摘要
在BaF_2中掺入1％mol的LaF_3结晶出BaF_2(La)晶体,经测试,此晶体闪烁发光快成份的强度比纯BaF_2晶体不减弱,而发光慢成份被抑制约4倍,耐辐照能力可以达到10~6rad,表明新晶体有希望满足未来高能物理实验的要求。
BaF_2(La) crystal has been grown with 1% mole of LaF_3 doped in BaF_2 and the scintil-
lation properties of the new crystal have been investigated before and after a γ irradiation of
^(60)Co source. The radiation resistance of the domestic crystal can be up to a dose of 10~6 rad.
Comparing with a pure BaF_2 scintillator, it was found that the fast component of the BaF_2(La)
scintillator was almost no change but its slow component was suppressed to a factor of 4.
