DOIAbstract
International audienceThe response of EBT3 radiochromic film to ionizing radiation has been investigated for alpha beams. An experiment has been performed at the ARRONAX cyclotron to measure the net optical density (net OD) of EBT3 films as a function of the deposited doses of an alpha beam at different energies. A stack of 4 films was irradiated, therefore the beam energy is changed as a function of the film position between 45 MeV and 22 MeV. No differences in the film responses were observed in function of the alpha beam energy. The same calibration (Dose vs net OD) can be used for EBT3 film in this range of alpha beam energy. It is necessary to extend this study at lower energy down to the Bragg peak region
