对从氦到氙离子的几种离子束，对LiF：Mg，Ti和LiF：Mg，Cu，P的相对U效率进行了评估。辐射是在日本千叶的HIMAC加速器上实现的，部分是在ICCHIBAN相互比较项目中实现的。两种热释光探测器的相对响应度都随着电离密度的增加而减小，其中LiF：Mg，Cu，P探测器的相对响应度更强。效率和LET之间的关系被发现遵循独特的趋势线，因为几乎所有的数据点都在拟合的经验函数周围5%的范围内。对不同批次的同类型热释光二极管的热释光效率的测量结果在几个百分点以内。测量的相对热释光效率和LET之间的关系将用于分析从空间剂量学实验获得的数据。(C)2010爱思唯尔有限公司。保留所有权利。
The relative U efficiency of LiF:Mg, Ti and LiF:Mg, Cu, P was evaluated for several ion beams, ranging from helium to xenon ions. Irradiations were realized at the HIMAC accelerator in Chiba, Japan, partly within the ICCHIBAN intercomparison project. The covered LET range was extending from about 2 keV/mu m to 1500 keV/mu m.Both tested TLD types exhibited a decrease of relative response with increasing ionization density - stronger for LiF:Mg,Cu,P detectors. The relationship between efficiency and LET was found to follow unique trend lines, as nearly all data points lied within 5% around the fitted empirical functions. Values of TL efficiency measured for various batches of same type TLDs agree within a few percent. The measured relationships between relative TL efficiency and LET will be used in the analysis of data obtained from space dosimetric experiments. (C) 2010 Elsevier Ltd. All rights reserved.
