Spectroscopic analysis of proton-induced fluorescence from yttrium orthosilicate

The results of a 3-MeV-proton irradiation test on two yttrium orthosilicate doped with cerium (YOS:Ce) crystal samples are reported. The principle goal of this test was to determine the proton dose required to reduce the resulting YOS:Ce fluorescence light to half of its original value (half brightness dose) at ambient temperature and 150 degrees C. Results from this test will also provide basic information concerning potential changes in spectral composition and fluorescence peak widths for YOS:Ce at ambient temperature and 150 degrees C.<
