The high efficiency of generating a record number of photons of multi-MeV energy with a huge peak gamma-ray flux is due to the use of the relativistic self-trapping of a laser pulse as a driver of such wake acceleration of electrons, which ensures the achievement of a maximum charge of multi-MeV of electrons and the maximum conversion efficiency of laser energy in near-critical density targets. The possibility of converting up to 8% of laser energy into the energy of a beam of gamma-ray photons (with an energy of more than 1 MeV) and the prospects for using the resulting source for deep gamma radiography in a single laser shot are demonstrated. The latter is also substantiated by a numerical experiment on obtaining gamma-ray images of dense hidden objects with a currently record-breaking shielding thickness (up to 400 mm of iron, which corresponds to a linear density of 320 g\u00b7cm<sup>\u20132<\/sup>) with good contrast (high spatial resolution).<\/div>\n<div class=\"around-button\"><b>Keywords:<\/b> laser electron source, bremsstrahlung, high-power gamma-ray pulses, deep gamma radiography.<\/div>\n<div><\/div>\n<div><b>Received:<\/b> 30.11.2022<br \/>\n<b>Accepted:<\/b> 30.11.2022<\/div>\n","protected":false},"excerpt":{"rendered":"<p>M.
