STRUCTURAL ADVANTAGES OF DISK MAGNETS FOR SMES

A simple reorientation of the strip solenoid allows improvements in th e support of a SMES magnet is large diameter storage magnet is the foc us of the study, but smaller applications are discussed. For large dia meters, the peak field and energy storage are nearly the same for a st rip solenoid and a disk magnet, The characteristics and benefits of th e disk magnet arrangement are discussed. The disk geometry allows impr oved access for maintenance, reduces excavation, and facilitates repai r of conductors. Shimmed radial support at the outer edge allows contr olled thermal contraction, and control of conductor strains and is a r ippled solutions proposed Winding pack radial loads produce compressiv e stresses, no out of-plane loads develop and there are no bending or shear loads in the winding pack.
