Cross-field particle transport in the scrape-off layer (SOL) of Alcator C-Mod [Phys. Plasmas
1, 1511 (1994)] can be characterized by an effective particle diffusivity (D eff) that increases …

Cross-field particle transport increases sharply with distance into the SOL and plays a
dominant role in themain-chamber recycling'regime in Alcator C-Mod, a regime in which …

Plasma profiles across the separatrix and scrape-off layer (SOL) in Alcator C-Mod are
examined for a range of plasma densities, currents and magnetic fields in Ohmic L-mode …

How much of the density pedestal structure is determined by fueling versus transport is still
an open question. In most current tokamaks, the scrape-off layer is not opaque enough to …

A one dimensional, absolutely calibrated pinhole camera system was installed on the DIII-D
tokamak to measure edge Lyman-alpha (Ly-α) emission from hydrogen isotopes, which can …

K-shell x-ray emission following low-energy charge exchange collisions (≤ 11 eV/amu) has
been measured for ten bare and hydrogenic ions up to U 9 1+. The data resolve capture into …

High resolution measurements on the Alcator C-Mod tokamak [IH Hutchinson et al., Phys.
Plasmas 1, 1551 (1994)] of the transport barrier in the “Enhanced D α”(EDA) regime, which …

An analytic model, derived from coupled continuity equations for the electron and neutral
deuterium densities, is consistent with many features of edge electron density profiles in the …

Recent experiments have led to a fundamental shift in our view of edge transport physics;
transport near the last-closed flux surface may be more appropriately described in terms of a …

The steady-state H-mode regime found at moderate to high density in Alcator C-Mod, known
as enhanced D α (EDA) H-mode, appears to be maintained by a continuous quasi-coherent …
