Advanced designs for highly stable superconductor systems
Experimental evidence is mounting for enhanced stability against pulsed heat loads in cable-in-conduit conductors brought about by transient pressure waves in helium. It has been suggested that this enhancement derives from improved heat transfer caused by pressure induced flow and from extra heat absorption capability due to the thermodynamic path followed by helium in the course of pressure rise and release. A basic conductor design is given to take advantage of these phenomena yet avoiding the difficulties encountered in the force-cooled conductor presently under development. The design is discussed in terms of manufacturability, performance, and applicability in large fusion magnets. A few small scale test conductors have been constructed. Preliminary test results on the performance of one of them is included. Possible variations offered by the flexibility of the basic design is also discussed.
