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…
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…
Energy-chirp compensation in laser wakefield accelerators
A. Döpp, C. Thaury, E. Guillaume +7
The energy spread in laser-wakefield accelerators is primarily limited by the energy-chirp introduced during the injection and acceleration processes. Here we propose and demonstra…
Measurement of transverse wakefields induced by a misaligned positron bunch in a hollow channel plasma accelerator
C. A. Lindstrøm, E. Adli, J. M. Allen +18
Hollow channel plasma wakefield acceleration is a proposed method to provide high acceleration gradients for electrons and positrons alike: a key to future lepton colliders. Howeve…
High-charge relativistic electron bunches from a kHz laser-plasma accelerator
Dominykas Gustas, Diego Guénot, Aline Vernier +5
We report on electron wakefield acceleration in the resonant bubble regime with few-millijoule near-single-cycle laser pulses at a kilohertz repetition rate. Using very tight focus…
A bremsstrahlung gamma-ray source based on stable ionization injection of electrons into a laser wakefield accelerator
A. Döpp, E. Guillaume, C. Thaury +11
Laser wakefield acceleration permits the generation of ultra-short, high-brightness relativistic electron beams on a millimeter scale. While those features are of interest for many…
