Thermoluminescent detectors measurements in critical mock-up: Monte-Carlo calculations of cavity phenomena

In the framework of the AMMON experimental programme, thermoluminescent detectors will be used to measure gamma doses in the EOLE facility. The aim of this work is to model the cavity phenomena related to the calibration of the TLD. Monte Carlo Simulation of coupled transport of electrons and gamma particles will be carried out to obtain cavities corrections of TLD, for calibration configuration. The results of cavity corrections, for all the TLD simulated, are close to one, which means that the thickness of the pill box selected is suitable for electronic equilibrium conditions.
