Periods of edge localized mode (ELM)-free H-mode with increased pedestal pressure and
width were observed in the DIII-D tokamak when density fluctuations localized to the region …

The temporal evolution of pedestal parameters is examined in the initial edge localized
mode (ELM)-free phase and inter-ELM phases of H-mode discharges in the DIII-D tokamak …

The transition from low-confinement (L-mode) to high-confinement (H-mode) plasmas has
been directly produced by injecting frozen deuterium pellets in the DIII-D tokamak. H-mode …

The L to H transition in the DIII‐D tokamak [P lasma P hysics and C ontrolled N uclear F
usion R esearch, 1986 (IAEA, Vienna, 1987), Vol. I, p. 159] is associated with two clear …

A newly installed Lithium Granule Injector (LGI) was used to pace edge localized modes
(ELM) in DIII-D. ELM pacing efficiency was studied injecting lithium granules of nominal …

The authors' data indicate that the L-mode to H-mode transition in the DIII-D tokamak is
associated with the sudden reduction in anomalous, fluctuation-connected transport across …

Neutral beam heated DIII-D expanded boundary divertor discharges have exhibited ASDEX-
like H-mode behaviour over a wide parameter range. The deuterium H-mode energy …

The spatial and temporal evolution of the total pedestal pressure profile has been measured
during the pedestal evolution between successive edge localized modes (ELMs) of type-I …

High repetition rate injection of deuterium pellets from the low-field side (LFS) of the DIII-D
tokamak is shown to trigger high-frequency edge-localized modes (ELMs) at up to 12× the …

H-mode operation is the choice for next step tokamak devices based on either conventional
or advanced tokamak physics. This choice, however, comes at a significant cost for both the …
