Relay-race interaction in microwave devices

The experimental studies on synchronous excitation of decelerated harmonics of the periodic structure field by an incident nonrelativistic beam were carried out, the possibility to realize the relay-race interaction principle in microwave devices with the transverse static magnetic field was analyzed. The investigations shown that the collective interaction between the extended (wide) sheet electron bunches and the vertical component of the space harmonic field in vacuum microwave oscillators could be significant with use of relay-race interaction mechanism. Experimental and theoretical studies into the possibility of the development of O-type oscillators with short-time distributed interaction of individual electrons under the condition of coherent (relay-race) addition of radiations are being made. The possibility of realization of relay-race interaction in klynotron-type devices with an electron beam, being obliquely incident on the periodic structure, is discussed.
