MCTrans++: A 0-D Model for Centrifugal Mirrors
Nick R. Schwartz, Ian G. Abel, Adil B. Hassam +2
The centrifugal mirror confinement scheme incorporates supersonic rotation of a plasma into a magnetic mirror device. This concept has been shown experimentally to drastically decr…
An adjoint-based method for optimizing MHD equilibria against the infinite-n, ideal ballooning mode
Rahul Gaur, Stefan Buller, Maximilian E. Ruth +3
We demonstrate a fast adjoint-based method to optimize tokamak and stellarator equilibria against a pressure-driven instability known as the infinite- ideal ballooning mode. We…
GX: a GPU-native gyrokinetic turbulence code for tokamak and stellarator design
N. R. Mandell, W. Dorland, I. Abel +4
GX is a code for solving the nonlinear gyrokinetic system for low-frequency turbulence in magnetized plasmas, particularly tokamaks and stellarators. In GX, our primary motivation…
Microstability of tokamak equilibria
Rahul Gaur, Ian G. Abel, David Dickinson +1
High-power-density tokamaks offer a potential solution to design cost-effective fusion devices. One way to achieve high power density is to operate at a high value (the ratio o…
Three-Dimensional Inhomogeneity of Electron-Temperature-Gradient Turbulence in the Edge of Tokamak Plasmas
J. F. Parisi, F. I. Parra, C. M. Roach +15
Nonlinear multiscale gyrokinetic simulations of a Joint European Torus edge pedestal are used to show that electron-temperature-gradient (ETG) turbulence has a rich three-dimension…
An adjoint method for neoclassical stellarator optimization
Elizabeth Paul, Ian Abel, Matt Landreman +1
Stellarators are a promising route to steady-state fusion power. However, to achieve the required confinement, the magnetic geometry must be highly optimized. This optimization req…
