Reduction of transport due to magnetic shear in gyrokinetic simulations of the scrape-off layer
N. R. Mandell, G. W. Hammett, A. Hakim +1
The effect of varying magnetic shear on scrape-off layer turbulence and profiles is studied via electromagnetic gyrokinetic simulations of a helical scrape-off layer model. We deve…
Overstability of Plasma Slow Electron Holes
I H Hutchinson
Sufficient conditions are found on the ion velocity distribution and potential amplitude for stability of steady electron holes moving at slow speeds, coinciding with the bul…
Turbulent broadening of electron heat-flux width in electromagnetic gyrokinetic simulations of a helical scrape-off layer model
N. R. Mandell, G. W. Hammett, A. Hakim +1
We demonstrate that cross-field transport in the scrape-off layer (SOL) can be moderately increased by electromagnetic effects in high-beta regimes, resulting in a broader electron…
Quantum Lattice Representation for the Curl Equations of Maxwell Equations
George Vahala, John Hawthorne, Linda Vahala +2
A quantum lattice representation (QLA) is devised for the initial value problem of one-dimensional (1D) propagation of an electromagnetic disturbance in a scalar dielectric medium…
Proton deflectometry with in situ x-ray reference for absolute measurement of electromagnetic fields in high-energy-density plasmas
C. L. Johnson, S. Malko, W. Fox +5
We report a technique of proton deflectometry which uses a grid and an in situ reference x-ray grid image for precise measurements of magnetic fields in high-energy density plasmas…
Modeling the complete prevention of disruption-generated runaway electron beam formation with a passive 3D coil in SPARC
RA Tinguely, VA Izzo, DT Garnier +8
The potential formation of multi-mega-ampere beams of relativistic "runaway" electrons (REs) during sudden terminations of tokamak plasmas poses a significant challenge to the toka…
