Computer sketch designing of O-type microwave device collector

Application of many-stage collectors with tape (tubular) electronic flows for making power effective microwave TWT devices is justified. It simplifies their manufacture, reduces weight and overall dimensions and raises a net efficiency. Singularities of consecutive and cycling usage of the known power software packages for a finite-element analysis and simulation modeling such as ELCUT and Anylogic are shown. It significantly reduces an initial design phase and allows an adequate estimating technical performances of each collector versions without experimental research of real prototypes. The computer analysis of electronic processes in collector space is given for three versions; the two-row construction of a four-stage collector is offered by authors. Usage of a similar construction enables an effective selection of electrons speed for account of a cross electric field between electrodes of each stage.
