Progress in toroidal magnetic confinement

Le Journal de Physique Colloques, 1979
This paper will discuss the confinement properties of plasma in magnetic fields which are characterized by their strong toroidal components. In such systems confinement is achieved by the addition of poloidal magnetic fields which are either produced internally by toroidal currents induced in the plasma - internal confinement - or by currents flowing ...

Magnetic Confinement of a Bubble of Supercooled ³He-A. [PDF]

J Low Temp Phys
Abstract We have designed and constructed a magnet surrounding a cylindrical volume of superfluid helium-3 to isolate a region of metastable, supercooled A phase, entirely surrounded by bulk A phase - isolating the ‘bubble’ from rough surfaces that can trigger the transition to the stable B phase.

Fusion, magnetic confinement [PDF]

, 1992
An overview is presented of the principles of magnetic confinement of plasmas for the purpose of achieving controlled fusion conditions. Sec. 1 discusses the different nuclear fusion reactions which can be exploited in prospective fusion reactors and explains why special technologies need to be developed for the supply of tritium or {sup 3}He, the ...

Quantized Magnetic Confinement in Quantum Wires [PDF]

Physical Review Letters, 2010
Ballistic quantum wires are exposed to longitudinal profiles of perpendicular magnetic fields composed of a spike (magnetic barrier) and a homogeneous part. An asymmetric magnetoconductance peak as a function of the homogeneous magnetic field is found, comprising quantized conductance steps in the interval where the homogeneous magnetic field and the ...

Electron cyclotron heating assisted start-up experiments in J-TEXT [PDF]

EPJ Web of Conferences, 2023
Electron cyclotron heating (ECH) breakdown and burn-through assist has been adopted to make the ITER start-up, which uses a low toroidal electric field of about 0.3 V/m, more robust.

The development of 1 MW ECRH system on J-TEXT [PDF]

EPJ Web of Conferences, 2023
A 1 MW electron cyclotron resonance heating system has been designed and developed for J-TEXT tokamak not only to enhance the total heating power but also to provide another possible way to control the plasma parameters.

Infrared detection of tungsten cracking on actively cooled ITER-like component during high power experiment in WEST

Nuclear Materials and Energy, 2023
The consequences of tungsten (W) damaging processes, such as cracking and melting, on divertor lifetime and plasma operation are high priority issues for ITER.

Very high-resolution infrared imagery of misaligned tungsten monoblock edge heating in the WEST tokamak

Nuclear Materials and Energy, 2021
Fourteen ITER-like plasma-facing units (PFUs) made of bulk tungsten were installed in the WEST tokamak divertor. Five of which were misaligned with their poloidal leading edges (LEs) exposed to the plasma heat flux: two sharp-edge PFUs and three ...
