Microstructural Aspects of Materials for Nondestructive Long-Pulse High-Field Magnets

The development of high-field magnets for pulsed-field applications is the subject of considerable research activity throughout the world. Induced field strengths in excess of 30 T can be produced only as pulses generated by the discharge of energy, e.g., from a capacitor bank into a resistive solenoid. A variety of electromagnetic design issues relate to the pulse duration, field strength, and volume of the coil; however, from the viewpoint of …
