Superconducting correction impulse magnets for the accelerator Nuclotron

The superconducting accelerator Nuclotron was put into operation at JINR, Dubna. The accelerator contains 112 multipole correction windings. Each four of them are assembled as a magnet block with an inner diameter of 132 mm. The winding has one or two layers from NbTi multifilament conductor. The windings are impregnated with epoxy resin compound and glued on the tube coil with two-phase helium forced at 4.5 K. Each magnet has 100 A current leads without helium gas cooling. This very much simplifies the system of helium gas collection at the accelerator. All the magnets were tested and installed in the accelerator.
