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. Aßmann, 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…
