Experimental arrangement for controlled nuclear fusion. In a Tokamak, two superimposed magnetic fields enclose the plasma: this is the toroidal field generated by external coils on the one hand and the field of a flow in the plasma on the other hand With ten times the plasma volume of the largest machine operating today, the ITER Tokamak will be a unique experimental tool, capable of longer plasmas and better confinement. The machine has been designed specifically to: 1) Produce 500 MW of fusion power The world record for fusion power is held by the European tokamak JET This account has just been created.

The UK's Tokamak Energy grew out of Culham Laboratory, home to JET - the world's most powerful tokamak - and the world's leading centre for magnetic fusion energy research

JET has been particularly suited to such studies by virtue of its combination of heating schemes and its current drive capability. In fact, JET reported the first observations of plasmas with reversed central magnetic shear and improved core confinement in the Pellet-Enhanced Performance (PEP) mode of 1988 13, 14 Technology.

Langmuir probes are still one of th Owing to the transformer, the Tokamak does not work continuously, but in pulse mode. Since, however, a power plant should not be operated in pulse mode for technical reasons, methods are examined to generate a continuous flow - for example by high-frequency waves. The fusion research plant JET is built according to the Tokamak principle

DEUTERIUM-TRITIUM PLASMA IN THE JET TOKAMAK JET Team* JET Joint Undertaking, Abingdon, Oxfordshire, United Kingdom ABSTRACT. The paper describes a series of experiments in the Joint European Torus (JET), culminating in the first tokamak discharges in deuterium-tritium fuelled mixtures. The experiments were undertaken within limit A tokamak is a machine producing a toroidal magnetic field for confining a plasma. It is one of several types of magnetic confinement devices , and it is one of the most-researched candidates for producing controlled thermonuclear fusion power These machines, notably the Joint European Torus (JET) and Tokamak Fusion Test Reactor (TFTR), had the explicit goal of reaching breakeven. Instead, they demonstrated new problems that limited their performance The Vertical Stabilization system of the JET tokamak has been recently upgraded. This new system enables a more sensitive control of the plasma geometry and can withstand larger perturbations, enabling scientists to push the plasma performance to its limits without risking a severe control loss, which might endanger the machine integrity the plasma. Most of the work has been carried out in the JET tokamak, which is the largest and best-performed tokamak in the world and located in the United Kingdom. a. u. u. q q a)t= 3.0 3.2 3.4 3.6 3.8 R (m) 7 5 3 1 7 5 3 1 01. 90/ 4.0s b)t= 5.0s LHCD ECCD NBI off-axis ICRH off-axis ICRH on-axis Ohmic NBIon-axis q q r/a 0. 0.5 1.0 a.

Real-time Systems in Tokamak Devices

JET wasn't originally designed with a divertor, so the whole system had to be constructed inside the vessel, as it would have taken too long to take the tokamak apart to install it. Luckily, there was enough mechanical engineering expertise (and space!) to add this brand new system without dismantling the whole tokamak comparable angular rotation velocities. CXRS measurem ents of C-velocities with the JET ILW are more demanding to analyse as the available C has been reduced. Measuring Neon rotation is being considered and experiments with Ne puffs for CXRS analysis are planned for the re-start phase of the next JET experimental campaign later in 2015
