- Abstract
- Magneto-inertial concept to a fusion combines the advantages of magnetic and inertial confinement fusions and provides low-cost simple fusion schemes. Interest in research of magneto-inertial fusion (MIF) has recently been stimulated by (a) laser-driveт magnetic flux compression experiments, (b) the approach to a high β (beta is the ratio of plasma pressure to external magnetic pressure) magnetic systems. In our report we propose cusp configuration for the seeded magnetic field in laser driven MIF. Megagauss magnetic field generation in laser-driven plasma compression is studied. Magnetic field amplification during spherical laser implosion in such scheme may achieve > 1000. Advantages and difficulties of such a hybrid inertial-magnetic confinement approach are outlined. Various magnetic confinement schemes are considered and dynamics of high density plasma in strong magnetic fields is analyzed.
