Charged particle accelerator magnet apparatus and method of use thereof
View Patent ↗The invention comprises a flattened magnet coil system that reduces space between a first magnet turning section and a second magnet turning section in a synchrotron accelerator, which reduces or eliminates need for one or more quadrupole focusing elements in the accelerator. Optionally, a coil, in the flattened magnetic coil system, is wrapped about a central metal member between yoke members of a magnet.
