Generation of Strong Magnetic Fields in Cylindrical Shell Targets by an Intense Circularly Polarized Laser Pulse

Abstract

Based on analytical estimates and numerical simulation, we consider the generation of a superstrong magnetic field by a circularly polarized laser pulse in a laser target shaped as a hollow cylinder with a radius of a fraction of a micrometer. The amplitude and lifetime of the magnetic field in this target is shown to additionally increase due to the compression of the cylinder.
