Investigation of the Scintillation Properties of Domestic BaF2(La) Crystal

  •  Institute of High Energy Physics,Academia Sinica,Beijing 1000391 Beijing Glass Research Institute 100062

  • BaF2(La) crystal has been grown with 1% mole of BaF3 doped in BaF2 and the scintillation properties of the new crystal have been investigated before and after a γ irradiation of 60Co source.The radiation resistance of the domestic crystal can be up to a dose of 106 rad.Comparing with a pure BaF2 scintillator,it was found that the fast component of the BaF2(La) scintillator was almost no change but its slow component was suppressed to a factor of 4.

Abstract: BaF2(La) crystal has been grown with 1% mole of BaF3 doped in BaF2 and the scintillation properties of the new crystal have been investigated before and after a γ irradiation of 60Co source.The radiation resistance of the domestic crystal can be up to a dose of 106 rad.Comparing with a pure BaF2 scintillator,it was found that the fast component of the BaF2(La) scintillator was almost no change but its slow component was suppressed to a factor of 4.
