dc.description.abstractEnThe generation of particle beams with high intensity lasers opens new domains of investigation both for fundamental and applied research. These beams are often characterised with radiochromic films (RCF) which provide information both on their energy and spatial distributions. However the optical response function of these films for protons depends on their precise composition and is not well known making it difficult to extract absolute information on the number of particles in the beam. Proton induced nuclear reactions in RCF produce radioactive elements. The analysis of these activities allows to determine in a completely independent way the energy distribution of the proton beams. Using the Monte Carlo simulation code Geant4, we have established the nuclear activation response functions for different stacks of RCF films and stacks of RCF films and copper foils. We will present our method based on the optical and nuclear activation responses of RCF and discuss the results obtained in the analysis of proton beams generated with the LULI 100 TW laser.
