AC Losses of 19-Strand Subcables for the ANL 3.3 MJ Coil
Designs of multistrand-cable conductors for poloidal field and energy storage coils require low ac losses and cryostability. Even if the electromagnetic forces of these pulsed coils are generally supported by separate structural components the mechanical rigidity of the cable can significantly influence the performance of the coil. One way to improve the above factors is compacting or solder filling of the subcables. There have been considerable studies related to solder filling and ac losses of several kinds of subcable structures.1,2
