We report a study of laboratory plasmas with density ($n_e$) and temperature ($T_e$) close to those of solar chromosphere and photosphere. The dense plasmas produced in supercritical fluids [Nature Commun. 12, 4630 (2021)] by ns laser pulse show blackbody emission spectra, which gives $T_e \sim 1$ eV. The Saha equation modified by ionization potential depression gives $n_e ~ 10^{21}$...
The X-ray Calibration Facility (XCF) at the University and INFN of Torino is dedicated to the calibration and characterization of X-ray detectors, sensible to position, energy and polarization.
The facility is focused on the study of the Gas Pixel Detectors [1] for x-rays polarimetry of astrophysical sources, developed at INFN-Pisa. Such detectors are the core of the detector units of the...
