Acceleration rate enhancement by negative plasma density gradient in multi-bunch driven plasma wakefield accelerator
N. V. Okhotnikov, K. V. Lotov
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…
