Abstract

At present NIIEFA is designing superconducting correction magnets for UNK. UNK magnetic field correction system includes about 1500 various correction windings: dipole, quadrupole, sextupole and octupole. The magnet consisting of 3 concentric saddle type multipole coils with common iron yoke (“spool-piece”type) was selected as basic one. Each of the correction coils has the next optical force: sextupole-600 (T/m²)·m, quadropole-5.5 (T/m)·m, dipole-0.68 T·m. Total length is about 1.6 m, operating current ⩽20 A. The 4 full scale models of the basic correction magnet with different types of conductors and various technique of winding have been built. This report describes the main design parameters of models and the particulars of their construction. The results of manufacturing and tests (quench behavior and magnetic field measurements) are discussed
