Abstract
The paper considers one of the most efficient methods for laser generation of a strongly magnetized hot plasma by means of ultra high power irradiation, achievable at the advanced XCELS facility. It is shown that the use of several pulses of the facility makes it possible to control the plasma parameters, while the energy efficiency, i.e., the ratio of the magnetic field energy to the total laser radiation energy, may reach ~20%. The resulting system with relativistic magnetized electrons and magnetic fields up to several tens of kT is of interest for laboratory studies of high-energy processes in astrophysics, in particular, the phenomenon of relativistic reconnection of magnetic field lines, as well as for various promising applications, e.g., for controlling flows of fast laser-accelerated particles.
