    Every joint in a water cooled magnet is a potential cause of leakage. So the longer each individual coil is, the more the risk is reduced. With the aim of eliminating the joints within the magnet altogether, we have developed extremely long Mileon ® coils. The length of these coils, rather than being measured in meters, is now measured in hundreds, or even thousands of meters.
