摘要： PURPOSE:To attain electric adjustment for an acceleration tube with a large power loss by inserting an exciting probe into a cavity at both ends and realizing the exciting state in the cavity between the probes. CONSTITUTION:An exciting probe 18a(18b) connecting to a network analyzer 17 is inserted in a cavity 141(143) opposite to each other in a 2/3pi mode travelling superconducting acceleration tube 11 to excite the cavities 141, 143. In this case, a standing wave of the 1/3pi mode and the 2/3pi mode is excited respectively in the cavities 141, 143. When the cavity 143 is adjusted to excite a standing wave in the 2/3pi move at a prescribed frequency, then the electric adjustment is taken. Thus, the processing above is implemented to cavities 141 - 148 in the lengthwise direction of the travelling superconducting acceleration tube 11, then the electric adjustment state of the cavities 141 - 148 is attained.

摘要： PURPOSE:To improve heat radiation effect to make it possible to increase a generating electric field and a magnetic field by laminating a metal film by plasma-spraying the outside of the cavity of a thin wall-thickness superconductor in an anoxia atmosphere, and then, electroforming good thermal conductive metal on a film. CONSTITUTION:Good conductive metal is laminated in a thickness of several mums - several mms on a cavity 1 with a thin wall-thickness made up of Nb, etc., by the plasma spraying method to form a metal film 2. Next, a conductor 3 of copper with high purity with a length of several mms is formed on the film 2 by electroforming (electric thick plating). Thereby, it is possible to form a good heat conductive substrate structure, and improve heat radiation effect and increase a generating electric field and a magnetic field.

摘要： PURPOSE:To improve the accelerating voltage of a superconductive accelerating cavity by making the axial electric field strength in the cavity to be lowest in the accelerating cavity at the intake of radio wave and increased gradually toward the outlet and highest in the accelerating cavity at the outlet of radio wave. CONSTITUTION:In a travelling wave type accelerating cavity the electric field is excited successively from the intake toward the outlet of radio wave, so the electric field is increased earliest at the intake and later toward the outlet. The exciting period is longest at the intake portion, so if the electric field is made uniform all over the cavity the field strength at the intake portion is built up to a high level by the time of completion of the excitation of whole accelerating cavity, and the accelerating voltage of whole cavity is determined depending upon the field strength at the intake portion. Therefore by distributing the electric field strength in the accelerating cavity so as to increase gradually from the intake toward the outlet, the accelerating voltage can be increased substantially. In order to make the accelerating electric field higher and higher toward the end portion, it is adequate to make type group velocity of the electric field smaller and smaller toward the end portion. Thereby the accelerating voltage of the superconductive accelerating cavity can be improved or the length of the accelerating cavity can be shortened.

摘要： PURPOSE:To prevent an overlapped corrugate tape from opening by a method wherein around the center section of the edge formed corrugate tape is bent to form the diameter smaller than the outer diamter of the cable core for overlapping both edges. CONSTITUTION:A corrugate tape 2 is overlapped on a cable core 1 to feed to the former, allowing the both edges of the tape 2 to make edge forming gradually, around the center section of the transverse direction of the tube 2 being bent to develop the diameter smaller than the diameter of the core 1 in order to allow the transverse cross section to form in V shape, and forming around the outer circumference of the core 1 gradually so as to permit both overlapped edges 3 to overlap for adhering with the outer circumference of the core 1.

摘要： PURPOSE:To improve cooling efficiency by welding half-cells together via a ring-shaped piece made of a superconducting material at small-diameter portions of barrels. CONSTITUTION:Small-diameter portions of barrels of two half-cells 13 made of a dish-shaped Nb plate are put on both sides of a ring-shaped piece 14 made of Nb and welded to form the minimum-diameter portion of the barrel. Maximum-diameter portions of barrels of half-cells 13 welded with the minimum- diameter portions of barrels are welded together to obtain a preset shape. When the welding of maximum-diameter portions of barrels is repeated, a superconducting accelerating tube with the desired length is obtained. The weakest portions are reinforced by pieces 14, thus the thickness of the half-cell 13 can be made thin, and cooling efficiency can be improved.

摘要： PURPOSE:To make it possible to maintain a hollow in a superconductive condition by forming clearances of V-shape section at the outer side of the parts of plural positions of a cylinder in the axial direction wrung in the radius direction, and providing plural reinforcement supports to connect cells neighboring with the clearances in the axial direction. CONSTITUTION:Four positions in the axial direction of a niobium cylinder are contracted in the radius direction, and at the outside of the contracted parts, clearances 1 with almost V-shape section are formed in the circumferential direction, while four disks 3 forming a small hole 2 respectively are formed at the center of the inner side. Furthermore, at the center of both end surfaces of the cylinder, cylindrical small holes 4 are formed, and a superconductive hollow resonator 6 in the form to provide five cells 5 in the axial direction is formed. Then, four reinforcement supports 7 to connect the cells 5 neighboring with the circumference of the clearances 1 are arranged. By providing the reinforcement supports 7, minute deformations of the hollow resonator 6 are almost eliminated. By such a constitution, no tuning device and no feedback mechanism are required, and, since the heat invasion from the outside to destroy the superconductive condition is almost eliminated, a stable superconductive condition can be maintained.
