E.g. a 10kV X-Ray tube needs 10'000V to accelerate electrons to 10keV, a 100keV X-ray tube needs 100'000V, but even a millivolt will accelerate an electron, it's just that a millivolt will accelerate an … WebApr 5, 2024 · X-rays are a form of ionizing radiation—when interacting with matter, they are energetic enough to cause neutral atoms to eject electrons. Through this ionization process the energy of the X-rays is deposited in the matter.

WebJun 20, 2024 · X-ray tube operates by generating a stream of electrons by heating up a cathode (tungsten) filament. This stream of electrons is directed at high speed at a high voltage Anode disc (usually tungsten). X-radiation is produced due to the electrons’ interaction with the atomic particles of the Anode. WebThe X-ray tubes produce X-rays when an energetic beam of electrons hits a metallic target (anode). The resulting rapid deceleration of the electrons causes the emission of white …
