IMPROVEMENTS OF THE BEHAVIOR OF THE UNK SUPERCONDUCTING MAGNETS

IHEP has manufactured and tested a preproduction batch of superconduct ing (SC) dipoles for the UNK. Using the magnets of this batch we have optimized the technology of their mass production and studied the repr oducibility of the main parameters of the magnets. Proceeding from the accumulated experience we have, introduced some changes into the desi gn and production technology of the magnets that could improve further their operating parameters. The accepted solutions were verified on s hort and full-scale models of the UNK SC magnets. This paper presents the description of the design and technological features of these magn ets and the results on their tests.
