Description

The underdense photocathode "Trojan Horse" plasma wakefield acceleration is a promising technique for the generation of high-brightness and low-emittance witness bunches. It is shown that requirements on the driver electron beam can be substantially decreased by performing the witness beam generation on a soft density downramp, which facilitates trapping. As a consequence the underdense photocathode technique is applicable by a larger number of accelerator facilities and dark current is effectively suppressed.
