The objectives of NSTX-U research are to reinforce the advantages of STs while addressing
the challenges. To extend confinement physics of low-A, high beta plasmas to lower …

This paper explores the fundamental characteristics of electron-temperature-gradient (ETG)-
driven turbulence in the tokamak pedestal. The extreme gradients in the pedestal produce …

The results of a gyrokinetic analysis of turbulent transport driven by the electron temperature
gradient (ETG) in the MAST pedestal are presented. Local nonlinear simulations from the …

The first pedestal stability and structure analysis on the new MAST Upgrade (MAST-U)
spherical tokamak H-mode plasmas is presented. Our results indicate that MAST-U …

Many mechanisms have been proposed to explain the high harmonic fast wave edge losses
in the National Spherical Torus Experiment (NSTX)(Perkins et al 2012 Phys. Rev. Lett. 109 …

This paper reports the significant advancement of our ability to model and to understand
how RF waves interact with the SOL plasma, by developing for the full torus 3D scrape-off …

A new model for electron temperature gradient (ETG) modes is developed as a component
of the multi-mode anomalous transport module [Rafiq et al., Phys Plasmas 20, 032506 …

We propose a quantum algorithm for simulating dissipative waves in inhomogeneous linear
media as a boundary-value problem. Using the so-called quantum singular value …

The equations of electrostatic drift kinetics are observed to possess a symmetry associated
with their intrinsic scale invariance. Under the assumptions of spatial periodicity, stationarity …

High power tokamaks operate with divertor heat loads capable of destroying the plasma
facing components (PFCs). High fidelity heat load predictions are necessary to ascertain the …
