Description
Plasma acceleration exploits extreme electric fields created in a plasma by high-current beams or high-intensity laser pulses, to accelerate charged particles. In current studies we explore prospects for beam-driven plasma acceleration within FLASHForward project at DESY, by means of 3D particle-in-cell simulations with the code OSIRIS. In particular, various techniques of injecting particles into a beam-driven wake are being considered. It is demonstrated that injecting particles by using transitions in plasma density allows for trapping and acceleration of electron beams, with final low emittance and low slice energy spread. The parameters of the driver beam and the plasma correspond to the current design for future experiments. Various parameter scans were performed, investigating sensitivity of the injected beam qualities, such its as length, charge, energy spread, and correlations in phase-spaces, to initial parameters of the driver and the plasma ramp.
