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…
Intrinsic Stabilization of the Drive Beam in Plasma Wakefield Accelerators
A. Martinez de la Ossa, T. J. Mehrling, J. Osterhoff
The hose instability of the drive beam constitutes a major challenge for the stable operation of plasma wakefield accelerators (PWFAs). In this work, we show that drive beams with…
Temporal Feedback Control of High-Intensity Laser Pulses to Optimize Ultrafast Heating of Atomic Clusters
M. J. V. Streeter, S. J. D. Dann, J. D. E. Scott +27
We describe how active feedback routines can be applied at limited repetition rate (5 Hz) to optimize high-power TW) laser interactions with clustered gases. Optimization of…
Generation of quasi continuous-wave electron beams in an L-band normal conducting pulsed RF injector for laboratory astrophysics experiments
Ye Chen, Gregor Loisch, Matthias Gross +8
We report on an approach to produce quasi continuous-wave (cw) electron beams with an average beam current of milliamperes and a mean beam energy of a few MeV in a pulsed RF inject…
Direct Measurement of Focusing Fields in Active Plasma Lenses
J. -H. Röckemann, L. Schaper, S. K. Barber +17
Active plasma lenses have the potential to enable broad-ranging applications of plasma-based accelerators owing to their compact design and radially symmetric kT/m-level focusing f…
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…
