Generation of sub-nanosecond, intense proton bunches with the laser-driven LIGHT beamline and first imaging studies of a solid target — •Diana Jahn¹, Dennis Schumacher², Christian Brabetz², Johannes Ding¹, Rene Leonhardt¹, Florian-Emmanuel Brack^4,5, Florian Kroll^4,5, Abel Blazevic^2,3, Tom Cowan^4,5, Ulrich Schramm^4,5, and Markus Roth¹ — ¹TU Darmstadt, Darmstadt, Deutschland — ²GSI, Darmstadt, Deutschland — ³HI Jena, Jena, Deutschland — ⁴HZDR, Dresden, Deutschland — ⁵TU Dresden, Dresden, Deutschland

In the past two decades, the generation of intense ion beams based on laser-driven sources became an extensively investigated and promising field. The LIGHT collaboration combines a laser-driven proton source with conventional accelerator technology. Therefore, a laser-driven multi-MeV ion beamline at GSI Helmholtzzentrum für Schwerionenforschung was installed. Protons with an energy of 8 MeV are selected via chromatic focusing with a high-field solenoid from an exponentially decaying TNSA spectrum. Afterwards, they are injected into an rf cavity and temporally compressed through phase focusing into the subnanosecond regime. At the end of the beamline, a second solenoid was set up as a final focusing system. Newest focusing results and first imaging studies of a solid target will be presented.
