High-Tc Superconducting Thick-Film Spiral Magnet: Development and Characterization of a Single Spiral Module.

Abstract

The objective of this project was to make characterized and numerically model prototype modules of a new type of superconducting electromagnet based on stacked spirals of superconducting thick films instead of solenoid-wound wires. Using the techniques reported in this document, a high-field magnet based on multiple stacked modules of interconnected high-Tc spiral thick films can be constructed and successfully operated. The magnetic fields produced by such an arrangement meet or exceed those predicted by a simple computer model of the magnet. Based on the measured field factor of a single 3.2-turn, 5-cm diameter module, a 2-cm long stack of 100 such modules, with a current carrying capacity of 50 A, would produce maximum field of about 7.5 kOe. This, however, is not a limiting field for this magnet design, as much larger fields can be realized with higher current or by increasing the number of spiral turns.
