However, the heat is conducted by heat conduction through the integrally formed radiator 5 having heat dissipation fins, and flows into the slow wave circuit section 31 which is a component of the traveling wave tube 1. On the other hand, since the characteristics of the slow-wave circuit section 31 are greatly affected by temperature, if the slow-wave circuit section 31 is heated due to thermal conduction, it may cause deterioration of the electrical characteristics of the traveling wave tube 1. There is. In addition, the collector section 41, which generates a large amount of heat but has a high allowable temperature, must be cooled under the same cooling conditions as the slow wave circuit section 31, which has a small amount of heat but has a low allowable temperature, resulting in a problem that the radiator becomes larger. be.
