Magnetic Nozzle Studies on the Bryn Mawr Experiment

The Bryn Mawr Experiment (BMX) investigates the magnetic turbulence of toroidal plasma structures formed within a flux conserving cylindrical chamber. The BMX generates these compact tori via an internal coaxial plasma gun source. An internal coil creates a stuffing flux within the gun source, and two outer coils are implemented in a magnetic nozzle configuration. Modeling of the nozzle in COMSOL Multiphysics is presented, and the responses of the plasma structures’ bulk speed to parametric sweeps on BMX – energy injection, nozzle field strength, stuffing flux strength, and density – are presented and explored.
