Luminescent Dosimetric Materials Based on Magnesium Tetraborate for Proton Beam Metrology

The possibility of optical readout has been studied for the detectors based on MgB4O7:Dy,Na. It is shown that due to release electrons from traps instead holes under illumination by light, optically stimulated luminescence not observed, despite effective erasing thermally glow curves light. By analogy with MgB4O7:Tm, a model processes occurring during thermoluminescence presented.
