JET isotope studies and the L H transition [PDF]

Plenary talk at international conferenceThe transition between L and H-mode has fascinated plasma physicists since its discovery [1]. It is a clear phase transition between plasma confinement regimes, which takes place when the plasma is sufficiently ...

L-H power threshold for neutral beam heated plasmas with Deuterium, Hydrogen, Helium and mixed ion species in TCV

A systematic study of the power threshold for L-H transition has been conducted in TCV. Only results from NB heated plasmas are reported. The dependencies of PLH on plasma current, plasma density and main ion species have been investigated. For Deuterium&

L-H transition in the mega-Amp spherical tokamak

, 2002
H-mode plasmas have been achieved on the MAST spherical tokamak at input power considerably higher than predicted by conventional threshold scalings.

Observation and interpretation of core ion cyclotron emission driven by D–D fusion-produced tritium ions in EAST

Nuclear Fusion
Recently, in a series of EAST discharges using deuterium neutral beam injection (NBI), tritium (T) ions were produced via deuterium–deuterium (D–D) fusion reactions, resulting in excited ion cyclotron emission (ICE) within the plasma core in H-mode ...

Reciprocating Probe Measurements of L-H Transition in LHCD H-mode on EAST

, 2013
As the power available in the initial phase of the ITER operation will be limited, accessing the high confinement mode (H-mode) with low heating power will be a critical issue.

Rapid Change of Hydrogen Neutral Energy Distribution at L/H-Transition in JFT-2M H-mode

"Rapid changes of the main ion energy distribution at transitions from L-to-H, H-to-L and during ELMs are studied with the time of flight neutral measurement on the JFT-2M tokamak.

Dynamical Model of Pressure-Gradient-Driven Turbulence and Shear Flow Generation in L-H Transition

"We present a dynamical model for the L-H transition consisting of three ordinary differential equations. This model describes temporal evolutions of three characteristic variables, i.e., the free energy contained in the pressure gradient, the turbulent

Characterisation of Pulsations close to The L-H Transition in AUG

, 2015
In fusion plasmas, a regular pulsation of the perpendicular flow velocity u? and the density fluctuations #^{~} n can occur at the transition from low to high confinement regimes (L-H transition).
