Within the Laser Ion Generation, Handling and Transport (LIGHT) research project at GSI, laser-driven ion acceleration and beam shaping are explored, combining a target normal sheath acceleration (TNSA) proton source with conventional accelerator technology. For this investigation, an ion test beamline was built and protons were accelerated via the TNSA mechanism. Out of broad energy spectrum, protons with an energy of 8 MeV are selected using chromatic focusing of a pulsed solenoid and injected into an rf cavity. Through phase focusing, temporally compressed proton bunches below 0.5 ns (FWHM) were generated with up to 5x108 particles in a single bunch at a distance of 6 m from the source and focused with a second solenoid. These bunches were successfully used for proton imaging.
