Abstract
With the advancement in to range of shorter wavelengths we are using the vacu-um devices for designing high power microwave components. A Traveling Wave Tube (TWT) takes the dominant position in market of powerful non-relativistic microwave am-plifiers. Multi-ray TWT (MTWT) structure of device is contributing to signification de-crease in weight and size, and performance characteristics. A characteristic of MTWT efficiency was improved by using of electron bunches capturing by electromagnetic wave field (auto-phase mode). Obtained earlier correlation based on the auto-phase theory of MTWT and motion and interaction energy balance of electron bunches in multi-ray flow with the wave field retarding system allows to estimate primary efficiency char-acteristics of the device in key of dimensional parameters (electromagnetic field and electron efficiency, gain factor). In this paper was solved the problem
of the initial evalu-ation of auto-phase MTWT characteristics which based on dimensionless parameters that are using in the theory of O-type microwave devices in step of convenient concep-tual design.
