The production of proton beams by ns low intensity pulsed excimer laser ablation of solid hydrogenated targets is investigated. The targets used were solid disks produced by compression of TiH2 and CaH2 powder. The ion emission was analyzed by the time-of-flight (TOF) technique using a Faraday Cup as ion collector. We performed preliminary studies on the produced plasma in free expansion mode and under an accelerating voltage up to 15 kV, for different laser fluence values. The TOF spectra deconvolution through Maxwell-Boltzmann shifted function permitted us to evaluate the plasma temperature, particle density, ion charge state distributions, proton and ion energy and their relative yield. Using these special targets, we were able to obtain protons, titanium and calcium ion beams with a kinetic energy of some tens of keV.
