Equivalent Capacitance of a Sheet Electron Beam
.
We consider the possibility to replace an electron beam (EB) by a "hot" equivalent capacitance that will make it possible to use "hot" equivalent circuits and long lines for analysis the EB interaction in TWTs. A sheet EB in the field of the in-phase mode of the slow wave excited by coupled impedance electrodes is considered in this paper.

A TWT model formed by a meta-magnetic plate and a metal screen is offered and analyzed. The dispersion equation of the model in the presence of a homogeneous electron beam filling the space between the plate and the screen is derived and solved. The coupling and depression coefficients are calculated by the method of differentiation ...

The TWT model based on placed in parallel impedance electrodes is used to analyze effectiveness of a sheet e-beam interaction with the in-phase mode of a slow wave excited in the impedance electrodes. The impedance approximation was used for presentation fields of E- and H-waves by zero and ±1 space harmonics, respectively. The generalized formula ...

The plane TWT model on one impedance electrode is offered and analyzed in this paper. The "hot" dispersion equation for the adjacent to the impedance electrode a homogeneous sheet electron beam is found. Formulas for coefficients of the TWT characteristic equation, coupling and depression coefficients, are derived by differentiating the dispersion equation. ...

The model based on coupled impedance electrodes was used to analyze effectiveness of a sheet e-beam interaction with the in-phase mode of a slow wave. The coupling coefficient, characterizing the interaction effectiveness, was calculated using derivatives of the equivalent parameters, the specific capacitances and inductance. The calculated coefficient was compared with that of a cylindrical ...
