Electron-Scale-Driven Turbulence by Negative-Density-Gradient in NSTX
C. Clauser, J. Candy, J. Parisi +7
Gyrokinetic simulations of an NSTX spherical-tokamak plasma reveal novel negative-density-gradient (NDG) drift waves at electron-gyroradius-scale that drive turbulent transport com…
Doubling Fusion Power with Volumetric Optimization in Magnetic Confinement Fusion Devices
J. F. Parisi, J. W. Berkery, A. Sladkomedova +17
A technique, volumetric power optimization, is presented for enhancing the power output of magnetic confinement fusion devices. Applied to a tokamak, this approach involves shiftin…
Omnigenous stellarator equilibria with enhanced stability
Rahul Gaur, Rory Conlin, David Dickinson +7
To build an economically viable stellarator, it is essential to find a configuration that satisfies a set of favorable properties to achieve efficient steady-state nuclear fusion.…
Characterization of the ELM-free Negative Triangularity Edge on DIII-D
A. O. Nelson, L. Schmitz, T. Cote +18
Tokamak plasmas with strong negative triangularity (NT) shaping typically exhibit fundamentally different edge behavior than conventional L-mode or H-mode plasmas. Over the entire…
