Although extensive attempts have been carried out in around the world to produce better quality beams in a controllable manner in the past decades, there are still issues to be improved before realising many the applications. We have been investigating the ion acceleration performance from the irradiation of sub-micron solid density plastic and metal folis foils by using two different petawatt-class laser systems, J-KAREN-P at KPSI and Draco at HZDR, aiming at the optimizing ion acceleration performance in a controllable manner. We have achieved generated the energetic light ion acceleration (> 50MeV proton and > 30 MeV/u C6+) and the highly charged energetic heavy ions (Ag and Au) acceleration by controlling the laser temporal pulse condition. Hydrodynamic and 3D particle-in-cell simulation reveals that the laser temporal pulse shape plays an a vital role on in making tailored density conditions for the main pulse for theto undergo relativistic transparency, which as a result forms a transient space-charge field for the efficient ion accelerations. The robustness of the acceleration mechanism is confirmed by the similar ion acceleration performance achieved in the two laser systems. The results pave the way for the establishment of repetitive laser driven ion sources with high energy and high peak current applicable to radiobiology and material science., 光・量子ビーム科学合同シンポジウム2022}, title = {HIgh intenstiy laser dricen charged particle acceleration via relativistic transparency regime}, year = {2022} }
