The object of this review is to summarize the achievements of research on the Alcator C-Mod
tokamak [Hutchinson et al., Phys. Plasmas 1, 1511 (1994) and Marmar, Fusion Sci. Technol …

The input power requirements for accessing H-mode at low density and maintaining it during
the density ramp in ITER is addressed by statistical means applied to the international H …

The transport barrier which exists at the plasma edge in the high-confinement (H-mode)
regime is now recognized as important to global energy confinement. Recently, detailed …

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 …

This paper presents investigations on the role of the edge ion heat flux for transitions from L-
mode to H-mode in Alcator C-Mod. Previous results from the ASDEX Upgrade tokamak …

Enhanced confinement modes up to a toroidal field of BT= 8 T have been studied with up to
3.5 MW of radiofrequency (rf) heating power in the ion cyclotron range of frequencies (ICRF) …

ELMy H-modes in helium-4 plasmas provide valuable information on ELMy H-mode physics
as well as a possible early low activation operational phase for next-step tokamaks, such as …

An edge temperature threshold for the LH transition is found on the Alcator C-Mod tokamak.
The critical temperature depends weakly on density and increases with and with …

The observed toroidal rotation in Alcator C-Mod Ohmic L-mode plasmas has been found to
depend strongly on the magnetic configuration. For standard discharges with a lower single …

Neutral helium He I λ 728.1 nm (2 1 P− 3 1 S) and λ 667.8 nm (2 1 P− 3 1 D) emission lines
have been observed with an array of optical fibers that cover the entire poloidal cross …
