Abstract
Pulsed nuclear irradiation of infrared window materials was performed at the TRIGA nuclear reactor. The pulse was 17 ms (FWHM) in duration, and the 0.1 Mrad dose consisted of 5% neutrons and 95% gamma rays. The samples under study included sapphire, CsI, ALON, and spinel. The radioluminescence exhibited by these samples during the irradiation was recorded and analyzed. Luminescence was observed in the 1.0-4.5 mu m range and in the visible range. The total emission over 1.0-4.5 mu m range was recorded with a PbSe detector with a cutoff wavelength of 4.5 mu m. Spectral information in the visible and near-infrared ranges was obtained with filters and with an optical multichannel analyzer. A kinetic model for radioluminescence was developed from the results.<>
