Direct observation of plasma waves and dynamics induced by laser-accelerated electron beams
M. F. Gilljohann, H. Ding, A. Döpp +14
Plasma wakefield acceleration (PWFA) is a novel acceleration technique with promising prospects for both particle colliders and light sources. However, PWFA research has so far bee…
Interferometric optical signature of electron microbunching in laser-driven plasma accelerators
A. H. Lumpkin, M. LaBerge, D. W. Rule +10
We report observations of coherent optical transition radiation interferometry (COTRI) patterns generated by microbunched ~200-MeV electrons as they emerge from a laser-plasma acce…
Hybrid LWFA PWFA Staging as a Beam Energy and Brightness Transformer : Conceptual Design and Simulations
A. Martinez de la Ossa, R. W. AÃmann, R. Bussmann +16
We present a conceptual design for a hybrid laser-to-beam-driven plasma wakefield accelerator. In this setup, the output beams from a laser-driven plasma wakefield accelerator (LWF…
On the observability of field-assisted birefringent Delbrück scattering
N. Ahmadiniaz, M. Bussmann, T. E. Cowan +3
We consider the scattering of an x-ray free-electron laser (XFEL) beam on the superposition of a strong magnetic field with the Coulomb field …
Stable and high quality electron beams from staged laser and plasma wakefield accelerators
F. M. Foerster, A. Döpp, F. Haberstroh +24
We present experimental results on a plasma wakefield accelerator (PWFA) driven by high-current electron beams from a laser wakefield accelerator (LWFA). In this staged setup stabl…
Restoring betatron phase coherence in a beam-loaded laser-wakefield accelerator
A. Köhler, R. Pausch, M. Bussmann +7
Matched beam loading in laser wakefield acceleration (LWFA), characterizing the state of flattening of the acceleration electric field along the bunch, leads to the minimization of…
Probing Ultrafast Magnetic-Field Generation by Current Filamentation Instability in Femtosecond Relativistic Laser-Matter Interactions
G. Raj, O. Kononenko, A. Doche +28
We present experimental measurements of the femtosecond time-scale generation of strong magnetic-field fluctuations during the interaction of ultrashort, moderately relativistic la…
Demonstration of a compact plasma accelerator powered by laser-accelerated electron beams
T. Kurz, T. Heinemann, M. F. Gilljohann +22
Plasma wakefield accelerators are capable of sustaining gigavolt-per-centimeter accelerating fields, surpassing the electric breakdown threshold in state-of-the-art accelerator mod…
