The system can provide PW peak power at 0.1 Hz on target and can deliver short pulses with an energy of 30 J and pulse duration of 30 fs after compression with a contrast level of better than 1012. The current achieved laser intensity is up to ~5x1021 Wcm-2 with an energy of ~9 J on target. The interaction with a 5-μm stainless steel tape target provides electrons with a typical temperature of more than 10 MeV and energetic proton beams with typical maximum energies of > 40 MeV with good reproducibility. The protons are accelerated in the Target Normal Sheath Acceleration regime, which is suitable for many applications including as an injector into a beamline for medical use, which is one of our objectives.}, pages = {**--**}, title = {Ion acceleration experiment with the high intensity, high contrast J-KAREN-P laser system}, volume = {46}, year = {2018} }
