摘要： In a bending magnet comprising a core (1) which is substantially sectoral or semi-circular in horizontally sectional configuration and in which opposed magnetic poles (3a, 3b) are formed and a vacuum chamber (4) for storage of a charged particle beam (5) is disposed in a gap between the opposed magnetic poles, and a pair of upper and lower exciting coils (2a, 2a min ; 2b, 2b min ) for generating a bending magnetic field in the gap between the magnetic poles of core, the reluctance against the magnetic flux passing through a portion (7a) of the core adjacent to the inner circumference of the orbit of the charged particle beam and a portion (7b) of the core adjacent to the outer circumference of the charged particle beam orbit is equally uniformed over the overall length of the orbit of the charged particle beam. With this construction, the magnetic flux density becomes uniform in the gap between magnetic poles where the magnetic flux passing through the inner and outer circumference side portions is concentrated and the magnetic flux distribution is uniformed in the orbital direction in the gap, thereby eliminating adverse influence upon the charged particle beam, and the bending magnet can be very effective for use in a synchrotron or a storage ring.

摘要： PROBLEM TO BE SOLVED: To provide a conductor for superconducting field winding which has a small temperature gradient and can obtain a superior cooling effect, by uniting a primary twisted superconducting conductor and an aluminum stabilizing material into one body with a copper or copper-alloy sheet, with the conductor being at the center and the stabilizing material being near the side cooling surfaces of the conductor, and filling up the inside of the conductor with solder. SOLUTION: A primary twisted superconducting conductor is formed by using superconducting strands 4 each having a threelayer structure composed of many superconducting filaments stabilized with copper and surrounded by a copper-nickel alloy and positioned to the center of a molded superconducting composite conductor. Then an aluminum stabilizing material 3 covered with a copper-nickel alloy 2 is positioned on both sides of the superconducting conductor. The superconducting conductor and material 3 covered with the alloy 2 are integrally formed by surrounding their peripheries with a copper or copper alloy sheet 1. Then the heat resistance of the composite conductor thus formed is minimized by filling up the spaces among the integrated internal components of the composite conductor with solder 5.

摘要： PROBLEM TO BE SOLVED: To obtain a highly reliable apparatus which is inexpensive, strong in mechanical strength and easy to manufacture and handle by coating a surface of a non-magnetic metal cylinder with organic insulating solvent and by applying carbon paste material to the surface. SOLUTION: An upper part and a lower part of a cylindrical matrix 1 made of non-magnetic metal with a threaded part 19 cut are coated by organic insulating solvent 2, and carbon paste 3 is applied to their surfaces to constitute a carbon film sensor 4. An upper insulation fixing base 6 and a lower insulation fixing base 7 are fixed by fixing nuts 10, 11 via spring washers 8, 9, blind nuts 20, 21 are set at their tips, and they are fixed to an insulation pipe 5 after voltage current leads 14 to 17 are attached. Thus such an apparatus can be obtained at a low cost wherein it is extremely easy to manufacture and easy to handle, a sensor part is not linear but hollow, it is free from breakage or partial peeling at the time of assembling since the sensor is applied like a thin film and baked, it is resistant against impact, easy to handle, and durable with good mechanical strength.

摘要： PURPOSE: To prevent an overcurrent from occurring when a single ground fault occurs by a method wherein a transformer whose three secondary windings are shorted is provided, a three-winding reactor is composed of coils connected in series to the three secondary windings of the transformer, and the secondary windings of the reactor are formed of superconductive conductor of the same critical current characteristics with the coils. CONSTITUTION: A transformer is composed of primary coils 4a to 4c and secondary coils 5a to 5c. The secondary coils 5a to 5c are connected to coils 6a to 6c in series respectively, and a three-winding reactor comprises the coils 6a to 6c. The secondary coils 5a and 5c and the coils 6a to 6c are formed of superconductive wire of the same critical current characteristics. In a normal state, no leakage reactance occurs in the coil 6a, but the three-winding reactor increases in zero-phase impedance when a single wire is grounded to induce a current limiting effect. When a system fault other than a single ground fault takes place, a large leakage reactance occurs in the primary coils 4a to 4c to induce a current limiting effect.

摘要： PURPOSE: To provide a superconductive coil device which enables satisfactry fixing between coil elements for effectively preventing generation of quench at a.c. energization. CONSTITUTION: The title device has a first layer tubular spool 1 of an innermost layer and a coil a tubular spool 2 constituted of two spool members 2a, 2b over lapped on an outside thereof. A cut--out part 3 is formed on an outer circumferential surface wherein a winding groove 5 is not formed in each spool member and a tape-like fixing member 4 with the same quality material as a spool member is wound along the cut--out part and two spool members are fixed by sealing by specified resin. Thereby, vibration and friction of the superconducting wire 10 involved in a.c. energization are restrained as low as possible and a highly reliable superconductive coil device of high rigidity can be provided.
