Zusammenfassung: | Results of a theoretical stability analysis of indirectly cooled conductors with a large cross section of the stabilizer are presented. The geometry of the superconducting (SC) cable was varied from a compact Rutherford type cable surrounded by aluminum stabilizer to distributed cable over the cross section. The cable geometry strongly affects the transient heat generation during the process of distribution of the transport current over the cross section of the stabilizer when a heat pulse raises the temperature above the current sharing temperature. The effect of heat transfer between adjacent turns was taken into consideration and found to be very important. Stability analysis shows that with proper design of the SC cable geometry inside the stabilizer and proper design of the coil, the stability of an indirectly cooled conductor may be enhanced by at least an order of magnitude to ensure an adequate stability margin for use in large magnets.< > |
