本文测量了三种不同结构的发光材料：ZnS：Ag沉积在玻璃板上，Y_3Al_5O_（12）：Ce粉末用粘结剂加固，Y_3Al_5O_（12）：Ce陶瓷高温烧结，在高离子通量下的光输出特性。采用1012 ~ 1013闪烁离子（cm ~ 2·s）的离子束流辐照模拟燃烧等离子体实验。长时间的离子辐照使光输出下降。ZnS：Ag沉积闪烁体的劣化最为严重。Y_3Al_5O_（12）：Ce陶瓷在添加粘结剂和烧结后的劣化得到改善。讨论了它们在ITER损失α诊断中的应用。
The characteristics of light output by ion beam irradiations under high ion fluxes have been measured for three kinds of scintillators: ZnS:Ag deposited on the glass plate, Y3Al5O12:Ce powder stiffened with a binder, and Y3Al5O12:Ce ceramics sintered at high temperature. The ion beam flux in the range from 1012to1013ions∕(cm2s) is irradiated to simulate the burning plasma experiments. The decrease of light output has been observed by long time ion irradiation. The deterioration of ZnS:Ag deposited scintillator is most serious. The deterioration has been improved for the scintillators of Y3Al5O12:Ce with a binder and that sintered. Their applications to ITER lost alpha diagnostics are discussed.
