Design considerations of superconducting magnets as a Maglev pad

Design considerations are made on the superconducting magnet as a Maglev pad. The superconducting magnet, called L-type because of its geometry, has two superconducting coils. One is vertically oriented for thrust and guidance, while the other is horizontally oriented for suspension, in one cryostat. The two superconducting coils are both 4 m in length, extremely long in comparison with those that have been constructed so far. Winding techniques of such long coils and structure of a cryostat meeting the contradictory requirements of light weight and solidity are discussed. One of the guiding philosophies of this project was to construct a superconducting magnet with easy operation and simple maintenance, keeping a practical train in mind. In order to meet these requirements, all operating controls, liquid helium inlet valves and current leads were located on the front panel of the cryostat.
