Description
In this paper, we present the experimental setup for measuring proton-induced luminescence with a fabricated scintillating glass. The glass was synthesized based on barium-gadolinium-fluoroborate glasses using the quenching technique. The luminescence generated by X-ray excitation of the glass demonstrates that an emission band centers around 400 nm owing to the Ce3+ by 5d–4f transition. Furthermore, the proton-induced luminescence experiment was set up to investigate light emission from the glass irradiated by a proton beam at King Chulalongkorn Memorial Hospital (KCMH), Bangkok, Thailand. The beam was operated with an energy of 70 MeV and an absorbed dose of 2,500 MU. A virtual water phantom was put in front of the glass with different thicknesses to observe the position of a Bragg peak. The energy deposition of the proton beam onto the glass scintillator was calculated by using the Gate simulation and compared with light emission from experimental results. We found that the position of the Bragg peak from the experiment and that of the simulation are consistent. According to the measured glass properties, the fabricated scintillating glass is suitable for being applied as a radiation detector or in other applications.
