Description
High-intensity lasers can accelerate protons from solid targets via target normal sheath acceleration (TNSA). These beams possess short pulse durations and low emittance, with potential applications in radiobiology, radioisotope production and warm dense matter. However, their inherently large divergence (10’s of degrees) and the challenge of achieving multi-Hz operation need to be addressed. Building on a Gemini TA2 experiment in which proton focussing was observed in a low-density vapour from a liquid-sheet target, this presentation explores the impact of laser temporal shape, plasma profile and particle beam properties on proton beam size, presenting both simulation and experimental results.
