摘要: 用γ标准源对LiF热释光探测器(TLD)的灵敏度因子、线性吸收系数、离散性、重复性进行了测定。在此基础上建立了电子质量阻止本领的修正模型,理论上计算出电子等效质量阻止本领,给出单能电子的注量。由LiF TLD阵列可测量激光等离子体相互作用中发射的超热电子能谱(能量-注量关系)。Abstract: The sensitivity, linear absorption coefficient and derivation, repeatability for LiF thermoluminescence dosemeter (TLD) are measured using a standard γray source. A model is built to correct mass stopping power of the electron. The equivalent mass stopping power of the electron is calculated theoretically using the corrected model. The electron fluence can be obtained from the effective stopping power. An array of LiF TLD can be used to measure the hot electrons energy spectrum emitting from laserplasma.
