Shock injection lwfa

Web10 Mar 2024 · A self-injection process via wave breaking or bubble expansion is commonly used in LWFA, but the stochastic characteristics of the self-injection process induce instability and degrade beam quality. As the acceleration structure used for LWFA is mostly on the scale of tens of microns [ 14 ], an electron bunch injection scheme with highly … Webthe injection point must be located after saturation of the the SMI. It is therefore natural so split the plasma into a self-modulation and an acceleration section. The relative phase of the wakeelds is expected not to change along the the acceleration plasma section. We consider placing a short (a few mm) gas-jet LWFA section driven by a multi-
