 note = {We present an overview of our first joint experiment devoted to 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 (harmonics). We used the J-KAREN-P laser facility (KPSI QST) and irradiated solid targets with intensities approaching 10^22 W/cm^2. To get information on the interaction physics, we employed a broad range of diagnostics, including laser, plasma, secondary radiation (from NIR to MeV x-rays) and particles (e-, p+) diagnostics, and controlled preplasma using several laser contrast modes and additional artificial prepulse. We show first results on hard x-ray and harmonic generation, x-ray spectroscopy, and preplasma analysis.

We thank the J-KAREN-P laser operation group. We acknowledge financial support from ELI-Beamlines, JSPS JP 19H00669, and QST Director Funds 創成的研究 16 and 創成的研究 20., 2020 Annual (75th) JPS Meeting},
