FIDASIM is a code that models signals produced by charge-exchange reactions between
neutrals and ions (both fast and thermal) in magnetically confined plasmas. With the ion …

Detailed measurements of the main ion (${D}^{+} $) and impurity ion (${C}^{6+} $) evolution
during the development of the H-mode pedestal across an L–H transition show significant …

Main-ion charge exchange recombination spectroscopy (MICER) uses the neutral beam
induced D α spectrum to measure the local deuterium ion (D+) temperature, rotation, and …

The transition between isotope-mixing and nonmixing states in hydrogen-deuterium mixture
plasmas is observed in the isotope (hydrogen and deuterium) mixture plasma in the Large …

Understanding the multi-scale neoclassical and turbulence physics in the edge region
(pedestal+ scrape-off layer (SOL)) is required in order to reliably predict performance in …

Experiments at the DIII-D tokamak have used dimensionless parameter scans to investigate
the dependencies of intrinsic torque and momentum transport in order to inform a prediction …

Direct measurements of deuterium main-ion toroidal rotation spanning the linear ohmic to
saturated ohmic confinement (LOC-SOC) regime and with additional electron cyclotron …

Experimental evidence is presented of near-scrape off layer (SOL) tungsten accumulation
near the crown of lower single-null L-mode discharges in the DIII-D Metal Rings Campaign …

We measure the deuterium density, the parallel drift velocity, and parallel and perpendicular
temperatures (T, T⊥) in non-Maxwellian plasmas at ASDEX Upgrade. This is done by taking …

The power balance ion heat flux in the pedestal region on DIII-D increases and becomes
increasingly anomalous (above conventional neoclassical) in experiments with higher …
