摘要
用脱氧剂非真空环境下 Stockbager 方法生长未掺和掺 La 的 BaF_2晶体.测量块状晶体光学透射的^(60)Co 的10~6radγ辐照损伤效应,提供辐照过程中色心形成和辐照后短期恢复信息,经退火和乙醇抛光后晶体透射已完全恢复到未辐照前的值.
BaF_2,undoped and doped with lanthanum,were grown not in vacuum by Stockbagerprocess with deoxidant.Radiation damage effects due to optical transmission in bulk crystalswith ^(60)Co,10~6 rad gamma irradiation were measured.These measurements provided theinformation of color center formation during irradiation as well as the short term recovery afterradiation.The optical transmission can be almost completely recovered to pre-irradiation value,after annealing and then polishing with ethyl alcohol.
