Using full-scale three-dimensional particle-in-cell simulation with account of quantum-electrodynamic (QED) effects, we determine the parameters of generated pairs such as total number, density and angular distribution. Two different interaction configurations are considered based on the focusing of six laser pulses (with parameters expected at XCELS laser facility) onto a solid target. The configurations are not optimal in terms of the parameters ultimately achievable at this facility but in turn are reliable and quite simple in terms of their practical feasibility. It is shown that even in these configurations it is possible to generate electron\u2013positron pairs with energies up to GeV, a total number of pairs exceeding 10<sup>11<\/sup> and an average density reaching 2\u00d710<sup>20<\/sup> cm<sup>\u20133<\/sup>. Generating electron\u2013positron plasma with such parameters opens possibilities of laboratory investigation of several astrophysical phenomena.<\/div>\n<div><\/div>\n<div class=\"around-button\"><b>Keywords:<\/b> electron\u2013positron pair production, Breit&#8211;Wheeler process, particle-in-cell simulation.<\/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>A.
