Study for a Design of Magnet System for the SPD Detector NICA LHEP JINR

摘要

The choice of magnet system for the Spin Physics Detector of the NICA Collider of LHEP JINR is given. The inverse problem of magnetostatics is solved for a magnetic field of 0.5 tesla in the aperture a) Φ 3 m x 5 m and b) Φ 3 m x 6 m. We also discuss the design of the magnet with a field of 0.3 T. The paper presents the results obtained for the "warm" and SC versions of the magnetic system: currents (ampere-turns), the geometry (size) of the coil and the iron yoke, weight (on the whole and the individual elements), the magnet transportation and assembly.
