Acceleration rate enhancement by negative plasma density gradient in multi-bunch driven plasma wakefield accelerator

Accelerator Physics 2024-11-15 v1 Plasma Physics

Abstract

In a plasma wakefield accelerator driven by a train of short particle bunches, it is possible to locally increase the acceleration rate by introducing a small negative gradient of the plasma density. A regime is possible in which the gradient affects only the relative phasing of the driver bunches and the wave, keeping the wave phase behind the driver stable. With this technique, it is possible to increase the energy gain of the accelerated witness bunch in a plasma section of limited length.
