When a high-intensity laser (IL ≥ 1018 W/cm2) strikes a solid target, the laser ionizes the material and couples its energy to the so-called hot electrons. Hard X-rays are subsequently emitted from the laser-target interaction mainly in a form of the braking (bremsstrahlung) radiation owing to the electrons scattering in the ions Coulomb field. Measurement and characterization of such photons are of strong interest since it can provide resourceful information about inner plasma processes (i.e. laser absorption, heat transfer) and help to determine key properties of other plasma byproducts (i.e. temperature, acceleration method). Here we present results obtained using a scintillator-array based calorimeter at ELI-Beamlines (Extreme Light Infrastructure) during the ELIMAIA user beamline (ELI Multidisciplinary Applications of laser-Ion Acceleration) commissioning, where a PW laser with intensities up to IL =1021 W/cm2 was applied on thin (µm) solid targets.
