Generalized Methods of Simulation of High-Voltage Glow Discharge Triode Electron Sources

MELNIK I.V.

ABSTRACT

The methods of simulation of triode technological high-voltage glow discharge electron sources are described in the paper. These methods are based on using of simple analytical relations for estimation of longitudinal dimension of anode plasma and ions concentration in it. The current-voltage characteristics for main and additional discharges have been obtained using these relations. Estimations for energetic efficiency of triode high-voltage glow discharge electron sources, as well as for the time of increasing the discharge current with changing the potential on the control electrode, are also provided. An analysis of self-coordinated electron-ion optics of triode high-voltage discharge gap have been provided with taking into account the experimental data about form and position of anode plasma boundary. The results of theoretical investigations have confirmed the advantages of using the triode technological high-voltage glow discharge electron sources in the modern electron-beam technologies.

KEYWORDS
