The simulation of electron-optical circuit of microfocus X-ray tube of transmission type with electromagnetic focusing has been carried out. Electromagnetic focusing system includes two lenses: electrostatic cathode and magnetic object lens. The author's software application FOCUS was used as a basic modeling tool. The aim of the work is to study and determine operating modes of lenses that provide a micron diameter of electron flow focal spot on tube anode in the mode of full current passage at accelerating potential of 100 kV.
Key words: : X-ray tube, cathode modulator unit, electron lens, trajectory analysis.
