Laser pulse-electron beam synergy effect on electron self-injection and higher energy gain in laser wakefield accelerators

Abstract A new scheme for injection and acceleration of electrons in wakefield accelerators is suggested based on the co-action of a laser pulse and an electron beam. This synergy leads to stronger wakefield generation and higher energy gain in the bubble regime. The strong deformation of the whole...
