Available in PDF, EPUB and Kindle. Book excerpt: Structural requirements for the magnet system include unique spatial constraints and materials restrictions to meet the operational needs of the unusual configuration. All of the magnets are liquid helium cooled which represents about 1500 tonnes of 4.5 K structure in the vacuum environment of the large vessel. Magnet support structures must satisfy complex load conditions, including electromagnetic (both normal-operating and fault conditions) and seismically induced. Improved plasma confinement, characterized by long particle lifetimes, requires attention to coil alignment and field errors. Continued monitoring of field accuracy and possible adjustment during operation are contemplated. Operating conditions for the magnet system include rapid cooldown and warm-up to minimize down time for maintenance.
