Abstract :
The potential of high-temperature superconducting (HTS) magnets for use in naval mine countermeasure (MCM) systems is being investigated. Parametric studies were performed to determine an optimal system that fits within a 560-mm diameter by 3-m long envelope, and is capable of generating a dipole moment of 300 kAm/sup 2/. A demonstration model magnet, of dipole moment 15 kAm/sup 2/, was layer-wound on a 457-mm mandrel. This is one of the largest layer-wound HTS solenoid magnets constructed to date. The magnet is conduction-cooled with a two-stage cryocooler. It has low AC loss and can be ramped up to full current (381 A) in 1 second. The magnet has been tested to 400 A DC current with minimal voltage. The design and construction of the magnet will be presented.
