Abstract :
A multiple-beam X-ray tube on the basis of field emitters has been designed and developed. The X-ray tube is powered by 140 kV anode supply. Each beam is driven by 1 kV cathode to grid supply. Electron trajectories calculation and experimental measurement of I-V characteristics are presented.
