WebThe simplified electrical x-ray tube system defined in Figure 1 demonstrates the basic process of using a radiographic tube to generate x-ray. The potential gap of 20-150kV is generated between anode and cathode of x-ray tube by the x-ray machine [7]. A current through a filament at the cathode side is generated by a separate low voltage circuit. WebJun 23, 2015 · When an electrical current is passed through the cathode, the electrons generated by the cathode are accelerated by high voltage towards a metal target, or anode. X-rays known as Bremsstrahlung (“braking radiation”) are produced when the electrons are suddenly decelerated upon collision with the anode.
