【 摘 要 】

It is now experimentally proven that intense beams of protons are generated in interactionsbetween high power lasers and thin solid targets. The energy spectrum and divergence of such beamscan be measured with stack structured calorimeters based on Radiochromic films (RCF). However, inorder to provide useful information, RCF have to be calibrated by a relation between the radiationdose that hits them and the colour change consequently recorded. We report here an experimentperformed at the 9 MV Tandem accelerator of IFIN-HH, having as aim the calibration of two newRCF types: HD-V2 and MD-V3 produced by Ashland Inc. [1] to MeV protons. Although protoncalibration data exists in literature for HD-V2 [2,3], we found no references for calibration of MD-V3with this type of particles. Our method is able to provide a global view on the RCF response from thevariation of the radiation dose given by the angular dependence of the scattering cross-section of aproton beam on a thin target.
