摘要
采用脱氧剂非真空坩埚下降法生长出的大尺寸PbF_2晶体具有优异的Cherenkov辐射特性,其透光截止波长最短可达245um,能量分辨率优于32%/,辐照损伤很弱,用365um的过滤光漂白后,透光能力几乎可以完全恢复到辐照之前的水平.
A large size PbF2 crystal was grown with the modified non-vacuum Bridgeman method. Itpossesses outstanding Cherenkov radiation properties. Its cut-off edge is as short as 245urn, theenergy resolution is superior to 3.2%/, and the radiation damage is weak and can be cured byannealing with 365um filtered light.
