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.
