Electromagnetic and geometric characterization of accelerated ion beams by laser ablation

► Pulsed lasers at intensities of the order of 108 W/cm2 and of ns pulse duration, interacting with solid matter in vacuum produce plasma of high temperature and density. ► A post-acceleration system, up to 160 kV of accelerating voltage, can be employed to increase the energy of the extracted ions from the plasma plume. ► A study of the electromagnetic and geometric properties, like emittance, of the beams delivered by pure Cu, Y and Ag solid targets has been performed. ► The electromagnetic characterization of the plasma was performed by a Faraday cup, whereas the geometric one by a pepper pot system.
