Whole Device Modeling of the FuZE Sheared-Flow-Stabilized Z Pinch
I. A. M. Datta, E. T. Meier, U. Shumlak
The FuZE sheared-flow-stabilized Z pinch at Zap Energy is simulated using whole-device modeling employing an axisymmetric resistive magnetohydrodynamic formulation implemented with…
On the validity of quasilinear theory applied to the electron bump-on-tail instability
D. W. Crews, U. Shumlak
The accuracy of quasilinear theory applied to the electron bump-on-tail instability, a classic model problem, is explored with conservative high-order discontinuous Galerkin method…
Observation of fast current redistribution in an imploding plasma column
Christine Stollberg, Eyal Kroupp, Dimitry Mikitchuk +10
Spectroscopic measurements of the magnetic field evolution in a Z-pinch throughout stagnation and with particularly high spatial resolution reveal a sudden current redistribution f…
Time-discretization of a plasma-neutral MHD model with a semi-implicit leapfrog algorithm
Sina Taheri, Jacob R. King, Uri Shumlak
The semi-implicit leapfrog time-discretization is a workhorse algorithm for initial-value MHD codes to bridge between vastly separated time scales. Inclusion of atomic interactions…
Sustained neutron production from a sheared-flow stabilized Z-pinch
Y. Zhang, U. Shumlak, B. A. Nelson +11
The sheared-flow stabilized -pinch has demonstrated long-lived plasmas with fusion-relevant parameters. This Letter presents the first experimental results demonstrating sustain…
A Discontinuous Galerkin Method for Ideal Two-Fluid Plasma Equations
John Loverich, Ammar Hakim, Uri Shumlak
A discontinuous Galerkin method for the ideal 5 moment two-fluid plasma system is presented. The method uses a second or third order discontinuous Galerkin spatial discretization a…
