Physics of Laser-Wakefield Accelerators (LWFA)
Johannes Wenz, Stefan Karsch
Intense ultrashort laser pulses propagating through an underdense plasma are able to drive relativistic plasma waves, creating accelerating structures with extreme gradients. These…
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…
Research towards high-repetition rate laser-driven X-ray sources for imaging applications
J. Götzfried, A. Döpp, M. Gilljohann +6
Laser wakefield acceleration of electrons represents a basis for several types of novel X-ray sources based on Thomson scattering or betatron radiation. The latter provides a high…
Quick X-ray microtomography using a laser-driven betatron source
A. Döpp, L. Hehn, J. Goetzfried +6
Laser-driven X-ray sources are an emerging alternative to conventional X-ray tubes and synchrotron sources. We present results on microtomographic X-ray imaging of a cancellous hum…
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…
Temporal evolution of longitudinal bunch profile in a laser wakefield accelerator
M. Heigoldt, S. I. Bajlekov, A. Popp +6
Due to their ultra-short duration and peak currents in the kA range, laser-wakefield accelerated electron bunches are promising drivers for ultrafast X-ray generation in compact fr…
