Simulation Case Study of Gamma ray Production from Laser Solid Interactions at Ultrarelativistic Intensity
Abstract
The emission of multi-MeV (gamma ray) photons from the interaction of a high-powered laser with a tailored plasma target is studied using particle-in-cell simulations. The plasma and pulse characteristics that produce a bright -flare are described, and results from two state-of-the-art codes are presented. The maximum laser-to-gamma energy conversion efficiency obtained is 30 , which is consistent with published results. The mechanism responsible for such high-energy photons is also discussed.
