Development of a diamond detector for temporal profile measurements of intense, short ion bunches within the LIGHT project — •Diana Jahn1, Michael Träger2, and Mladen Kis2 for the LIGHT collaboration — 1Technische Universität Darmstadt — 2GSI Helmholtzzentrum für Schwerionenforschung
In the context of 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. In the LIGHT experimental campaign in 2015, protons were accelerated via the TNSA mechanism, an energy of 7.8 MeV was selected and collimated with a pulsed solenoid and injected into a rf cavity. Through phase focusing, temporally compressed proton bunches were generated to a pulse length of <240 ps (FWHM) with up to 5×108 particles in a single bunch at a distance of 6 m from the source. An ultrafast diamond detector has been specially developed to measure the temporal profile of these bunches and will be presented.
