摘要：

This paper describes the superconducting magnet system of the CMD-2 detector, The magnetic field is provided by the main and two compensating superconducting solenoids, The unique features of this system are the solenoids protection method utilizing a distributed resistance along the coil and the power supply being a fluxpump type. The main solenoid produces a field up to 1.2 T in a volume of phi 0.71 m x 0.9 m, Its radiation thickness and E/M ratio are 0.38 X-0 and 5 kJ/kg, respectively. NbTi/Cu superconducting cables without any insulation and an aluminum stabilizer were used for the design of solenoid coils. The superconducting cable was wound in a stainless steel bobbin and soldered by a PbSn alloy. The cooling bath provides a temperature of 4.2 K in the system. The superconducting magnet system of the CMD-2 detector was manufactured and tested in 1989.
