Transport modeling of core fueling and global particle confinement in ELM-free H-mode plasma in DIII-D

Journal of Nuclear Materials, 1995
Abstract Evaluations of core fueling rates and global particle confinement times are presented for a single-null ELM-free H-mode discharge in the DIII-D tokamak. The edge plasma transport is modeled with the B2.5 code, and the neutral transport with both the DEGAS code and the internal neutrals model in the B2.5 code.

Heating and confinement in H-mode and L-mode plasmas in DIII-D using outside launch electron cyclotron heating

Nuclear Fusion, 1990
Using the outside launch with vertical polarization, electron cyclotron heating (ECH) experiments in DIII-D were carried out at 60 GHz at fundamental and second harmonic frequencies. The results are consistent with wave absorption theory for accessibility. For fundamental heating with a cut-off layer between the launch location and the resonant surface,

Moderation of divertor heat loads by fuelling and impurity seeding in well-confined ELMy H-mode plasmas on JET

Nuclear Fusion, 2011
In anticipation of revised operational limits accompanying upgrade of the JET tokamak to an all-metal, ITER-like wall, systematic studies have been conducted of moderating divertor heat load in type I ELMy H-mode by enhanced deuterium fuelling and seeding with the extrinsic impurities neon or nitrogen.

Evolution of plasma parameters in the termination phase of high confinement H-modes at JET and implications for ITER

Nuclear Fusion, 2014
The evolution of the parameters of the plasma in the termination phase of high confinement H-modes at JET with carbon fibre composite plasma facing components (JET-C) has been analysed with a view to predict the dynamics of the plasma energy decrease for sudden terminations of the ITER QDT = 10 scenario caused by malfunction of additional heating ...

Decoupling the effects of plasma current, density and temperature on DIII-D H-mode energy confinement

Plasma Physics and Controlled Fusion, 1996
Experiments that decoupled H-mode plasma current, density and temperature have been performed on the DIII-D tokamak by the application of divertor cryopumping. Deuterium ELMing H-mode steady state discharges were operated in the single null configuration with neutral beam heating.

E–H mode transition of a high-power inductively coupled plasma torch at atmospheric pressure with a metallic confinement tube

Plasma Sources Science and Technology, 2012
Inductively coupled plasma torches need high ignition voltages for the E–H mode transition and are therefore difficult to operate. In order to reduce the ignition voltage of an RF plasma torch with a metallic confinement tube the E–H mode transition was studied. A Tesla coil was used to create a spark discharge and the E–H mode transition of the plasma

Global and pedestal confinement and pedestal structure in dimensionless collisionality scans of low-triangularity H-mode plasmas in JET-ILW

2017
A dimensionless collisionality scan in low-triangularity plasmas in the Joint European Torus with the ITER-like wall (JET-ILW) has been performed. The increase of the normalized energy confinement (defined as the ratio between thermal energy confinement and Bohm confinement time) with decreasing collisionality is observed.
