| A superconducting magnet for use in a particle accelerator of the synchotron type is disclosed. The disclosed magnet includes twin bores, each having beam pipes therein. A flux pipe is provided between the twin bores such that a 360.degree. magnetic flux path is formed. A superconducting coil encircles the bores and flux pipe, for generating the transverse magnetic field across the beam pipes. The flux pipe may be formed of non-magnetic material for a linear magnet, or alternatively may be formed of ferromagnetic laminations parallel to the direction of the magnetic field to form a superferric magnet with minimal eddy current generation. The flux pipe includes magnetic stress relief bubbles near the bores, compensating for the crowding effect near the inner radius of the flux pipe. Bands are provided around the magnet, including filler material therewithin, which are formed of a material having a high coefficient of thermal expansion; upon cooldown of the magnet, the contraction of the bands applies a inward prestress force upon the coil, counteracting the inverse Lorentz forces generated by the magnetic field. | ||||||

In another embodiment, the magnet is situated between two hollow U-shaped arms of superconducting material. The target is situated between the opposite arms of the superconducting material. Magnetic flux generated by the magnet is confined within the U-shaped arms of the superconducting material and passes through the target volume. | ||||||

| A dipole coil for use in a superconducting electromagnet employs two saddle-shaped coils in a diametrically opposed relationship. Each of the saddle-shaped coils includes central linearly extending portions, and curved saddle portions at the ends of the coil, respectively. A trapezoidal curved portion spacer is wedged into place against part of the saddle portion of the coil at the end thereof so as to exert a compressive force on such part which will inhibit displacement of the coil windings when an electromagnetic force acts thereon. In this way, friction at the coil is suppressed so as to prevent quenching. At the other end of the coil, the trapezoidal spacer includes a triangular member and a trapezoidal member spaced from one another so as to define a passageway. Leads of the coil are respectively accommodated in such passageways to prevent an excessive force from acting thereon. In this way, damage to the leads is also prevented. | ||||||
| 175 | Fabrication of detail parts for superconducting magnets by resin transfer molding | US815482 | 1991-12-31 | US5232650A | 1993-08-03 | Mark R. Behan; James G. Hartmann |
| A process for the fabrication of detail parts for superconducting magnets, such as end saddles, wedge tips, spacers and keys, by a resin transfer molding process, the attributes of which are also utilized in the subsequent fabrication of the superconducting magnet. Pursuant to the process, initially engineering specifications for the detail part are utilized to produce a master mold part for the detail part, while taking into account a calculated resin shrinkage factor. The master mold part is then utilized to fabricate a resin transfer mold for the detail part. A preform for the detail part is then placed into the resin transfer mold, and the mold is closed with the preform therein. A two-stage curing resin is then injected into the mold, and the mold is heated to partially cure the molded detail part. The partially cured detail part is then removed from the resin transfer mold. A coil winding assembly is then fabricated, while precisely positioning each partially cured detail part relative to the coil windings to produce a coil winding assembly. The coil winding assembly is then placed into a curing press, and the coil winding assembly is then pressed and heated therein. The resin softens in this final curing stage to allow each detail part to conform to the coil windings to produce a final coil winding assembly. | ||||||

| 178 | Cryogenic recondenser with remote cold box | US571870 | 1990-08-22 | USRE33878E | 1992-04-14 | Allen J. Bartlett; Bruce R. Andeen; Philip A. Lessard |
| A recondenser cycles a working volume of cryogen gas through a remote cold box and a coaxial recondensing, heat exchanger transfer line which is inserted into a cryostat. The working volume of gas is compressed to a high pressure and cooled through cooling means which include a mechanical refrigerator of the regenerator-displacer type. The cooled gas is expanded through a first JT valve to a medium pressure and further cooled. The further cooled medium pressure gas is transferred in a closed coaxial transfer line to a cryostat in which boil-off is recondensed. A second JT valve in the cryostat end of an inner tube coaxially positioned in an outer tube forming the transfer line expands the gas to a lower pressure and forms a liquid-gas mixture. The liquid-gas mixture is passed in heat exchange relation with the boil-off from an inner tube to an outer tube of a coaxial recondensing heat exchanger. The outer surface of the outer tube at the cryostat end of the transfer line has burrs which provide the necessary surface area on which to recondense the boil-off. The gas is transferred back to the cooling means through intermediate channels formed between the outer tube and the coaxially positioned inner tube. | ||||||
