An X-ray tube is a vacuum tube that converts electrical input power into X-rays. [1] The availability of this controllable source of X-rays created the field of radiography , the imaging of partly opaque objects with penetrating radiation .
Feb 20, 2016 · The X-ray tube contains a vacuum in order to accelerate the electrons with maximum efficiency. The electrons are accelerated across a potential difference ranging from 40 to 120 kV in a diagnostic X-ray tube. X-rays are produced as bremsstrahlung and characteristic radiation at the anode with an efficiency of around 1%.
X-ray tube, evacuated electron tube that produces X rays by accelerating electrons to a high velocity with a high-voltage field and causing them to collide with a target, the anode plate. The tube consists of a source of electrons, the cathode, which is usually a heated filament, and a thermally.

Mar 6, 2016 · The X-ray tube consists of two main components: the insert, which is mounted inside the tube shield. These components and the light-beam diaphragm (we will discuss its role later in this chapter) are shown in Figure 30.1 (see page 222).
The x-ray tube contains a filament that emits electrons and a target where the electrons strike to produce x-rays.
Feb 27, 2016 · The general-purpose x-ray tube is an electronic vacuum tube that consists of an anode, a cathode, and an induction motor all encased in a glass or metal enclosure (envelope). Figure 5-3 provides a labeled illustration of this design.
The X-ray tube (Figure 2) is the source of high-energy X-ray photons used to excite characteristic fluorescence radiation in the sample. The X-ray flux is generated when a beam of electrons, emitted from an incandescent filament, is accelerated through a large potential difference (normally in the range 20–100 kV) and directed at a metallic ...
