内容記述 | The verifications of the irradiation field or dose distribution in the charged particle therapy require the measurements with high spatial resolution, because these distributions are precipitous and complex. Recently, it was reported that the commercial Al2O3 ceramics plate (Kyocera corp., A476) showed good TL characteristics and available as 2D dosimeter. This ceramic TLD was very easy to deal and low-cost device, and with high spatial resolution. In order to use this ceramic TLD in the charged particle therapy as the verification tools, we investigated the thermoluminescence characteristics of the ceramic TLD to charged particle beams. In this study, experiments of several charged-particle-beam irradiations were performed at the Heavy-Ion Medical Accelerator in Chiba (HIMAC) in the National Institute of Radiological Sciences (NIRS). The glow curve of the ceramic TLD was measured using a photon counting unit and programmable heat controller. The glow curves were recorded from room temperature up to 400 deg.C at a heating rate of 0.1 deg.C/s in air. The glow peaks were located at 148 deg.C, 220 deg.C and 285 deg.C. The dose linearity of all peaks was very good, but the TL efficiencies of each peak showed different LET dependence effect. The TL efficiency of the peak located at 148 deg.C showed remarkable small LET dependency. Using this TL-peak property, the commercial ceramics plate A476 might be available to measure dose distributions in charged particle therapy. | |||||
