DESIGN OF SUPERCONDUCTING MAGNET SYSTEMS. VOLUME I.
AVCO EVERETT RESEARCH LAB INC EVERETT MA
This report contains an engineering-physics design study of magnets in various configurations. The types of magnets that have been considered are solenoids, two-dimensional dipole coils such as might be used for establishing MHD fields, and quadrupole magnets such as might be used for Joffe bars. Also, systems including combinations of these magnets have been calculated. The type of coil materials that have been evaluated include room temperature copper magnets with appropriate cooling, cryogenic materials operating over a variety of cryogenic temperatures, and superconducting materials. In the case of superconductors, data is given for both stabilized and unstabilized materials. The theory of stabilization is presented in some detail. Coils are considered having several current grades and the effect of grading on reduction in coil weight and cost is given. Data is presented for dimensions, weight, cost, and refrigeration requirements, for each of these types over a range of central magnetic fields from 0 to 10 Wbm square. Optimization procedures are covered showing how the best conductor would be selected for minimum weight, or minimum cost. Large coils generate large electromagnetic forces. A considerable section is devoted to calculation of these forces, both within the coil and on external structural elements. Estimates of the weight of structure are given in terms of the coil dimensions, maximum field and stored energy. Finally, several examples of the use of the design charts and formulas are presented to familiarize the designer with the material contained in this report. Author
