Caption
Results of a 2D PIC simulation for 16-layer LSG. Spatial profiles of the acceleration field (x− Ex) at successive times are stacked vertically, where x = 0 corresponds to the initial target position. Here, the profiles are displayed by adding n× 0.15 TVm−1, where nis an integer from 0 to 38, increasing with a time step of 0.08 ps. The profiles are averaged around the laser optical axis over the laser spot size. Blue and orange shades indicate the area where protons and carbon 6+ with the top 1% of the energy distribution are present, respectively. The time axis is displayed on the right, where t = 0 corresponds to the time the laser starts to penetrate through the target. The inset shows the evolution of the maximum proton energy (εp, blue) with the temporal profile of the laser intensity at x = 0 (black).
