Stable bunch trains for plasma wakefield acceleration
arXiv:1711.07633 · doi:10.1088/1361-6587/aa9f97
Abstract
A train of short charged particle bunches can efficiently drive a strong plasma wakefield over a long propagation distance only if all bunches reside in focusing and decelerating phases of the wakefield. This is shown possible with equidistant bunch trains, but requires the bunch charge to increase along the train and the plasma frequency to be higher than the bunch repetition frequency.
