Abstract:

The effect of deep traps filled by a pulse electron beam on the thermoluminescent (TL) properties in Al2O3:C dosimetric crystals is studied. When the deep traps are filled, the dosimetric peak at 170 degrees C acquires a double-peak structure not present in the initial samples. The effect of the population of the deep centers having various nature (electron or hole traps) and energy depth on the shape of the dosimetric TL peak structure is analyzed. An assumption is made that in the temperature ranges of 350 500 degrees C and 650-750 degrees C, electron traps are emptied, whereas at T= 500-650 degrees C hole traps are emptied. The possibility of using the TL associated with deep traps in high-dose dosimetry of pulse electron beams is shown. (C) 2014 Elsevier Ltd. All rights reserved.
