Assessment of the reliability of deconvolution procedures for RCF spectroscopy of laser-driven ion beams

Abstract Laser-driven ion beams are defined by a number of unique features, including large spread in energy. A stack configuration radiochromic films (RCF) can be utilized to characterize such through measurements their energy spectra. spectroscopic procedure is reported that allows the proton density within each active layer film retrieved. This based upon on deconvolution algorithm developed Geant4 Monte Carlo simulations correct contributions depositions given layer. Through calculations, spectrum retrieved from simulated and compared with known spectrum, providing an examination efficacy this tool. Application thus offers potential correctly reconstruct incident laser-driven beam irradiated RCF.
