      abstract     = {The rapid progress in the field of laser particle
                      acceleration has stimulated a debate about the promising
                      perspectives of laser based ion beam sources. For a long
                      time, the beams produced exhibited quasi-thermal spectra.
                      Recent proof-of-principle experiments demonstrated that ion
                      beams with narrow energy distribution can be generated from
                      special target geometries. However, the achieved spectra
                      were strongly limited in terms of monochromacity and
                      reproducibility. We show that microstructured targets can be
                      used to reliably produce protons with monoenergetic spectra
                      above 2MeV with less than $10\%$ energy spread. Detailed
                      investigations of the effects of laser ablation on the
                      target resulted in a significant improvement of the
                      reproducibility. Based on statistical analysis, we derive a
                      scaling law between proton peak position and laser energy,
                      underlining the suitability of this method for future
                      applications. Both the quality of the spectra and the
                      scaling law are well reproduced by numerical simulations.},
