Abstract

Magnetic fields of the order of hundred of MG (10 kT) may relax ignition conditions for inertial confinement fusion (ICF) [1]. The nearly axial magnetic field generated by one or two coils can be strongly compressed in the laser-driven implosion of a spherical target, and increased neutron production has been reported [2, 3]. Recently, experiments on magnetized exploding pushers were performed [4]. Magnetized targets are also envisaged for fast ignition [5]. Such developments motivate the present work. We have upgraded our 2-D Lagrangian ICF code DUED [6, 7] by including models for magnetic field evolution and for the effects of the field on plasma and charged fusion product transport. In the following we outline the model and its solution, and present preliminary applications of the code.
