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…
Impact of energetic alpha particles on core turbulence in an ARC-class fusion power plant
J. Hall, N. T Howard, P. Rodriguez-Fernandez +7
In this work, we investigate the impact of fusion-born alpha particles on core turbulence and transport in the ARC tokamak fusion power plant using linear and nonlinear gyrokinetic…
Non-dimensional confinement scaling in similar negative triangularity plasmas on the DIII-D and TCV tokamaks
A. Marinoni, C. Chrystal, S. Coda +25
Similarity experiments were performed on the DIII-D and TCV tokamaks to explore the scaling of energy confinement in negative triangularity plasmas using non-dimensional variables.…
Verification of Fast Ion Effects on Turbulence through Comparison of GENE and CGYRO with L-mode Plasmas in KSTAR
Donguk Kim, Taeuk Moon, Choongki Sung +7
This study presents a cross-verification of fast ion effects on turbulence through a systematic comparison of two leading gyrokinetic codes, GENE [F. Jenko et al., Phys. Plasmas 7…
Stable Deuterium-Tritium burning plasmas with improved confinement in the presence of energetic-ion instabilities
Jeronimo Garcia, Yevgen Kazakov, Rui Coelho +18
Providing stable and clean energy sources is a necessity for the increasing demands of humanity. Energy produced by fusion reactions, in particular in tokamaks, is a promising path…
Intrinsic rotation driven by non-Maxwellian equilibria in tokamak plasmas
M. Barnes, F. I. Parra, J. P. Lee +3
The effect of small deviations from a Maxwellian equilibrium on turbulent momentum transport in tokamak plasmas is considered. These non-Maxwellian features, arising from diamagnet…
Simulating Gyrokinetic Microinstabilities in Stellarator Geometry with GS2
J. A. Baumgaertel, E. A. Belli, W. Dorland +6
The nonlinear gyrokinetic code GS2 has been extended to treat non-axisymmetric stellarator geometry. Electromagnetic perturbations and multiple trapped particle regions are allowed…
