| Abstract: | The possibility of developing a two-channel nanosecond relativistic microwave oscillator with a phase stability in each channel
sufficient for coherent summation of their electromagnetic fields is demonstrated experimentally. In experiments, vacuum diodes
of two independent superradiant backward wave oscillators operating in 10-GHz frequency range were connected to a common voltage
source with a subnanosecond pulse rise time, which ensured the fixation of the initial phase of electromagnetic oscillations.
The measured values of the phase difference jitter of the channel electromagnetic oscillations amount to several percent of
the oscillation period. |
