at al., Simulations of 25 GeV PWFA sections: path towards a PWFA Linear Collider, in these proceedings

Recent Plasma Wake-Field Acceleration (PWFA) exper-iments at Stanford Linear Accelerator Center has demon-strated electron acceleration from 42 GeV to 84 GeV in less than one meter long plasma section. The accelerating gra-dient is above 50 GeV/m, which is three orders of magnitude higher than those in current state-of-art RF linacs. Fur-ther experiments are also planned with the goal of achiev-ing acceleration of a witness bunch with high efficiency and good quality. Such PWFA sections with 25 GeV en-ergy gain will be the building blocks for a staged TeV electron-positron linear collider concept based on PWFA (PWFA-LC). We conduct Particle-In-Cell simulations of these PWFA sections at both the initial and final witness beam energies. Theoretical analysis of the beam-loadin
