Tunable and precise two-bunch generation at FLASHForward
S. Schröder, K. Ludwig, A. Aschikhin +17
Beam-driven plasma-wakefield acceleration based on external injection has the potential to significantly reduce the size of future accelerators. Stability and quality of the accele…
FLASHForward: Plasma-wakefield accelerator science for high-average-power applications
R. D'Arcy, A. Aschikhin, S. Bohlen +33
The FLASHForward experimental facility is a high-performance test-bed for precision plasma-wakefield research, aiming to accelerate high-quality electron beams to GeV-levels in a f…
A tunable plasma-based energy dechirper
R. D'Arcy, S. Wesch, A. Aschikhin +23
A tunable plasma-based energy dechirper has been developed at FLASHForward to remove the correlated energy spread of a 681~MeV electron bunch. Through the interaction of the bunch…
Analytical model for the uncorrelated emittance evolution of externally injected beams in plasma-based accelerators
Alexander Aschikhin, Timon Johannes Mehrling, Alberto Martinez de la Ossa +1
This article introduces an analytical formalism for the calculation of the evolution of beam moments and the transverse emittance for beams which are externally injected into plasm…
