Trisection Bandpass Filter With Mixed Cross-Coupling and Different Paths for Signal Propagation

Evaluation of the thermal regime of the cathode operation of a high-voltage glow discharge electron gun, which forms a ribbon electron beam

“…Based on the test calculations that have been performed, it is shown that the accuracy of estimates using ratio (2), obtained as a solution of the system of heat balance equations (1), is quite high. For the considered models of HVGD electron guns, the calculated surface temperature of the cathode, in the case of using Rvachev arithmetic-logical relations and functions (8) to describe the geometry of the cathode assembly, is about 5-10% and is close to the estimated results obtained using the SolidWorks software complex. To carry out more accurate estimates, taking into account edge effects and the influence of the temperature of the peripheral region of the cathode on the emission of electrons from its surface, you can use either estimates through functional series using relation (4) or the pdetool toolkit of the MatLab scientific and technical calculations system.…”

Analytical Relations for Calculation the Current of Arg Discharge in the Metals’ Vapors at the Physical Conditions of Technological Process of Electron-Beam Deposition of Ceramic Coating

“…Then, taking into account the obtained relations (4, 5) for the value of the space charge ρΣ, Poisson's differential equation (1) for the boundary conditions corresponding to the electrode system of the technological device, the structural diagram of which is shown in Fig. 2, can be rewritten in a simplified form as a cubic equation, which is solved analytically using the well-known Cordano formula [19].…”
