    This paper provides the first demonstration that an hydrogenated annealed crystalline silicon may be used as a source of protons in laser-driven acceleration experiments. We analyze and compare the proton production from two silicon targets excited by a sub-nanosecond laser. One target (treated) was hydrogenated and annealed, while the other (untreated) did not undergo these procedures. The experimental results show that for the treated target, the number of generated protons is ~1.4×10^15 sr−1 while for the other it is ~3.6×10^13 sr−1. Their maximum energy is about 2MeV with a laser intensity three order of magnitude lower than in previous experiments.
