The GANIL Magnet

Two series of four sector magnets are presently under construction for the SSC1 and SSC2 which are the heart of the GANIL system. Each sector, weighing about 425 tons, is a C yoke magnet with 100 mn gap and 5 square meters pole area. The last model measurements, the steel quality, the coils design and the technological aspect of the construction are mainly presented. More than 2,000 tons of steel are already cast, the machining has begun and the first sector will be delivered in February 1979.
