Abstract Text:
As a hybrid approach, Magneto Inertial Fusion (MIF) benefits from both the high energy density characteristic to ICF and the thermal insulation of the fuel by magnetic fields, typical for MFE. The reduction in thermal conduction losses in the hot spot of an imploding target that has trapped and amplified a pre-seeded magnetic flux, leads to increased hot-spot temperatures at lower implosion velocities, thus relaxing the energy requirements for ignition. This work describes the use of a compact magnetic pulse system to seed a macroscopic magnetic field into cylindrical DD-filled targets, which are radially driven with the OMEGA laser. The fusion yields are determined with the OMEGA suite of neutron diagnostics, while the simultaneous observation of the compression of the internal magnetic flux is done with proton deflectometry. Magnetohydrodynamic simulations predict compression of a 10T seed field to values of tens of megagauss. At such levels of magnetization, the radial electron thermal conduction in the hot spot is significantly inhibited. Results of the first series of experiments are shown and discussed.
