 note = {We performed our first experiment on achieving ultra-high on-target intensities, reaching efficient conversion of laser radiation to hard x-rays ("Gamma Flash"), and generating intense coherent soft x-rays (high-order harmonics). Our joint team used the J-KAREN-P laser facility inat KPSI QST and irradiated solid targets with intensities close to 1022 W/cm2. We employed a broad range of diagnostics, including laser, plasma, secondary radiation (from NIR to MeV x-rays) and particle (e-, p+) diagnostics, and controlled preplasma using several laser contrast modes and artificial prepulse. In this presentation we overview the experiment and simulations dedicated to it, and show first results on hard x-ray and harmonic generation, x-ray spectroscopy, and preplasma analysis., 2020 Autumn JPS Meeting},
