Self-Adaptive Stabilization and Quality Boost for Electron Beams from All-Optical Plasma Wakefield Accelerators
D. Campbell, T. Heinemann, A. Dickson +14
Shot-to-shot fluctuations in electron beams from laser wakefield accelerators present a significant challenge for applications. Here, we show that instead of using such fluctuating…
Physics of nanocoulomb-class electron beams in laser-plasma wakefields
J. Götzfried, A. Döpp, M. Gilljohann +7
Laser wakefield acceleration (LWFA) and its particle-driven counterpart, plasma wakefield acceleration (PWFA), are commonly treated as separate, though related branches of high-gra…
Nonlinear plasma wavelength scalings in a laser wakefield accelerator
H. Ding, A. Döpp, M. Gilljohann +6
Laser wakefield acceleration relies on the excitation of a plasma wave due to the ponderomotive force of an intense laser pulse. However, plasma wave trains in the wake of the lase…
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…
Dual-energy electron beams from a compact laser-driven accelerator
J. Wenz, K. Khrennikov, A. Döpp +10
Ultrafast pump-probe experiments open the possibility to track fundamental material behaviour like changes in its electronic configuration in real time. To date, most of these expe…
Quantitative X-Ray Phase-Contrast Microtomography from a Compact Laser Driven Betatron Source
J. Wenz, S. Schleede, K. Khrennikov +5
X-ray phase-contrast imaging has recently led to a revolution in resolving power and tissue contrast in biomedical imaging, microscopy and materials science. The necessary high spa…
Tunable, all-optical quasi-monochromatic Thomson X-ray source
K. Khrennikov, J. Wenz, A. Buck +4
Brilliant X-ray sources are of great interest for many research fields from biology via medicine to material research. The quest for a cost-effective, brilliant source with unprece…
Ultrasmall divergence of laser-driven ion beams from nanometer thick foils
J. H. Bin, W. J. Ma, K. Allinger +11
We report on experimental studies of divergence of proton beams from nanometer thick diamond-like carbon (DLC) foils irradiated by an intense laser with high contrast. Proton beams…
A Quantal, Partially Ordered Electron Structure as a Basis for a γFree Electron Laser (γ-FEL)
D. Habs, M. M. Günther, S. Karsch +2
When a rather cold electron bunch is transported during laser bubble acceleration in a strongly focusing plasma channel with typical forces of 100 GeV/m, it will form partially ord…
