaF2 crystals coated with or without P-terphenyl （a wavelength shifter） were studied. When crystals were mounted on the RCA 8850 PMTs

the use of the snifter resulted in a better energy resolution

but for EMI 9818 QKB PMTs

a worse result was obtained. The reason for these results was discussed. Time resolution measured for 60Co γ rays was 502 ps when two φ20×10 BaF2 crystals coated with 1.6 mg/cm2 P-terphenyl were coupled to RCA 8850 PMTs.
