A Cryomagnetic System with Superconducting Windings for a Magnetic Separator

A cryomagnetic system with superconducting windings is described, which creates a magnetic field of up to 2 T in the separation zone (under a cryostat) with the volume of 1200 x 200 x 100 mm(3). In order to create an extended separation zone, the magnetic system is composed as a cascade connection of three superconducting solenoids with parallel axes; the solenoids are installed in the same plane one after another in the direction of the large side of the separation zone. The helium cryostat is manufactured in the form of a parallelepiped with oval end surfaces and provides a tilt of up to 15 degrees along the longitudinal axis. The service time is 170 h for liquid helium and 100 h for liquid nitrogen.
