Method for winding an embedded b-zero coil

摘要

A method for winding on embedded b-zero coil maintains the integrity of superconducting main coil and the b-zero wire during coil winding and during normal operation of a superconducting MRI magnet. The b-zero coil is co-wound with an aluminum overwrap while the aluminum overwrap is being wound onto the superconducting MRI coil. The two-wire geometries are selected such that the height or thickness of the aluminum overwrap is greater than or equal to the height or thickness of the b-zero coil wire. The b-zero coil wire sits in a cavity that is created by adjacent turns.
