摘要

用LiF（M，Ti）热释光剂量计测量了兰州重离子研究装置提供的49．3MeV／u12C离子束辐射的剂量响应．结果发现，离子注量在1×107－2×108／cm2时，LiF对碳离子束的剂量响应效率η变化幅度不大，平均值为57％。提示LiF可用于一定离子注量范围内吸收剂量的测量，并且该结果与德国GSI通过重离子径迹结构理论模型计算得到的热释光剂量计对50MeV／u12C离子束的η＝54％基本一致。

Abstract

LiF(Mg

Ti) thermoluminescence dosimeter (TLD) was applied to measure dose response to irradiation of 49.3MeV/u 12C ion beam supplied by HIRFL. Moderate variance of dose-response efficiency was found when particle fluence increases from 1×107 to 2×10 8/cm2 . The average dose-response efficiency 57% was obtained. This phenomenon implies that LiF can be used to measure absorbed dose in a certain range of particle fluence . Moreover

the result is in a good agreement with the calculated dose-response efficiency 54% to 50MeV/u 12C ion beam

which was predicted by the model of heavy-ion track structure at GSI

Germany.
