TL;DR: The Sustained Spheromak Physics Experiment (SSPX) as discussed by the authors was a high-temperature (Te up to 0.5 keV), coaxial helicity injection (CHI) formed by coaxial helical injection, with plasma duration of a few milliseconds following the high-current formation stage.

TL;DR: In this article, the formation and decay of a spheromak plasma driven by a coaxial electrostatic plasma gun is simulated with three-dimensional, time-dependent, resistive magnetohydrodynamic NIMROD code.

TL;DR: In this article, the authors present an overview of the plasma diagnostics operating or planned for the sustained spheromak physics experiment device now operating at Lawrence Livermore National Laboratory (LLNL).

TL;DR: In this paper, negative current sheets with λ = {mu}{sub 0}j {center_dot} B/B{sup 2}reversed relative to the applied current were simulated and the current sheets are most intense inside the separatrix near the X-point of the mean-field spheromak.

TL;DR: The magnetic helicity balance between the helicity input injected by a magnetized coaxial gun, the rate of change in plasma helicity content, and helicity dissipation in electrode sheaths and Ohmic losses have been examined in the Sustained Spheromak Plasma Experiment (SSPX) as discussed by the authors.
