Superconducting magnets for transport

A levitation and horizontal guidance assembly for a high-speed ground vehicle, the design of an on-board cryostat and superconducting coil, and the setup of a linear test facility intended for the study of the levitation characteristics under laboratory conditions are described. It is pointed out that the use of combined track coils for levitation and guidance of high-speed vehicles enables the generation of additional electrodynamic forces. It requires an on-board cryostat with three working faces. The main problem is to ensure cooling. The proposed combined cooling system enables the system to operate without the spare volume of helium above the superconducting coil. A pack of sheets with pancake windings glued on and the heat exchanger as the internal protective circuit make it possible to design a compact and light-weight superconducting coil, B-112, which can be used in an actual high-speed ground vehicle
