Abstract Text:
The Tech-X fluid and MHD framework, Txfluids, is incorporated with new features relevant to magneto-inertial confinement fusion simulations. Txfluids is an easy-to-access, parallel, 3D code available to the ICF community. These new features include anisotropic heat conduction , laser ray tracing and energy deposition. Laser-driven magnetic-flux compression is an innovative approach to achieve magneto-inertial fusion (MIF). A cylindrical target with initial seed magnetic field is compressed by energetic laser beams. The magnetic field that is “frozen-in” plasma gets compressed with the target. The resulting high magnetic field reduces electron thermal conductivity and improves alpha particle confinement, thus providing an additional thermal insulation of the fuel forming the hot spot. It reduces the energy and driver symmetry requirements for ignition. We discuss our approach to determine the best algorithms for properly modeling laser-driven shock implosions with magnetic fields in conditions relevant to cylindrical MIF and benchmark magnetic compression with one-dimensional simulation.
