MAGNETRON AS GENERATOR OF CENTIMETER WAVES 171 



b Lo 



Fig. 2. — A schematic diagram depicting the parallelism among the conventional 

 triode oscillator, the velocity variation oscillator, the centimeter wave magnetron 

 and an equivalent lumped constant circuit. In the figure an attempt is made to align 

 corresponding parts vertically above one another. 



bunches or "spokes" which sweep past the gaps in the anode, in phase for 

 favorable interaction with the RF fields across the gaps. The bunching field
