摘要： PROBLEM TO BE SOLVED: To generate a good-quality double-pole magnetic field by combining electromagnets of angles of helical rotation 180 deg. or less in series, and generating a magnetic field rotating 360 deg. in the axial direction. SOLUTION: A 360 deg. helically rotating double-pole magnetic field generating electromagnet is composed of three 120 deg. helically rotating double-pole magnetic field generating electromagnets. Each 120 deg. helically rotating double-pole magnetic field generating electromagnet consists of coils 9, 10 rotating 120 deg. helically, a tube 7, block collars 8 for determining the coil positions, and collars 6 for fixing the coils. By arranging three units of these 120 deg. helically rotating double- pole magnetic field generating electromagnets in series, a double-pole magnetic field rotating 360 deg. helically is generated. The three helically rotating double-pole magnetic field generating electromagnets are fixed by a yoke 5 in a bundle. Moreover, they are assembled in a vacuum container 3, a liquid helium shield 1 and a liquid nitrogen shield 2 for keeping superconductors at low temperatures, and the vacuum container 3 is supported by a frame 4. Consequently, it becomes possible to ensure the positional precisions of the coils.

摘要： PROBLEM TO BE SOLVED: To prevent the leak of the coolant from an absorber of a charged particle accelerating ring to a vacuum chamber, and to securely maintain the super high vacuum condition inside of the vacuum chamber. SOLUTION: An absorber wall 20 as a radiation light receiver surface 10 of an absorber 1, which is arranged in the outer peripheral side surface of a vacuum chamber 2 to be irradiated with the synchrotron radiation light 6 of a particle accelerating ring, is formed with plural lines of groove so that an axis thereof is vertical to an optical axis of the synchrotron radiation light 6 and in parallel with the surface of the absorber wall 20. A wire material 30 is embedded in each groove in the condition that a part of the wire material 30 is projected from the surface of the absorber wall 20 of the radiation light receiver surface 10, and projection height of the wire material 30 from the absorber wall surface 20 and a clearance between the wire materials 30 are set so that the absorber wall surface 20 between the wire materials 30 is arranged in a shade of the wire materials 30 in relation to the synchrotron radiation light 6.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive, reasonable coil structure that suits the actual service conditions, for use in an electromagnet for an accelerator. SOLUTION: A coil wound on the magnetic pole portion of an iron core is formed of an insulated element wire 8 wound into layers which are bonded together with the adhesive of adhesion layers 41, the adhesion layers 41 having gaps 42 therein which make the adhesion between the element wires discontinuous. An epoxy resin is used as the adhesive of the adhesion layers 41 between the wires 8. Since the coil does not require the element wires to be intimately contacted with one another, it is continuously and gradually graded throughout its periphery to facilitate manufacture, thus varying its cross-sectional form throughout its periphery. The procedure of coil manufacture in conventional use is rationalized, resulting in a large reduction in cost. A method which employs a coil adhesive that sets at room temperature does not require heating equipment and a molding die which were used conventionally in coil molding, and therefore has the effect of omitting a production process such as heating.

摘要： PURPOSE: To provide a method for manufacturing a superconducting coil with less possibility for increasing the stiffness of the coil and hence increasing the stiffness of the entire superconducting equipment and for generating superconducting breakdown due to heat buildup caused by sliding between superconductive wires. CONSTITUTION: When manufacturing a superconducting coil 9 by winding a superconductive wire 4 coated with a stabilization metal 2 around a superconductor 1 after forming it into a specific shape by cold rolling 3, the superconductive wire 4 is formed into a specific shape by the cold rolling 3 and a tension is applied to the superconductive wire 4 around a mold frame 11 without annealing for adhesion to manufacture an annular coil, temperature of the superconducting coil 9 is increased to a value where the stabilization metal 2 creeps, and then the temperature is cooled to an extremely low value on operation.

摘要： PURPOSE:To provide the current lead for a superconducting equipment with which a current can be distributed uniformly on a plurality of oxide superconducting materials which are parallel-connected with each other to oxide superconducting members, and also to provide the manufacturing method with which the current lead for the superconducting equipment can be manufactured easily. CONSTITUTION:By collectively twisting a plurality of superconducting materials 9a, which are parallel-connected with each other, of an oxide superconducting member 9, each position of them is exchanged (dislocated) with each other, the voltage, which is induced by the fluctuation of a magnetic field, is made uniform, the current flowing to a part of the oxide superconducting materials 9a in concentrated form can be prevented, and a current can be uniformly distributed on each oxide superconducting material 9a. Also, when the oxide superconducting member 9 is going to be sintered, each oxide superconducting material 9a is twisted before sintering or in the initial stage of sintering, and the sintering operation is conducted to the final stage. As a result, the twisting operation is facilitated, and the current lead can be manufactured easily.

摘要： PURPOSE:To reduce a noise from an object fixing a refrigerator by a method wherein, when a superconducting magnet where a magnetic field has been installed at its circumference is attached to the refrigerator, a sound-absorbing material is installed at the inside of the shield. CONSTITUTION:Liquid He is used in order to cool a superconducting magnet 2 used for a nuclear magnetic resonance apparatus; in order to prevent radiant heat from a high temperature from entering an He tank 8 directly, double shields 6 and 7 are pasted by using an Al adhesive tape whose emissivity is small. A laminated heat-insulating material which is not shown in the figure is installed between the shield 6 and a vacuum container 11 in order to reduce a radiation from the container 11 to the shield 6. A gas 5, of high thermal conductivity, which is not solidified even at a low temperature is filled between a cold head 1a of a refrigerator 1 and a retrigerator board 4; a gas which has been cooled by the gas 5 is transmitted to the shields 6 and 7 via the board 4 and thermal anchors 9, 10; a cooling operation is executed. In addition, springs 14, 15 and a sound-absorbing material are installed between the cold head 1a and the container 11.
