Laser Driven Electron Acceleration from Near-Critical Density Targets towards the Generation of High Energy <i>γ</i>-Photons
In this paper, we investigate the production of high energy gamma photons at the interaction between an ultra-high intensity laser pulse with an energetic electron beam and with a near-critical density plasma for the laser intensity varying between <inline-formula><math xmlns="http://w...
