Abstract The interaction of relativistically intense lasers with opaque targets represents a highly non-linear, multi-dimensional parameter space. This limits the utility sequential 1D scanning experimental parameters for optimization secondary radiation, although to-date this has been accepted methodology due to low data acquisition rates. High repetition-rate (HRR) augmented by machine learning present valuable opportunity efficient source optimization. Here, an automated, HRR-compatible...
Abstract Laser-plasma acceleration of protons offers a compact, ultra-fast alternative to conventional techniques, and is being widely pursued for potential applications in medicine, industry fundamental science. Creating stable, collimated beam at high repetition rates presents key challenge. Here, we demonstrate the generation multi-MeV proton beams from fast-replenishing ambient-temperature liquid sheet. The has an unprecedentedly low divergence 1° (≤20 mrad), resulting magnetic...
