This paper is devoted to theoretical and experimental analyze of self-maintained electron-ion optics of pulse high voltage glow discharge electron guns, which are an advanced instruments to using in modern production. Theoretical analyze is based on solving of equation of particles balance in anode plasma, as well as on defining of plasma boundary form and position by computer analyze of discharge photographs with using image recognizing technique. Experimental investigations have been provided for designed pilot model of electron gun.
This paper is devoted to theoretical analyze of current-voltage and energetic characteristics of triode high voltage glow discharge electron guns, which are very advanced for using in modern electron beam technologies. Regulation of high voltage discharge current is realized by lighting additional lowvoltage non-self-maintained discharge. Provided theoretical analyze is based on solving of equation of particles balance in anode plasma with taking into account the condition of discharge self-maintaining. Calculated current-voltage and energetic characteristics for different pressure and voltage of additional discharge are given. Obtained theoretical results are comprised with experimental data.
