| Abstract: | The sensitivity, linear absorption coefficient and derivation, repeatability for LiF thermoluminescence dosemeter (TLD) are measured using a standard γ ray 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 laser plasma. |
