Abstract Text:
A key question for plasma-jet Magneto-Inertial Fusion (MIF) is the achievable dwell time [1]. Various MIF cases with a target present will be presented and interpreted. These cases explore how well the liner's inertia provides transient plasma confinement. The resulting plasma parameters and fusion energy produced will be reported. The investigation uses UW's 1-D Lagrangian, radiation-hydrodynamics, burn-dynamics code, BUCKY, which solves single-fluid equations of motion with ion-electron interactions, PdV work, table-lookup equations of state, fast-ion energy deposition, and pressure contributions from all species. Extensions to the code include magnetic field evolution as the plasmoid compresses plus dependence of the thermal conductivity on the magnetic field. Preliminary results indicate that dwell times on the order of one microsecond are attainable with reasonable input energies for the plasma jets.
