Abstract

The possibility to monitor pulsed dose-rate facilities by means of real-time fibered dosimetry is investigated. A system based on the luminescence of the SrS:Ce,Sm is used to monitor pulses from a medical accelerator with four different dose-rates. The RL signal is characterized using a dedicated acquisition system. The RL recorded is linear with dose-rate and dose. The stem effect due to both Cˇ erenkov emission and photoluminescence in the fiber was also investigated with 18 MV photons and 12 MeV electrons.
