Microwave radiation of two passing or counter electron beams promising for amplification and generation of microwaves in regime of electronic mode as well as for energy extraction using directional radiation. In the twobeam devices on the passing beams amplification determined by the longitudinal beams interaction with different speed. Usage of counter beams allows us to consider the generation of microwaves in the longitudinal interaction with internal feedback to the flow.

This article presents a three autocollimation method (TAM) for measuring the refractive index (RI) of optical glass. The popular minimum deviation method (MDM) for RI measurement is accurate, but it is very laborious, since the procedure of determining the minimum possible angle requires many iterations. TAM allows the calculation of RI based on the measurement ...

In this paper, the slow-wave structures (SWSs) of the “chain of coupled cavities”-type (CCC) were investigated. This type of SWS is widely used for designing the microwave amplifying devices due to their excellent heat dissipation properties allowing for higher output power. The influence of the transit channel, where the electron beam propagates, on the electrodynamic ...
