Numerical modeling of magnetohydrodynamic activity in the Swarthmore Spheromak Experiment
Results from a three-dimensional axisymmetric resistive magnetohydrodynamic ~MHD! simulation are compared to experimental data from the Swarthmore Spheromak Experiment ~SSX! @M. R. Brown, Phys. Plasmas 6, 1717 ~1999!#. The MHD simulation is run under conditions and with dimensionless parameters similar to the experiment ~Lundquist number S51000, plasma beta b 50.1). The simulation is shown to r...
متن کاملEnergetic particles and magnetohydrodynamic activity in the Swarthmore Spheromak Experiment
Results from the Swarthmore Spheromak Experiment ~SSX! @M. R. Brown, Phys. Plasmas 6, 1717 ~1999!# indicate that formation and partial merging of two spheromak plasmas can be described well by a magnetohydrodynamic ~MHD! picture in which there is substantial evolution towards force free states within each vessel, while reconnection activity, also described reasonably well by MHD, occurs in the ...
متن کاملModeling Swarthmore spheromak reconnection experiment using hybrid code
A three-dimensional (3D) hybrid-particle model is developed for investigation of magnetic reconnection in the Swarthmore Spheromak Experiment (SSX). In this numerical model, ions are treated as fully kinetic particles, and electrons are treated as a massless fluid. The plasma responds to the electromagnetic fields in a self-consistent manner. The simulation is performed in a cylindrical domain....

متن کاملThree-dimensional MHD simulations of counter-helicity spheromak merging in the Swarthmore Spheromak Experiment
Recent counter-helicity spheromak merging experiments in the Swarthmore Spheromak Experiment (SSX) have produced a novel compact torus (CT) with unusual features. These include a persistent antisymmetric toroidal magnetic field profile and a slow, nonlinear emergence of the n = 1 tilt mode. Experimental measurements are inconclusive as to whether this unique CT is a fully-merged field-reversed ...
