Simulating a pulsed power-driven plasma with ideal MHD

A. Beresnyak, A. L. Velikovich, J. L. Giuliani +4

We describe a simple practical numerical method for simulating plasma driven within a vacuum chamber by a pulsed power generator. Typically, in this type of simulation, the vacuum…

Modeling Intense-Electron-Beam Generated Plasmas Using a Rigid-Beam Approximation

A. S. Richardson, S. B. Swanekamp, N. D. Isner +6

A model of an electron-beam-plasma system is introduced to model the electrical breakdown physics of low-pressure nitrogen irradiated by an intense pulsed electron beam. The rapidl…

The rigid-beam model for simulating plasmas generated by intense electron beams

S. B. Swanekamp, A. S. Richardson, Tz. B. Petrova +1

We introduce a simplified model of the electron-beam/plasma system to model the electrical breakdown caused by the inductive electric field created by a rapidly rising electron bea…

Propagation speed, linear stability, and ion acceleration in radially imploding Hall-driven electron-magnetohydrodynamic shocks

A. S. Richardson, S. B. Swanekamp, S. L. Jackson +2

Plasma density gradients are known to drive magnetic shocks in electron-magnetohydrodynamics (EMHD). Previous slab modeling has been extended to cylindrical modeling of radially im…

Symplectic integrators with adaptive time steps

A S Richardson, J M Finn

In recent decades, there have been many attempts to construct symplectic integrators with variable time steps, with rather disappointing results. In this paper we identify the caus…

Quasi-separatrix layers and three-dimensional reconnection diagnostics for line-tied tearing modes

A. S. Richardson, J. M. Finn

In three-dimensional magnetic configurations for a plasma in which no closed field line or magnetic null exists, no magnetic reconnection can occur, by the strictest definition of…
