A note on the experiment parameters for the non-resonant streaming instability: competition between left and right circularly polarized modes
Chun-Sung Jao, Sergei Vafin, Ye Chen +10
A non-resonant streaming instability driven by cosmic-ray currents, also called Bell's instability, is proposed as a candidate for providing the required magnetic turbulence of eff…
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…
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…
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…
Mitigation of the hose instability in plasma-wakefield accelerators
T. J. Mehrling, R. A. Fonseca, A. Martinez de la Ossa +1
Current models predict the hose instability to crucially limit the applicability of plasma-wakefield accelerators. By developing an analytical model which incorporates the evolutio…
Chirp mitigation of plasma-accelerated beams using a modulated plasma density
R. Brinkmann, N. Delbos, I. Dornmair +13
Plasma-based accelerators offer the possibility to drive future compact light sources and high-energy physics applications. Achieving good beam quality, especially a small beam ene…
The FLASHForward Facility at DESY
A. Aschikhin, C. Behrens, S. Bohlen +35
The FLASHForward project at DESY is a pioneering plasma-wakefield acceleration experiment that aims to produce, in a few centimetres of ionised hydrogen, beams with energy of order…
Wakefield-Induced Ionization injection in beam-driven plasma accelerators
A. Martinez de la Ossa, T. J. Mehrling, L. Schaper +2
We present a detailed analysis of the features and capabilities of Wakefield-Induced Ionization (WII) injection in the blowout regime of beam driven plasma accelerators. This mecha…
High-Quality Electron Beams from Beam-Driven Plasma Accelerators by Wakefield-Induced Ionization Injection
A. Martinez de la Ossa, J. Grebenyuk, T. Mehrling +2
We propose a new and simple strategy for controlled ionization-induced trapping of electrons in a beam-driven plasma accelerator. The presented method directly exploits electric wa…
