GYROCONS AND MAGNICONS - MICROWAVE GENERATORS WITH CIRCULAR DEFLECTION OF THE ELECTRON-BEAM

A new class of microwave power amplifiers is presented in this paper. In these amplifiers, the beam is modulated by varying its spatial posi tion by means of circular deflection. Today, this class consists of tw o devices: the gyrocon and its advanced version-the magnicon. This pap er outlines the theory and the results of experimental research for bo th the gyrocon and the magnicon. The possibility of obtaining high pow er and high efficiency in both the decimeter and centimeter-wave range s shows that these devices (the magnicon especially) may turn into one of the main microwave energy sources for future particle accelerators .
