the spherical tokamak programme at Culham
Nuclear Fusion, 1999Co-Authors: A SykesAbstract:The spherical tokamak (ST) is the low aspect ratio limit of the conventional tokamak and appears to offer attractive physics properties in a simpler device. The START (Small Tight Aspect Ratio Tokamak) experiment provided the world's first demonstration of the properties of hot plasmas in an ST configuration and was operational at Culham from January 1991 to March 1998, obtaining plasma currents of up to 300 kA and pulse durations of ~50 ms. Its successor, MAST, is nearing completion and is a purpose built, high vacuum machine designed to have a tenfold increase in plasma volume with plasma currents of up to 2 MA. Current drive and heating will be by a combination of induction-compression as on START, a high performance central solenoid, with 1.5 MW ECRH and 5 MW of NBI. The promising results from START are reviewed, and the many challenges posed for the next generation of purpose built STs (such as MAST) are described.

refrigeration for the Culham superconducting levitron
1995Co-Authors: D N Cornish, R E Bradford, A J SteelAbstract:The Culham Superconducting Levitron has a number of unusual features which will be of interest to those working in the area of cryogenics and superconductivity. It is, as far as is known, the first machine of appreciable size in which the superconducting coils have been specifically designed to operate in gaseous helium. The use of fine-filament, twisted niobium titanium conductor, vacuum-impregnated in suitable epoxy resin results in coil performances very close to that measured on short samples of the wire.
