[en] Three prototypes of superconducting (SC) magnets have been designed, constructed and tested to investigate experimentally the SC magnet characteristics and bring a new process to a commercial level. Each period of 1.5 m length contains two SC beam-bending magnets, two quadrupole lenses, ultrahigh vacuum chamber, and horizontal helium cryostat. The data obtained under experiments make it possible to design as synchrotron with sufficiently large peak-to valley field ratio and acceleration cycle up to 2-4 s. Production of ultralow pressure in a cold vacuum chamber allows to accelerate not only the protons or nuclei of heavy elements, but also the low-charged heavy ions practically without losses on the account of charge exchange on a residual gas

[en] The main design parameters of the 1.5-GeV model SPIN synchrotron withia superconducting magnetic system are presented. The synchrotron is intended for obtaining experience in constructing and operation of superconducting accelerators. The problems are discussed:of superconducting magnets manufacturing and results of measuring the magnetic field parameters of ready magnets and quadrupole lenses at room temperature and liquid helium temperature. The structure of the spin magnetic system comprises two superperi ds, each of them contains 12 regular periods and one rectitinear gap. The regular period contains two 42 cm dipole mamonets, two 15 cm quadrupole lenses and four 9 cm rectilinear gaps. A pulse electrostatic accelerator with 0.75 MV acceleratjng potential serves as a SPIN injector. Manufacturing 110 magneas consumed about 3t of transformer steel and 150 kg of superconducting material

The tirst problems to be solved are discussed: investigation of the reactions of two and more particle production in the region corresponding to the resonance production, in particular, the production of vector particles in cumulative region; investigation of spin effects in transverse momentum reactions; investigation of muon pair production at collision of relativistic nuclei and the study of muon pair hadron production. The spectrometer diagram is described

[en] The superconducting accelerator Nuclotron was put into operation at JINR, Dubna. The accelerator ring comprises 28 multipole correction magnets with an inner diameter of 132 mm. Each magnet consists of 3 or 4 types of the windings with one or two layers from Nb-Ti multifilament conductor. The windings are impregnated with epoxy resin compound and glued on the tube coil with two-phase helium. Each winding has individual 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. (author). 6 refs., 3 figs., 3 tabs
