STABLE CONTACTLESS SUSPENDER OF A SUPERCONDUCTING SOLENOID IN A CRYOSTAT
A contactless suspender of a superconducting solenoid (SCS) in a helium cryostat under the exposition to external magnetic environment is designed. Three thin-walled cylindrical inserts made of a magnetic material characterized by high induction of saturation are positioned and stiffened in a cryomagnetic system with a warm horizontal channel that is a part of the cryostat composed by the casing, helium and nitrogen containers, radiation shells and the SCS located in the helium container in order to compensate mechanical forces applied to the tube of the warm channel. One insert is located at the center of SCS and the rest of them of the same size are positioned behind the radiation shells at the edges of the SCS.
