We report on the J-KAREN-P laser facility at QST, which can provide PW peak power at 0.1 Hz on target. The system
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. Such performance in high field science will give rise to the birth of new applications and breakthroughs,
which include relativistic particle acceleration, bright x-ray source generation, and nuclear activation. The current
achieved laser intensity on target is up to > 9x1021 Wcm-2 with an energy of ~9 J on target. The interaction with a 3 to 5-
μm stainless steel tape target provides us 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.
