 note = {Ultra-high intensities open a way towards Terawatt and potentially 
Petawatt gamma-ray pulses in the so called Gamma Flare regime. We 
performed our first experiment towards this regime with the J-KAREN-P 
laser operating at intensities close to 10^22 W/cm^2. In this 
presentation I will overview the experiment, including very bright hard 
x-ray generation (sub-MeV to a few-MeV spectral range), high-order 
harmonic generation (30 to 70 eV), and multiple additional diagnostics 
revealing information on preplasma (properties of reflected 1st, 2nd, 
and 3rd harmonics and back-reflection). I will compare these results 
with the integrated HD and PIC simulations., OPTO-2021 Symposium on Photon and Beam Science},
