The acceleration of protons at few MV by TNSA is well established and the quality of beams is improving using structured targets. Reaching nergies between 100 and 200 MeV an is a very challenging goal, of interest for oncological therapy, but requires laser powers of 1 PW or more. An intermediate objective is the production of protons up to 10 MeV with a medium power laser to tailor the beam in order to inject it into a drift tube and a compact high field linac. Ultra-short proton bunches up 30-40 MeV are suitable for radiobiological studies an preclinical research. We explore this possibility by simulating the acceleration of a proton beam with our code ALaDyn and the transport by using codes developed at Bologna and Milano for beam dynamics with space charge. The present work is part of the design study of a facility PROMETHEUS to be installed at the nuclear laboratories of Montecuccolino of the University of Bologna.
