The fixed boundary plasma equilibrium basis for a one Gigawatt electric stellarator power plant
Samuel A. Lazerson, António J. Coelho, Dana Douqa +9
A fixed boundary stellarator equilibrium capable of producing 3 GW of fusion power (1 GW-electric) is presented as the design basis for the GIGA fusion power plant being developed…
Harnessing Toroidal Neutral Flows to Enhance Divertor Particle Exhaust
M. Moscheni, A. Herrmann, J. D. Lore +5
In 1991 Reiter et al. (1991 Plasma Phys. Control. Fusion 33 1579) considered the onerous exhaust requirements of ITER, and wrote: "The vacuum pumping problem of a fusion reactor wi…
Multi-Machine Scaling Laws for Fuel and Impurity Puffing Rates Sufficient for Detachment Access: a Systematic Review of Magnetic Confinement Fusion Devices
M. Moscheni, A. Herrmann, R. Kembleton +8
An open-source database of 457 experimental and numerical entries representing 32 machinesincluding tokamaks, stellarators, and linear plasma devicesis assembled. From this d…
Proof of concept of a fast surrogate model of the VMEC code via neural networks in Wendelstein 7-X scenarios
Andrea Merlo, Daniel Böckenhoff, Jonathan Schilling +7
In magnetic confinement fusion research, the achievement of high plasma pressure is key to reaching the goal of net energy production. The magnetohydrodynamic (MHD) model is used t…
Validating the ASCOT modelling of NBI fast ions in Wendelstein 7-X stellarator
S. Äkäslompolo, P. Drewelow, Y. Gao +37
The first fast ion experiments in Wendelstein 7-X were performed in 2018. They are one of the first steps in demonstrating the optimised fast ion confinement of the stellarator. Th…
Verification of the global gyrokinetic stellarator code XGC-S for linear ion temperature gradient driven modes
Michael D. J. Cole, Robert Hager, Toseo Moritaka +5
XGC (X-point Gyrokinetic Code) is a whole-volume, total-f gyrokinetic particle-in-cell code developed for modelling tokamaks. In recent work, XGC has been extended to model more ge…
