Paper Abstract

A variety of modifications of microwave oscillators with highfrequency stability have been developed in the Institute ofRadiophysics and electronics of Academy of Sciences of Ukraine forhigh-temperature plasma diagnostics and spectroscopy. One of them isnamed diffraction radiation oscillator (DRO). An operating principleof these oscillators is based on the diffraction radiation effect(Smith-Purcell) arising when an electron beam skims the surface ofmetallic diffraction grating placed on one open resonator's mirror.They have a low level of frequency noises near the carrirer. Forexample, this level amounts to -96 dB/Hz at 10 KHz separation from thecarrier. Oscillators are retuned in a wide frequency range (20-30%) bydisplacement of the open resonator's mirror. Main characteristics ofthe DRO at cathode current 0.1-0.12 A and cathode voltage 2-3 kV aregiven in the Table.
