Abstract

The authors completed a 3 MeV proton irradiation test on a terbium gallium garnet crystal sample. The main goal was to determine the proton dose required to reduce the fluorescence intensity to half its original value (half-brightness dose) at ambient temperature. The 3 MeV proton half-brightness dose was found to be 1.25 × 1015 p/cm2 using the Birks and Black relation. This decay is comparable to other fluors irradiated by the authors. The sample exhibited a yellow glow when irradiated in a 3 MeV beam. The fluorescence spectrum was composed of four peaks at wavelengths of 487.2 nm, 542.4 nm, 589.92 nm, and 624.1 nm.
