As an example, the regime of laser\u2013plasma interaction is studied at a moderately relativistic heating-pulse intensity of \u223c10<sup>18<\/sup> W\u00b7cm<sup>\u20132<\/sup> in a sufficiently large volume of a microcluster medium, which does not require tight focusing of a high-power laser beam (beams), thereby simplifying the experiment. If it has already been shown previously that for a laser pulse with an energy of \u223c1 J, under certain conditions for the geometric and compositional parameters of a deuterium-containing cluster target, it is possible to maximize the yield of hot superponderomotive electrons and explosively accelerated deuterons, then here the approach is extended to a femtosecond laser driver with an energy hundreds of times greater (300\u2013400 J). Recommendations are given for obtaining a record number of laser-heated deuterons of moderate energies (0.2\u20132 MeV) in a large volume of a cluster medium (heavy water spray) at a level of 10<sup>15<\/sup> particles per shot and for developing a superbright source of thermonuclear DD neutrons with an expected peak flux of \u223c10<sup>18<\/sup> neutrons\u00b7cm<sup>\u20132<\/sup>\u00b7s\u00b7<sup>\u20131<\/sup>.<\/div>\n<div class=\"around-button\"><b>Keywords:<\/b> multipetawatt lasers, large-volume transparent microstructured media, laser acceleration of electrons and deuterons, superbright sources of thermonuclear neutrons.<\/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>D.
