INVESTIGATION OF THE POSSIBILITY OF USING UNK SUPERCONDUCTING DIPOLE MAGNETS FOR PRODUCING RAPID-CYCLING MAGNETIC FIELDS

The superconducting dipoles developed as part of the UNK project have reached a magnetic field 6 T at a rate of up to 0.8 T/sec. Experimental data are presented on the conditioning, rate dependences, and dynamic losses for magnets with two types of superconducting cable (zebra and oxide). Possible ways to decrease the heat release in a dipole operating in rapid-cycling magnetic fields are examined. The results of an analysis of heat release and temperature conditions are presented for a dipole with a winding made of improved current-carrying components.
