Characterization of Energetic Protons Generated in the ShenGuang-II UP Petawatt Laser Interactions with Foil Targets
Figure 3
(a) Proton images on RCF layers for the same shot as in Figure 2(a). (b) Proton energy spectrum derived from (a), which was fitted with Boltzmann distribution. (c) Divergence angle of the protons. The results from VULCAN and 100TW-LULI lasers by Nürnberg et al. [26] are used for comparison.
