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…
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…
The lower hybrid wave cutoff: A case study in eikonal methods
A. S. Richardson, P. T. Bonoli, J. C. Wright
Eikonal, or ray tracing, methods are commonly used to estimate the propagation of radio frequency fields in plasmas. While the information gained from the rays is quite useful, an…
