    摘要： A superconducting coil incorporated in the superconducting magnet apparatus of the invention is shaped annular or cylindrical, and thus surrounds a photographing field. The coil has an axis which is substantially perpendicular to the line of gravity, i.e., extending in the horizontal direction. The coil is contained in a coolant vessel of a double structure filled with a coolant (e.g. liquid helium). Specifically, it is contained in a first coolant vessel, together with a predetermined small amount of liquid helium. The vessel has a receiving space defined therein and shaped similar to the coil. The space is large enough to receive the coil and the coolant with a predetermined gap. The coolant vessel comprises a first cylindrical wall contacting the inner periphery of the coil, a second cylindrical wall coaxial with the first cylindrical wall and having an inner diameter larger than the outer diameter of the coil and a pair of annular end walls arranged at both opposite ends of the first and second cylindrical walls, thereby closing, in a liquidtight/airtight manner, the gap formed by the walls. That is, the coil is received, in a manner coaxial with the first and second cylindrical walls, in a receiving space defined by the cylindrical walls and annular end walls.

    摘要： A superconducting-coil apparatus according to the present invention comprises a normal-fluid helium bath, a superfluid helium bath, a channel connecting the two baths, superconducting coils contained in the superfluid helium bath, current lead wires extending from an exciting current source to the superconducting coils, through the channel, and a valve plug normally closing the channel and adapted to open the channel when the pressure inside the superfluid helium bath rises above a predetermined level. If the superconducting coils undergo quenching while they are being excited, the superfluid helium is gasified by Joule heat, produced in the coils. As a result, the pressure inside the superfluid helium bath increases, so that the valve plug is urged to open the channel due to the pressure difference. The gasified helium directly cools those portions of the lead wires which pass through the channel, thus these wire portions are prevented from being burned out.

    摘要： A plasma processing apparatus includes a discharge window made of a dielectric material, a discharge chamber which is grounded and includes an opening formed at its one end and the discharge window provided at its other end facing the opening, a gas supply system which supplies a gas into the discharge chamber, a high-frequency power application mechanism which applies a high-frequency power to the gas to generate a plasma inside the discharge chamber, a substrate holder which can hold a substrate while facing the discharge window on the outer side of the discharge chamber, a shielding member which partially shields the plasma that impinges on the substrate, and a supporting member which supports the shielding member. The supporting member is grounded and fixed on the shielding member at a position which is farther from the substrate than the shielding member and different from that of the discharge window.
