Compact Experimental Negative TriAngUlarity Reactor (CENTAUR): A design study for a compact, affordable breakeven tokamak
The CENTAUR Collaboration, Samuel W. Freiberger, Evan Bursch +33
This work presents the compact experimental negative triangularity reactor (CENTAUR), a low overnight cost, high-field tokamak, breakeven reactor design, achieving a predicted tota…
Tearing Stability Prediction Combining Toroidal Calculations With a Two-Fluid Slab Layer
D. A. Burgess, N. C. Logan, J. -K. Park +1
A new classical TM stability simulation workflow has been developed that solves the resistive inner-layer equations in a plasma slab to yield a linear, quasi-toroidal TM growth rat…
Variability of MHD Instabilities in Benign Termination of High-Current Runaway Electron Beams in the JET and DIII-D Tokamaks
C. F. B. Zimmermann, C. Paz-Soldan, G. Su +14
Benign termination, in which magnetohydrodynamic (MHD) instabilities deconfine runaway electrons (REs) following hydrogenic injections, is a promising strategy for mitigating dange…
ThinCurr: An open-source 3D thin-wall eddy current modeling code for the analysis of large-scale systems of conducting structures
Christopher Hansen, Alexander Battey, Anson Braun +5
In this paper we present a new thin-wall eddy current modeling code, ThinCurr, for studying inductively-coupled currents in 3D conducting structures -- with primary application foc…
Error Field Predictability and Consequences for ITER
Matthew Pharr, Nikolas Logan, Carlos Paz-Soldan +2
ITER coil tolerances are re-evaluated using the modern understanding of coupling to least-stable plasma modes and an updated center-line-traced model of ITER's coil windings. This…
Extending the trapping theorem to provide local stability guarantees for quadratically nonlinear models
Mai Peng, Alan Kaptanoglu, Chris Hansen +3
The Navier Stokes equations (NSEs) are partial differential equations (PDEs) to describe the nonlinear convective motion of fluids and they are computationally expensive to simulat…
Assessment of vertical stability for negative triangularity pilot plants
S. Guizzo, A. O. Nelson, C. Hansen +2
Negative triangularity (NT) tokamak configurations may be more susceptible to magneto-hydrodynamic instability, posing challenges for recent reactor designs centered around their f…
TokaMaker: An open-source time-dependent Grad-Shafranov tool for the design and modeling of axisymmetric fusion devices
C. Hansen, I. G. Stewart, D. Burgess +5
In this paper, we present a new static and time-dependent MagnetoHydroDynamic (MHD) equilibrium code, TokaMaker, for axisymmetric configurations of magnetized plasmas, based on the…
Design of Passive and Structural Conductors for Tokamaks Using Thin-Wall Eddy Current Modeling
A. F. Battey, C. Hansen, D. Garnier +5
A new three-dimensional electromagnetic modeling tool ThinCurr has been developed using the existing PSI-Tet finite-element code in support of conducting structure design work for…
Equilibrium reconstruction with 3D eddy currents in the Lithium Tokamak eXperiment
C. Hansen, D. P. Boyle, J. C. Schmitt +1
Axisymmetric free-boundary equilibrium reconstructions of tokamak plasmas in the Lithium Tokamak eXperiment (LTX) are performed using the PSI-Tri equilibrium code. Reconstructions…
