INFLUENCE OF DIFFERENT DETECTOR PARAMETERS ON THE NEUTRON SENSITIVITY OF OSL DETECTORS

Abstract On the basis of a method for the calculation of the neutron sensitivity of OSL detectors with a high content of hydrogen a systematic investigation of the influence of different detector parameters on the neutron sensitivity was carried out. The detector thickness, the thickness of the contact radiator, the luminophor contents and the grain size of the used luminophor influence the neutron sensitivity, first of all in the energy range of fast neutrons. Especially the use of small grain luminophor considerably increases the sensitivity whereas the other parameters have a small influence on the neutron sensitivity.
