abstract = "In a plasma wakefield accelerator driven by a train of short particle bunches, it is possible to locally increase the acceleration rate by slightly decreasing the plasma density and introducing its small negative gradient. There is a regime in which changing the density 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.",

N2 - In a plasma wakefield accelerator driven by a train of short particle bunches, it is possible to locally increase the acceleration rate by slightly decreasing the plasma density and introducing its small negative gradient. There is a regime in which changing the density 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.
