Tungsten, the primary material under consideration as the divertor material in magnetic-
confinement nuclear fusion reactors, has been known for the last decade to form'fuzz'—a …

The global drift-ballooning (GDB) code is developed to study tokamak edge low frequency
turbulence and transport, and their relationship to global profile evolution. The code employs …

To introduce this special issue, this paper gives a brief overview of the key themes in the
Alcator C-Mod tokamak research program. These include energy, particle and momentum …

Main ion dilution has been predicted by gyrokinetic simulations to have a significant effect
on ion thermal transport in C-Mod ohmic plasmas. This effect was verified experimentally …

Recent advances in gyrokinetic simulation of core turbulence and associated transport
requires an intensified experimental effort to validate these codes using state of the art …

We derive a self-consistent equation for the turbulent transport of toroidal angular
momentum in tokamaks in the low flow ordering that only requires solving gyrokinetic Fokker …

H-mode research on Alcator C-Mod is described, with a focus on the edge transport barrier
(ETB). ETB pedestals are characterized using several diagnostics, leading to a thorough …

Several experiments on different machines and in different fast wave (FW) heating regimes,
such as hydrogen minority heating and high harmonic fast waves (HHFW), have found …

Since the installation of an ITER-like wall, the JET programme has focused on the
consolidation of ITER design choices and the preparation for ITER operation, with a specific …

Recent advances in gyrokinetic simulation have allowed for quantitative predictions of core
turbulence and associated transport. However, numerical codes must be tested against …
