Abstract

In this paper, we report on the study of the optical properties of YAG:Ce and GGG:Ce garnet crystals after irradiation in a 660 MeV proton beam with a fluence up to 8.9 × 10¹⁴ protons/cm². We found that the transparency of both crystals fell by no more than 7% in the region of their own luminescence. The light yield of the YAG:Ce sample, measured one year after the irradiation, dropped by about 35%.

高通量质子束辐照的YAG：Ce和GGG：Ce闪烁晶体的光学性质

摘要

在本文中，我们报道了在660 MeV质子束辐照下，通量达8.9×10 ¹⁴质子/ cm ²的YAG：Ce和GGG：Ce石榴石晶体的光学性质的研究。我们发现，两种晶体在其自身发光区域内的透明度下降不超过7％。辐照一年后测量的YAG：Ce样品的光产率下降了约35％。
