The ion acceleration study is based on target normal sheath acceleration (TNSA) by irradiating several hundreds TW laser pulses onto foil targets. By carefully adjusting contrast level of our laser system J-KAREN-P, the maximum proton energy reaches to ~ 50 MeV now (Mar. 2017) with a 2-µm-thick Al target. We also improved the focal spot quality and the current strehl ratio measured on target is ~ 0.5 achieving~8.4x10^21 W/cm^2]. The electron acceleration study is conducted using J-KAREN-P laser and a smaller system JLITE-X at KPSI-QST. We are developing plasma and electron real time monitors and testing an electron acceleration with our J-KAREN-P laser. As for plasma monitors, we have developed sub-10-fs shadowgraph for direct plasma density modulation and holography for interferometric measurement. In addition, we have demonstrated characterization of pulse duration and timing of electron beams using electro-optic (EO) techniques., Laser Plama Accelerators 2017 IBS CONFERENCE参加、招待講演を行うとともに、最新の成果の調査及び研究者との交流・情報交換を行う}, title = {Laser Accelerator Development at KPSI-QST}, year = {2017} }
