Comparison between dominant NB and dominant IC heated ELMy H-mode discharges in JET [PDF]

open access: possibleNuclear Fusion, 2011
The experiment described in this paper is aimed at characterization of ELMy H-mode discharges with varying momentum input, rotation, power deposition profiles and ion to electron heating ratio obtained by varying the proportion between ion cyclotron (IC) and neutral beam (NB) heating.

Left Hemispheric Dominance of Epileptiform Discharges

Epilepsia, 1997
Summary: Purpose: We reviewed 1,360 EEG reports for all patients studied in two different neurophysiology laboratories during 1 calendar year to determine whether epileptiform discharges have a hemispheric dominance.Methods: Both inpatients and outpatients, with or without epilepsy, were included.Results: Ninety‐four records (6.9%) demonstrated ...

Attachment-dominated electron-beam-ionized discharges

Applied Physics Letters, 1976
In this letter we derive the stability criterion in discharges where two-step ionization is dominant. For stable equilibrium the attachment rate has to be greater than or equal to twice the ionization rate. Two-step ionization is often dominant in discharge-pumped visible lasers because of the relatively large number of electronically excited states ...

Runaway-electron-dominated discharges in ORMAK

Nuclear Fusion, 1980
Near the end of the ORMAK tokamak operation, a series of experiments was performed in which the bulk of the toroidal current was carried by relativistic runaway electrons. New or improved measurements of RF and microwave emission, electron temperatures, and hard-X-ray flux were made.

Predicting DNAPL mass discharge from pool-dominated source zones

Journal of Contaminant Hydrology, 2010
Models that link simplified descriptions of dense non-aqueous phase liquid (DNAPL) source zone architecture with predictions of mass flux can be effective screening tools for evaluation of source zone management strategies. Recent efforts have focused on the development and implementation of upscaled models to approximate the relationship between mass ...

Dominant Discharges at Platte-Missouri Confluence

Journal of the Waterways and Harbors Division, 1968
Principal objectives of river regulation are (1) to secure a stable alinement; (2) to develop a cross section adequate for flood flows; and (3) to maintain a better and deeper channel for navigation. Purpose (3) is often achieved by installing structures along the banks and in the river to direct the flow to form a single, deep channel which will carry

Constrictions in cathode-dominated, low-pressure argon discharges

IEEE Transactions on Plasma Science, 1996
The spatial development of constrictions across the cathode of a low-pressure, quasi-steady-state discharge in argon is recorded as a function of discharge current through the use of charge-coupled device (CCD) camera observations of light emission through a semitransparent anode.

Volumetric stability of two-step ionization dominated discharges

Journal of Applied Physics, 1989
The stability of self-sustained discharges is investigated both analytically and numerically. The dominant ionization mechanism in the discharge is assumed to be two-step ionization while both electron loss mechanisms attachment and recombination are considered.

Wall emission dominated discharge channel

The Physics of Fluids, 1981
The diffusion of ions and electron through a uniform neutral gas was treated with complete wall emission-absorption boundary conditions. Volumetric ionization and recombination processes were ignored. In the limit of the small ratio of Debye length to channel width (ε→0), the problem splits into three regions: anode sheath, cathode sheath, and quasi ...

Dominant Discharge Analysis and Calculations for Napa Creek

Building Partnerships, 2000
The dominant discharge is essentially the discharge that transports the most sediment over time. In the process of calculating the dominant discharge for Napa Creek in California, an apparent calculation deficiency was found in SAM, a hydraulic design package for flood control channels developed by the US Army Corps of Engineers.
