Description
A new magnet design concept that intercepts Lorentz forces in high field magnets.
The number one issue facing the development of high field superconducting accelerator magnets is to overcome the high stress/strain limitations associated with the increase in Lorentz forces. The accumulated body forces in the coils degrade the conductor current density and make magnet performance unpredictable. Among the several magnet designs that attempted to deal with that issue there is room for yet another approach that promises to substantially reduce the stress on the conductor while maintaining high field quality and efficiency.
This talk is on a design approach where the magnet cross-section; called “Canted-Cosine-Theta” or CCT; intercepts the Lorentz force of each individual turn and couples it to an internal structure. The concept promises a substantial stress reduction to the conductor that goes well beyond the present target for high field magnets. We present the CCT model followed by analysis of the field, its quality, Lorentz forces and their interception by an integrated support structure.
