Abstract : Some 85 of the papers prepared for the first International Conference on High Magnetic Fields are published in this volume. These reports cover the most significant present work on the generation and use of very high or very special magnetic fields, including new solenoid designs for pulsed or continuous operation, developments in cryogenics, new generators and power supplies, new cooling systems for continuous-field coils, analyses and fabrication experiments on superconductive compounds and rare-earth alloys, continuing attacks on plasma-containment problems arising in controlled thermonuclear fusion research, and studies magnetic-shielding-system parameters for the protection of space travellers against high-energy radiation. The four parts of this volume cover: designs of high-field solenoids and supporting systems, high-field research programs now underway at laboratories around the world, application of high fields in solid-state and low-temperature physics, and use of high fields in plasma physics. References at the end of each paper constitute in sum the most complete bibliography of the field yet compiled.
