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 locate the position of a magnetic source with accuracy when an object to be located is movable by using the variation of the magnetic field of a magnetic field detecting means when the object is moved along a plurality of linear tracks. CONSTITUTION: An object 3 to be located containing a magnetic source is pulled at a constant speed in a magnetic shield by pulling a string 5 attached to the object 3. A counter 6 measures the pulled-out length of the string 5. Two linear tracks 4 are provided at equal distances from a magnetic field detecting section 8 on both sides of the section 8 and the object 3 is moved along the tracks 4. The magnetic field generated by the magnetic source contained in the object 3 is measured by running the object 4 four times in such a way that the object 3 is again run by turning the direction of the object 3 by 90 deg. against the moving direction after the object 3 is run in the same direction along the tracks 4. Since the variation of the magnetic field increases as the magnetic source approaches the section 8 and decreases as the magnetic source becomes farther from the section 8, the position of the magnetic source contained in the object 3 in the moving direction can be determined from the point at which the variation of the magnetic field changes from the increasing trend to the decreasing trend and the then position of the object 3.

摘要： PURPOSE:To enable precise measurement of a large cavity loss in a short time by providing a cryostat with a guide box which collects bubbles generated from a superconducting cavity provided in a cryogen in the cryostat. CONSTITUTION:A guide box 7 is so disposed as to surround a superconducting cavity 3 in liquid helium 2. The box 7 has a structure in which bubbles generated from the cavity 3 are collected without allowing them to escape. The structure prevents vapor from entering from a microwave line 5, the bottom surface 2a of a cryostat and the lateral surface 1b thereof. Besides, the upper part 7c of the guide box is shaped in a funnel so as not to allow the gas to stay. The upper part 7c of the box is connected with a transfer pipe 8 for taking out a helium gas, and the transfer pipe 8 extends from inside to outside of the cryostat 1 through a top flange 6. The temperature of the helium gas in the transfer pipe 6 rises to a room temperature while the gas flows through the transfer pipe 8 outside. The gas enters a gas flowmeter 9 and the flow rate thereof is measured. According to this constitution, a cavity loss, i.e., a Q value, can be measured precisely.

摘要： PURPOSE:To shorten the time for electrolytic polishing and to decrease the hydrogen absorption into the superconducting cavity made of niobium by disposing a cathode electrode in this cavity and electrolyzing this electrode while passing a polishing liquid into the cavity. CONSTITUTION:The triple superconducting cavity 1 made of the niobium is perpendicularly disposed. The polishing liquid 2 consisting of hydrofluoric acid and sulfuric acid stored in a storage tank 5 is ladled out by a pump 4 and is sent through a piping 3a into the superconducting cavity 1 and is further sent successively through a piping 3b and the storage tank 5, by which the polishing liquid is circulated. A cathode rod 7 inserted from an upper aperture 1b is disposed in the superconducting cavity 1. The cathode 7 is connected to a negative electrode terminal 8a of a DC power source 8 and the superconducting cavity 1 is connected to a positive electrode terminal 8b of the DC power source 8. The electrolysis is effected at >=200mA/cm current density in this state. The polished surface is easily finished to a specular surface in this way.

摘要： PURPOSE:To easily obtain high reproducibility and satisfactory superconducting characteristic by comprising an inner layer of a thin plate of Nb or Nb alloy and an outer layer of the metallic layer of superior heat conductor which forms a substrate, interposing Au thin film between the inner and outer layers, and forming a dispersion layer of Au at the inner layer. CONSTITUTION:The Au thin film is attached on a material of Nb or Nb alloy, and Au is dispersed in the material of Nb or Nb alloy after applying heat treatment. Thereby, the Au thin film can be attached solidly with high adhesiveness. Also, since Au is provided with high affinity for other metal, the metal that is a good heat conductor can be attached solidly on the Au thin film. For example, the inner layer is formed in cavity shape by applying drawing or press working to an Nb thin plate with thickness of around 0.3 to 1.0mm, and is assembled by electronic beam welding. The inner layer 1 is coated with the Au thin film 2 uniformly. The thickness of the Au thin film 2 is 0.2mum, and it is formed in potassium gold cyanide bath by electroplating. A superconducting high frequency cavity obtained in such way displays satisfactory superconducting characteristic and heat radiation characteristic.

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.
