概要:In the shock injection mechanism of laser wakefield acceleration (LWFA), the position and the size of the electron injection domain are determined by the shock downramp. To make the accelerated beam controllable and tunable, the relation between the injected beam quality and the shock downramp is investigated by kinetic simulations via the Particle-in-cell (PIC) code. Furthermore, the passive mode of a plasma lens is studied via real geometry PIC simulations for its suitability for LWFA. An initially negative chirp in electron beam energy is shown to be instrumental in suppressing the unwanted growth in the relative energy spread of the electron beam during the passive lensing.
