摘要： PURPOSE:To restrain the movement of a superconducting conductor for wirings by a method wherein a turning effort is exerted on a superconducting coil around a bobbin and the superconducting coil is impregnated with an impregnant while it is being turned. CONSTITUTION:A vacuum container 41 and a resin container 51 are evacuated by using a vacuum pump 42; the air and air bobbies of a resin 44 inside the resin container 51 are removed; air between windings for a superconducting magnet 45 is evacuated. In succession, a motor 4 is turned. In a state that an impregnation container 43b and the superconducting magnet 45 are being turned, the air between the windings is evacuated additionally. In a state that the superconducting magnet 45 has been set to a stationary rotation, a valve 52 is opened and the resin 44 is fed to the superconducting magnet 45. When the magnet has been impregnated with the resin 44, the vacuum pump 42 is stopped, a valve 54 is opened and compressed air is fed to the vacuum container 42. While the inside of the vacuum container 41 is kept at a definite pressure, the resin 44 between the windings is heated and hardened. Thereby, the windings can be impregnated with the impregnant up to every corner.

摘要： PURPOSE:To provide a non-inductie switch having an inductance small enough by twisting at least a part of a superconducting wire. CONSTITUTION:A turned part 41 is held to a winding stopper 3 as winding start of a winding body 40. At least a part of the winding body 40 of a permanent switch is twisted, which is formed by winding a superconducting wire around a core 2. Thereby, a current produced in a loop of a twisted part due to an external magnetic field 11 is reversed and offset. Accordingly, it is possible to produce a permanent current switch having inductance small enough to realize non-inductance even if there is a clearance between a winding stopping part and a current path.

摘要： PURPOSE:To suppress the highest magnetic field without increasing the number of divisions, and to obtain the title magnet on which magnetic field distribution can be formed smoothly by a method wherein a coil is divided in parallel with the main plane where the coil is located, and the position where the magnetomotive force of the coil edge part after dividing is present is shifted in the direction of an orbit. CONSTITUTION:A superconducting coil 1 is divided at least into two parts in parallel with the main planar surface where the superconducting coil 1 is present, and the position where the magnetomotive force of each divided coil 21 and 23 is present is shifted in parallel with the main plane of the above-mentioned coils in the vicinity of the part where the highest magnetic field of the generated magnetic field of the coil 1 before dividing is present. For example, two coils 1 and 1 are provided in such a manner that the orbit S100, on which charged particles 200 and 200 move, will be pinched by the coils, the charged grains 200 are deflected by the magnetic field generated by the coil 1 and they are in motion on the orbit S100. The mounting position of coil winding in the direction of the orbit S100 is shifted in such a manner that the edge parts 22 and 24 of the coil 21 on the further side of the orbit S100 and the coil 23 on the near side of the orbit S100 will not be over lapped with each other.

摘要： PURPOSE:To make the title electromagnet small in size by providing a multipolar correction coil inside the main coil. CONSTITUTION:In a superconducting deflection electromagnet equipped with a main coil 1, with which a charged particle beam will be deflected by generating a magnetic field and multipolar correction coils 31 and 32 with which highly uniform magnetic field is generated on the passing region of a charged beam, multipole correction coils 31 and 32 are provided. For example, in order to cancel the non-uniform magnetic field of the main coil 1, a 4-pole correction coil 31 composed of four banana-shaped coil and a 6-pole correction coil 32 composed of six banana-shaped coils are used. The above-mentioned tetrode correction coil 31 and 6-pole correction coil 32 are provided in the main coil 1. As a result, the 4-pole correction coil 31 and the 6-pole correction coil 32 can be provided on the main coil 1 without projecting to outside, and a cryostat 4 can be made small in size.

摘要： PURPOSE:To permit simple adjustment of the position of ports so as to simplify a design for a yoke by fixing port formation members to a yoke body formed with gaps penetrated in the peripheral direction of the yoke body from an aperture and then splitting each of the gaps to form the ports. CONSTITUTION:Each of gaps 5a penetrated in the peripheral direction of a charged particle orbit from an aperture 2 is formed in an iron yoke body 5 all over its periphery, and then iron port formation members 6 are respectively embedded in each of the gap 5a with a given space held therebetween. As a result of this, each of the gaps is split into plural sections to form ports 5b. Since the positions of the ports 5b are determined on respective corresponding positions where the members 6 are embedded, they can be easily adjusted to their respective positions of emitted light. Consequently, a design for the yoke may be simplified.

摘要： PURPOSE:To dispense with a magnetic shield pipe for an incidental beam line and ensure compact design by providing the incidental beam line directed toward a vacuum donut through a return yoke. CONSTITUTION:An incidental beam line 2 for emitting a charged particle 30 to an accumulation ring 1 is formed and a deflection electromagnet 3 is provided for deflecting the charged particle 30, both enclosed with an iron return yoke 10 of a material having relative magnetic permeability exceeding 1. In this case, a Septam magnet 9 deflects a charged particle 33 in a horizontal direction and a vacuum donut is provided for the passage of the charged particle 30. In this case, when external magnetic field is applied to the return yoke 10, almost all magnetic force lines 52 pass the iron return yoke 10 having small magnetic resistance and the charged particle 30 within the incidental beam line 2 becomes almost free from adverse effect by the magnetic field.
