Preliminary characterization of PRESAGE® for 3D dosimetry of 62 MeV proton beam

PRESAGE® has previously shown potential for 3D dosimetry of heavy particles. A new formulation has specifically developed for dosimetry of protons/heavy ions. This work provides a preliminary characterization the new formulation of PRESAGE® by measuring optical absorbance and dose response after irradiating by a 62 MeV proton beam for a dose range of 0.5 - 20 Gy. Results show linear dose response and the evolution over time of the optical density of the 3D dosimeter.4 page(s
