Abstract

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, Y3 Al5 O12: Ce powder stiffened with a binder, and Y3 Al5 O12: Ce ceramics sintered at high temperature. The ion beam flux in the range from 1012 to 1013 ions (cm2 s) 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 Y3 Al5 O12: Ce with a binder and that sintered. Their applications to ITER lost alpha diagnostics are discussed.
