Gyrokinetic Theory of Linear Gravitational Flute Interchanges with Flow Shear Stabilization
Zheng Yang Tan, Ian Abel
A collisionless electrostatic gyrokinetic theory is developed to describe how the presence of a differential velocity shear can help stabilize linear gravitational flute interchang…
First Observation of Dispersive Shock Waves in an Electron Beam
H. McCright, I. G. Abel, I. Haber +2
Dispersive shock waves (DSWs) are expanding nonlinear wave trains that arise when dispersion regularizes a steepening front, a phenomenon observed in fluids, plasmas, optics, and s…
Electrically insulating materials for centrifugal mirrors
Nick R. Schwartz, Carlos A. Romero-Talamás, Marlene I. Patino +10
The centrifugal mirror confinement scheme incorporates supersonic rotation into a magnetic mirror device, which stabilizes and heats the plasma. This concept is under investigation…
Machine-learning Closure for Vlasov-Poisson Dynamics in Fourier-Hermite Space
Nathaniel Barbour, William Dorland, Ian G. Abel +1
Accurate reduced models of turbulence are desirable to facilitate the optimization of magnetic-confinement fusion reactor designs. As a first step toward higher-dimensional turbule…
Forced 3D reconnection in an exponentially separating magnetic field
David N. Hosking, Ian G. Abel, Steven C. Cowley
We present a solvable scenario for 3D reconnection in a sheared magnetic field. We consider a localized external force that is applied slowly to a flux tube and then maintained, ge…
Effect of insulator end cap thickness on time-dependent Hartmann flow in a rotating mirror
Rahul Gaur, Ian G. Abel, Bindesh Tripathi +1
We present a framework for analyzing plasma flow in a rotating mirror. By making a series of physical assumptions, we reduce the magnetohydrodynamic (MHD) equations in a three-dime…
Global anomalous transport of ICRH- and NBI-heated fast ions
George J. Wilkie, Istvan Pusztai, Ian G. Abel +2
By taking advantage of the trace approximation, one can gain an enormous computational advantage when solving for the global turbulent transport of impurities. In particular, this…
