We describe the use of a genetic algorithm to apply active feedback to a laser wakefield
accelerator at a higher power (10 TW) and a lower repetition rate (5 Hz) than previous work …

Control of the properties of laser-plasma-accelerated electron beams that were injected
along a shock-induced density downramp through precision tailoring of the density profile …

A plasma channel created by the combination of a capillary discharge and inverse
Bremsstrahlung laser heating enabled the generation of electron bunches with energy up to …

Interaction of relativistic electron beams with high power lasers can both serve as a
secondary light source and as a novel diagnostic tool for various beam parameters. For both …
