In order to realize high performances and radiation resistant detectors, high quality and thick epitaxial layer were grown on a substrate and a Schottky diodes were then realized. These detectors were employed to probe the plasma generated with a 300 ps laser at intensity of 1016W/cm2 operating at PALS. They show a fast response and a high sensitivity to high energy ions. Metallic and polymeric thin films were irradiated and the produced plasmas were monitored in forward and backward directions. The analysis of the time-of-flight spectra evidences the emission of protons and ions at different energies. The spectra were deconvolved with a shifted Maxwell Boltzmann distribution. We detected protons in the energy range 1.2 - 3.0 MeV and heavy ions between 1.0 MeV up to 40 MeV. The results were compared with the ones obtained by Thompson Parabola Spectrometer.
