Characterization of a laser driven supra-thermal ion source — •Jan Riedlinger, Lars Torben Schwabe, Qëndresa Ibraimi, and Georg Pretzler — Institut für Laser- und Plasmaphysik, Heinrich-Heine-Universität Düsseldorf

Today’s laser systems achieve repetition rates up to 100 khz at pulse energies of 1 mJ and sub-10-fs durations. With these parameters, laser plasmas become viable ion sources for applications which require a small source size. We present the results of experiments performed with such a laser, reaching intensities up to 10¹⁷ W/cm² on the target surface. This interaction creates a high temperature plasma emitting bunched ions over a broad spectrum in the keV regime. Here, mostly bulk targets were used due to the nearly free choice of materials and high densities for an increased particle output. The talk gives an in-depth view into the ion emission in terms of its opening cone, ionization states and kinetic energies as well as the purposely designed diagnostics.
