EVALUATION OF HYDRODYNAMIC INSTABILITIES IN INERTIAL CONFINEMENT FUSION TARGET IN A MAGNETIC FIELD

Magneto-inertial fusion (MIF) or inertial confinement fusion with magnetized target implosion is considered. Laser-driven MIF allows to compress the preseeded magnetic field to thousands of teslas. Model of high pulse energy laser target interaction is presented. Richtmyer-Meshkov (R-M) instability is investigated for MIF systems. We have shown that there is a possibility to suppress the R-M instability by magnetic field. Modeling the impact of magnetic field on a single plasma jet formed at the ICF laser target compression is performed. It is shown that at the compression and heating of a plasma target by using a rapidly growing external magnetic field and laser radiation the R-M instability can be suppressed.
