Abstract

PURPOSE:To prevent deterioration of an insulating oil heated by an electron gun of a gyrotron oscillating tube so as to enable long time operation by providing a cooling plate able to let a cooling medium flow to a socket. CONSTITUTION:A cooling plate 10 is mounted on a socket 5 so as to concentrically enclose an electron gun 2 and a cooling pipe 11 is circumferentially installed on the cooling plate 10 while an insulating oil as a cooling material is delivered from an oil circulating pump 9 through a cooling piping 12. Thereby, the insulating oil heated by the electron gun 2 is cooled by the cooling plate 10 in which the low temperature insulating oil is running so as to be able to prevent deterioration of the insulating oil due to local heating and the damage of a cryostat while enabling long time operation.

That is, the gyrotron oscillation tube 1 is fixed to a cryostat 3, and the cryostat 3 is fixed to an oil tank 4, respectively, to constitute an apparatus. Inside the oil tank 4, a device 6% constituting a power source for supplying power to the electron gun section 2 of the gyrotron oscillation tube 1 and a socket 5 for connecting the power source and the electron gun 2 are installed. In addition.

(Problems to be Solved by the Invention) In such a device, the socket 5 and the cryostat 3 are arranged concentrically surrounding the electron gun 2, which serves as a heat source, and the insulating oil present between them There is no convection, and the insulating oil heated by the electron gun 2 becomes lighter and gradually accumulates on the person in the figure, causing a local temperature rise in the insulating oil. Therefore, if the cryostat 3 is operated for a long period of time, there is a problem that the insulating oil deteriorates and the cryostat 3 is damaged.
