Abstract: One order of magnitude energy enhancement of the target surface electron beams with central energy at 11.5 MeV is achieved by using a 200 TW, 500 fs laser at an incident angle of 72° with a prepulse intensity ratio of 5×10−6. The experimental results demonstrate the scalability of the acceleration process to high electron energy with a longer (sub-picosecond) laser pulse duration and a higher laser energy (120 J). The total charge of the beam is 400±20 pC(Keywords: Strong field laser physics, Plasmas, Particles, Femtosecond phenomena, Surface dynamics.Published in RUNG: 07.08.2018; Views: 4756; Downloads: 0This document has many files!
