摘要： PROBLEM TO BE SOLVED: To provide a linear beam type microwave tube having a collector part of a cooling structure capable of avoiding direct current field concentration near a contact plug tip part, realizing a long-life life of an insulated hose and improving reliability to coolant leakage. SOLUTION: In this linear beam type microwave tube, a collector side contact plug 2 through which coolant goes in and out of a coolant passage formed around a collector and an earth side contact plug 21 connected to a coolant supply side are connected through an insulated hose 1. The connection part of the insulated hose 1 and the contact plug 2 has a structure in which a conductive pipe 3 inserted in an outer peripheral part of the insulated hose 1 is fastened tight with a hose band 6. In this conductive pipe 3, a slit 5 is formed in an end part so that the insulated hose 1 is fastened tight, a claw 4 is formed at the tip end of the end part to contacted with the collector side contact plug 2, and in the other end part, for example, a flare-like cylindrical part extended to the other end part side (earth side contact plug side) of the insulated hose 1 is formed.

摘要： PROBLEM TO BE SOLVED: To provide miniaturization, reduction of an operation cost, facilitation of operability and improvement of reliability. SOLUTION: This device is equipped with a gyrotron tube 1 in which an electron gun 2, a cavity 3, a collector 4 and an output window 5 are installed successively from one end to the other end side, a permanent magnet 20 formed cylindrically so as to enclose the gyrotron tube 1 concentrically for generating an axial direction magnetic field necessary for the operation of the gyrotron tube 1, and electromagnets 30, 50 arranged between the permanent magnet 20 and the gyrotron tube 1 for correcting the magnetic field of the permanent magnet 20. As the electromagnets 30, 50 are arranged outside the gyrotron tube 1 and the permanent magnet 20 is arranged outside the electromagnets 30, 50, the electromagnets 30, 50 assist the axial direction magnetic field necessary for the operation of the gyrotron tube 1 generated by the permanent magnet 20. Therefore, the electromagnets 30, 50 can be thinned, and the diameter of a space part on the axis formed on the permanent magnet 20 for inserting the gyrotron tube 1 and the electromagnets 30, 50 can be reduced, to thereby miniaturize the gyrotron tube 1 and the gyrotron device.

摘要： PROBLEM TO BE SOLVED: To provide a small and light collector for a radiation cooling type traveling-wave tube allowing reduction of thermal influence on members of collector components having low allowable temperatures without causing complication of its structure. SOLUTION: A connection part between a lead wire 14 for leading a voltage to collector electrodes 1, 2, 3, 4 in a vacuum envelope 12 and a feeder cable 13 for supplying the voltage to the lead wire 14 is covered with an organic potting material 8. The connection part covered with the potting material 8 is disposed within a collector cover 11 in the opposite side of the vacuum envelope 12 connected to a satellite main body, while the collector cover 11 and the vacuum envelope 12 are thermally insulated from each other by a heat insulating member 15.

摘要： PROBLEM TO BE SOLVED: To effectively radiate the heat generated in a collector in the environment at a high temperature, and while to prevent the supercooling in the environment at a low temperature. SOLUTION: A device has a heat radiating surface provided with a bimetal effect, which is formed by adhering a high-temperature thermal expansion material 6 to one surface and a low-temperature thermal expansion material 7 to the other surface of each fin 43, 44, so that one surface of the fins 43, 44 of a heat radiating fin 4 is directed to an outer space outside in the vertical direction and while a heat stay area is shrunken in the environment at a high temperature and that the heat stays in an area, which is formed so as to be directed to at least one of an outer peripheral surface of a collector 3 and a surface of a heat radiating fin 4 of the adjacent traveling wave tube 2 and which is enlarged by the peripheral wall of the collector 3 and the heat radiating fin 4, even in the case where plural traveling wave tubes 2 are mounted adjacent to each other and in parallel with each other in the horizontal direction.
