Measurement of small island characteristics using high resolution ECE and CER at DIII-D

Journal Article Yang, J. ; Fredrickson, E. D. ; Hu, Q. ; ... - Plasma Physics and Controlled Fusion

Abstract The measurements using the high resolution electron cyclotron emission radiometry and the charge exchange and recombination spectroscopy are processed using analytic formulas to allow for the detection of islands as small as 1.9 cm. In contrast to large, saturated magnetic islands which are relatively well understood to be governed by the loss of bootstrap current inside the island, small islands are less well understood due to the difficulty of their accurate measurement in tokamaks. Here, ‘small’ islands are islands comparable in size to the ion banana width, which can be as small as 0.8 cm at DIII-D. The newmore »« less

Shattered pellet penetration in low and high energy plasmas on DIII-D

Dataset Raman, R. ; Sweeney, R. ; Moyer, R. A. ; ...

Shattered pellet injection (SPI) has been adopted as the baseline disruption mitigation system for ITER, as the radiative payload penetration into DIII-D plasmas from SPI is superior to those using the massive gas injection (MGI) method. Because of the substantial differences in the energy content of ITER plasma and those in present experiments, reliable 3D MHD modeling, benchmarked against present experiments is needed to project to ITER plasmas. In support of these needs, the depth of SPI fragment penetration in DIII-D plasmas was investigated by injecting SPI into two discharges with vastly different energy content and pedestal height. 400 Torr-Lmore »« less
AmeriFlux US-PHM Plum Island High Marsh

Dataset Giblin, Anne

This is the AmeriFlux version of the carbon flux data for the site US-PHM Plum Island High Marsh. Site Description - The site is a salt marsh located within the Plum Island Sound estuary, which is characterized by a tidal range of 2.5-3m and a vegetation cover of Spartina patens, Spartina alterniflora, Distichils spicata. Elevation of the high marsh is about 1.4m NAVD88.
