Betatron radiation enhancement by a density up-ramp in the bubble regime of LWFA
Original language description
We examine betatron radiation properties from the bubble regime of laser-wakefield acceleration for a tailored plasma density profile. Previous studies have already discussed enhancement of radiation properties by using various density modifications in later acceleration phases. This paper will focus on a density profile with a short linear up-ramp and compare it with a uniform density case. The process is studied for standard parameters feasible with current sub-100 TW laser systems by means of numerical particle-in-cell simulations. We show here that the critical energy and intensity of radiation increase when the plasma density increases. This enhancement is caused either by electron energy gain in the rear part of the bubble or by oscillation amplitude boost by fields behind the bubble.
