Grad-Shafranov equilibria via data-free physics informed neural networks
Byoungchan Jang, Alan A. Kaptanoglu, Rahul Gaur +3
A large number of magnetohydrodynamic (MHD) equilibrium calculations are often required for uncertainty quantification, optimization, and real-time diagnostic information, making M…
Phase-space entropy cascade and irreversibility of stochastic heating in nearly collisionless plasma turbulence
Michael L. Nastac, Robert J. Ewart, Wrick Sengupta +3
We consider a nearly collisionless plasma consisting of a species of `test particles' in 1D-1V, stirred by an externally imposed stochastic electric field. The mean effect on the p…
Kinetic-Ballooning-Limited Pedestals in Spherical Tokamak Plasmas
J. F. Parisi, W. Guttenfelder, A. O. Nelson +12
A theoretical model is presented that for the first time matches experimental measurements of the pedestal width-height Diallo scaling in the low-aspect-ratio high- tokamak NSTX…
