US 2026/0092994 A1 · SYSTEM AND METHOD OF AN OPTIMAL PERSISTENT SWITCH DESIGN FOR FAST RAMPING OF A SUPERCONDUCTING MAGNET

Abstract

A persistent current switch and method for fast ramping of an MRI system is provided. The persistent current switch wire is distributed in at least one layer over a bobbin. Each of the layers of the persistent current switch wire is in contact with at least one thermally conductive cooling surface. The cooling surface cools the persistent current switch wire to the threshold temperature for a superconducting state. The method includes distributing the persistent current switch wire in at least one layer over a bobbin. Each of the layers of the persistent current switch wire is in contact with at least one thermally conductive cooling surface and the cooling surface cools the persistent current switch wire to a superconducting state.
