External injection plasma wakefield acceleration at FLASHForward — •Sarah Schröder1, 2 and on behalf of FLASHForward1 — 1Deutsches Elektronen-Synchrotron (DESY), Notkestrasse 85, 22607 Hamburg — 2Universität Hamburg, Mittelweg 177, 20148 Hamburg
Owing to high-gradient accelerating fields (>GV/m), plasma wakefield accelerators (PWFA) have the potential of significantly reducing size and costs of future high-average power accelerator facilities. Acceleration stability and beam quality are largely dependent on the interplay between the parameters of the injected bunch and the structure of the plasma wakefield. Precise control of the bunch profile is essential for maximising the energy transfer efficiency and preserving the energy spread. At FLASHForward, driver/witness bunch pairs of adjustable bunch length and separation are generated by collimators in a dispersive section. Here we present the capabilities of precision measurements at FLASHForward and the latest experimental results.
