Fig. 2

a Proton energy distribution from the Thomson parabola (TPIE) diagnostic on a BL shot, with its inferred proton characteristic temperature Tp determined from a Maxwell-Boltzmann (MB) distribution fit. The time-of-flight (TOF) of protons from source to target (430 μm) is shown on a secondary x-axis. b Fitting of the dose measured in each layer (HD-1, HD-2, ...) of the RCF stack diagnostic on a SL shot with the dose deposited by a MB energy distribution, indicating inferred proton characteristic temperature and conversion efficiency (CE) from laser to protons for energies >1 MeV (extrapolated).
