We study, both theoretically and experimentally, the possibilities of improving the output characteristics of a nonrelativistic diffraction radiation generator (DRG) by creating a local inhomogeneity of the magnetostatic field (LIMF) in the electron-

A breadboard model of a new source of high-stable oscillations — diffraction radiation generator (DRG) with local magnetostatic non-uniformity (LMN) in the interaction space — has been developed. DRG (LMN) operates in the wide frequency range wit

Preliminary results of theoretical investigations of multi-frequency regimes in diffraction radiation oscillator are presented. Self-synchronization of two OR modes has been revealed in case of rigid self-excitation regime.

Test specimens of the 50...80 GHz diffraction radiation oscillator with a grating like a chain of coupled resonators - DRO(CCR) - are presented. The CW output power reaches 20 W at the accelerating voltage 3.6 kV, the spectral characteristics of the

The low-voltage DRO development at the short-wave end of the mm region requires recognition of the prospects for enhancement of the DRO with a thick electron beam. For this purpose, the potential of "klinotron" excitation regime, magnetostatic field

A possibility has been experimentally shown for increasing output power and extending the generation frequency bandwidth of the DRO when the diffraction grating is like a non-uniform chain of coupled millimeter-wave (70-92 GHz) half-wavelength resona

A possibility is experimentally shown for enhancing the oscillation power of the diffraction radiation oscillator (DRO) when the interaction space is designed as a consequence of coupled cavities (CCC) and the field is built up in the electron beam d

Theory of the fine structure of electron beam radiation in diffraction radiation oscillator (DRO) has been constructed. It shows that appearance of plasma waves of spatial charge in the electron beam may cause energy losses from the open resonator vo

An experimentally verified approach is suggested to execute control over the output power, frequency and signal spectrum of diffraction radiation oscillator (DRO). For this purpose, a lateral spherical echelette open resonator is added to the DRO des
