Team One (GA/MCA) Effort of the DOE 12 Tesla Coil Development Program. 12 Tesla ETF Toroidal Field Coil Helium Bath Cooled NbTi Alloy Concept

摘要

This report presents the conceptual design of an ETF compatible toroidal field coil, employing helium bath cooled NbTi alloy conductor. The ten TF-coil array generates a peak field of 11-1/2 tesla at 2.87 m radius, corresponding to a major axis field of 6.1 tesla. The 10 kA conductor is an uninsulated, unsoldered Rutherford cable, employing NbTiTa ally as developed in Phase I of this effort. The conductor is encased within a four element frame of stainless steel strips to provide hoop and bearing load support. (ERA citation 05:039149)
