Edge-localized modes (ELMs) have been observed by diagnostic systems with high spatial and temporal resolution in the ASDEX and JET tokamaks. During the ELMs, substructures exist in the scrape-off layer (SOL) with sizes of 2?5?cm and lifetimes of the

A detailed comparison of core and edge confinement with different heating methods - NBI and ICRH - has been carried out in the ELMy H mode regime in JET with the Gas Box divertor. Transport in the core and characteristics of the edge pedestal have be

The neoclassical moment approach of Hirshman and Sigmar [Nucl. Fusion 21, 1079 (1981)] has been used for the first time on the Joint European Torus [J. Wesson, Tokamaks, 2nd ed. (Oxford Science Publication, Oxford, 1997), p. 581] to deduce the toroid

High βN conditions have been sustained in JET discharges with an internal transport barrier (ITB) by controlling edge conditions and pressure peaking. The behaviour of ideal and resistive MHD instabilities at high βN has been studied as a function

Experiments in JET have concentrated on steady state discharges with internal transport barriers (ITBs). The ITBs are formed during the current rise phase of the discharge with low magnetic shear ( = r/q(dq/dr)) in the centre and with high additional

The plasma turbulence in the boundary of fusion relevant experiments is known to have a quasi two-dimensional nature: the scale lengths perpendicular to the magnetic field are in the order of mm to cm, but parallel to the magnetic field, the correlat

As the reference operating regime for ITER, ELMy H mode investigations have received high priority in the JET experimental programme. Recent experiments have concentrated in particular on operation simultaneously at high density and high confinement

Results achieved on JET during the 1997-1999 experimental campaigns in the physics of energetic ions and runaway electrons are reviewed. Heating of deuterium-tritium (DT) plasmas by fusion born alpha particles is found to be similar to that achieved
