Abstract

PURPOSE: To control oscillation phenomena, reduce ripple, and obtain stable operation by locating ring-shaped high frequency loss bodies at the base of the drift pipe and projecting at least a part of the single ring-shaped loss body on the connection hole.
CONSTITUTION: The cavity connection type low speed wave circuit 1 consists of the adjacently arranged cavities 3 and partitioned holes 4. Each partitioned wall has the hollow drift pipe 6 with the electron beam passing hole 5 at its center and the connection hole 7 for electromagnetic waves. The subsequently combined partitioned walls 4 rotate by 180 degrees, respectively, and form the cavities 3 which are divided by the respective two each of the partitioned wall 4 and the drift pipe 6. The ring-shaped alumina ceramic high frequency attenuation body 8 with a thin film high resistance layer is waxed on each partitioned wall 4 in the attenuation section so as to enclose the external wall base of the drift pipe 6.
