摘要： PURPOSE:To reduce heat generation which is brought about on the inner circumferential side of a superconducting coil by providing a sheath for a race track- form inner vessel, which covers the inner vessel to support it and also providing a strut inside the sheath of the inner vessel. CONSTITUTION:A sheath 12 for a race track-form inner vessel, which cover the outside of the inner vessel 4, is provided. The inner vessel 4 of the inside and the sheath 12 of the inner vessel are interconnected with the peripheral side of a superconducting coil and the side surface of the superconducting coil. A strut 13 is provided in the sheath 12 of the inner vessel. With such constitution, the transmission of force between the strut 13 and the superconducting coil is performed on the peripheral side, and the heat generation due to friction which is brought about in the superconducting coil is reduced. Thereby, the quenching resistance of the superconducting coil can be increased and the reliability of a superconducting magnet device can be enhanced.

摘要： PURPOSE:To reduce the wear quantity and thermal stress of a heat receiving plate by arranging plate pieces which are made of an anisotropic material so that their surfaces which are low in heat conductivity contact each other, and setting the direction of high heat conductivity in parallel to the small-radius direction and toroidal direction of a fusion device. CONSTITUTION:Heat to a surface needs to be conducted to below the heat receiving plate 1 speedily so as to reduce the wear of the heat receiving plate 1. For the purpose, the direction 32 of heat conductivity f the anisotropic mate rial is set to the plate thickness direction 23 of the heat receiving plate 1. There are two directions 31 and 32 of high heat conductivity, so the remaining one direction 31 is a direction where the gradient of a heat load distribution is high, i.e. the toroidal direction 21. The thickness in a direction 33 of low heat conductivity is at most about 25 mm, so surfaces in this direction 33 are brought into contact and this direction is regarded as a poloidal direction 22. Consequent ly, the heat of the heat receiving surface is removed speedily from the surface, so the wear quantity of the heat receiving plate 1 is reducible and the thermal stress is also reduced.

摘要： PURPOSE:To inhibit the generation of quenching due to frictional heat by limiting the arrangement of an adhesive insulating material on a supporter, among the rows of separated superconductors or in inter-layers. CONSTITUTION:Enameled electric wires 9 and weldable electric wires 10 are connected into one electric cable, and the enameled electric wires 9 are wound in two layers in a plurality of rows on a drum-section ground insulator 2a-that is, in the vicinity of a spool drum section 1a. The upper section of the two layers in a plurality of rows is covered with a non-adhesive insulating sheet 11. The weldable electric wires 10 are wound in a plurality of layers in a plurality of rows at the upper section of the non-adhesive insulating sheet 11, positions separate from the spool drum section 1a. Sections among the rows and inter-layers of the fusion electric wires 10 are bonded by a thermally treated resin 12 for welding. The drum-section ground insulator 2a and the enameled electric wires 9 are brought into contact on contact surfaces 6, and clearances 7 among the contact surfaces 6 and the enameled electric wires 9 are formed in air gaps. Accordingly, when electromagnetic force works, a superconductor wire in a first layer near to a supporter and the supporter begin to be rubbed gently, thus inhibiting the generation of quenching.

摘要： PURPOSE:To reduce vibration of a radiation shielding plate and to decrease a quantity of heats generated in a superconducting coil and a frame of the coil by bending the plate and mounting a rib in its recess. CONSTITUTION:A radiation shielding plate 3 is bent, shaped and a rib 5 is mounted in a recess by bending. The two plate 3 are formed in a shielding box 4 with side shielding plates 6 to contain a superconducting coil 1. The plates 3 are vibrated by operations of an eddy current flowing to the plates 3 and a magnetic field of the coil 1. Since the plates 3 are bent and the rib 5 is provided in a recess of the rear surface, its rigidity is large, and a displacement due to the vibration is suppressed. Accordingly, an amount of variation in the magnetic field due to the eddy current of the plate 3 is reduced, and the quantity of heats generated from the coil 1 and a helium vessel of a coil frame can be reduced.

摘要： PURPOSE:To remove heat inputted at high-heat load and for a relatively long period of time while minimizing damages on a heat receiving surface by setting the direction of a built-up layer of pyrolytic graphite at right angles with the direction in which heat is introduced, junctioning metallurgically a cushioning material to the cooling surface side of the pyrolytic graphite, junctioning metallurgically a heat sink to the cooling surface side of the cushioning material and bringing the heat sink into contact with a cooling base plate. CONSTITUTION:Heat introduced into a heat receiving plate 6 is transferred in the direction 14 of a built-up layer of pyrolytic graphite i.e. in the direction of large thermal conductivity and passes through a cushioning material 9 to enter a heat sink 10. Heat transfer is improved by selecting the thickness of each of the heat receiving plate 6, the cushioning material 9 and the heat sink 10 in accordance with introduced heat flux and heat input hours and also by interposing a mesh 10a made of soft copper between the heat sink 10 and a cooling base plate 8 to be well associated with each other. The thickness of sublimation on the surface of a heat receiving area is minimized, and the heat of the heat receiving plate 6 is most rapidly transferred to the heat sink 10 to cool the heat of the heat sink 10 with cold water 5 via the cooling base plate 8 and a pipe 16. Thus, a long-life and highly efficient heat exchanger can be obtained.
