CONSTITUTION:A superconductive coil 1 is housed in a helium container 2, and it is fixed to the inner cylindrical part 2a of the container 2. On the circumference of said helium container, a radiation plate 4 which is cooled by the evaporated gas (about 10-40 K) of liquefied helium 3 is provided, the container 6 containing liquefied nitrogen 5 and a radiation plate 7 are arranged on the outer circumference of the radiation plate 4, and all of the them are housed in a heat-insulating vacuum container 8. A plurality of heat-insulated supporting members 9, which are supported in a radial direction, are supported in radial direction, are arranged between the inner cylinder 2a of the helium container and the inner cylinder 8a of the vacuum container. A carbon fiber reinforced plastic (CFRP) cylinder 10 is provided for heat insulation on the side of cryogenic temperature, a GFRP cylinder 11 is provided for heat insulation of a 20-77 K region, and a GFRP 12 cylinder is provided for heat-insulation of 77-300 K region.

摘要： PURPOSE:To reduce the internal stress of a coil, by inserting cotters combining materials whose thermal contraction coefficients are different with each other in a gap between a superconducting magnet and a coil vessel, providing the cotters with gradient in the width direction, and cooling the vessel. CONSTITUTION:A superconducting magnet 1 is shaped by winding and shaping superconducting wire, and accommodated in a coil vessel 2. The coil vessel 2 is constituted of an external periphery part 3, an internal periphery part 4 and side-plate parts 5 and 6. Between the superconducting coil 1 and the coil vessel 2, the followings are inserted; the cotters 7, 8 (12, 13) in the external periphery part, a spacer 9 in the internal periphery part, and spacers 10, 11 in the side-plate parts. The cotters 12, 13 (7, 8) have their own gradients and are constituted of one pair wherein a concave part and a convex part are combined in the width direction. Each of the cotters 12 and 13 is made of a material with different thermal contraction coefficient. Consequently, the gap between the superconducting coil 1 and the coil vessel 2 is automatically corrected when the superconducting magnet is cooled.

摘要： PURPOSE:To prevent increase of heat intrusion even if a plurality of measurement wires are used by varying the size of a measurement wire that connectes a measurement lement to the instrument in accordance with the range of temperature of a location where the measurement wire is positioned. CONSTITUTION:A plurality of superconducting coil 2 is placed in a vacuum heat insulating vessel 4. Measurement elements 5 of various kinds are attached to the coil 2, and the current for receiving and supplying from this element 5 is through a measurement wire 6. this measurement wire 6 is connected to the point E of an external measurement instrument through a point B that is a very low temperature area and a point C of a precooling area and further a point D that is a normal temperature area. The size of the measurement wire 6 is made relatively large between A and B and very small between B and C in order to prevent heat intrusion. With this arrangement the state of superconductivity can be stabilized and the reliability of the instrument can be improved.

摘要： PURPOSE:To prevent irregular local side-shifting motion of gasket and reduce leakage by forming circular arc section groove on the flange so as to accommodate the gasket. CONSTITUTION:Gasket 2 is inserted in the flange 5a which has a gasket groove (R-groove) of circular arc section at form. Now, the R-groove 6, is made larger than the gasket 2 so that their centers are apart from each other as much as DELTAd. Then the force acting on the gasket 2, when the flanges 5a, 5b are secured by bolts 4 is the force F2 acting to the outer radial direction of the flange 5a, 5b, therefore the gasket 2 is elongated without any irragular local side shifting.
