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. In contrast to other sources of ionizing radiation, X-rays are only produced as long as the X-ray tube is ...
The x-ray tube contains two principal elements: filament (also acts as cathode): boils off electrons by thermionic emission. target (also acts as anode): electrons strike to produce x-rays. Additional components include: expansion bellows (provide space for oil to expand) tube envelope (evacuated) tube housing. cooling dielectric oil. rotor.

Since the discovery of X-rays in 1895 by Roentgen and the heated cathode X-ray tube by Coolidge, X-ray tubes have developed into complex pieces of electromechanical engineering. They comprise around 350 parts, taking 150 assembly operations.
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.
X-rays are produced within the X-ray machine, also known as an X-ray tube. No external radioactive material is involved. Radiographers can change the current and voltage settings on the X-ray machine in order to manipulate the properties of the X-ray beam produced.
X-rays have the power to penetrate matter because of their relatively short wavelengths and high energy. The shorter the wavelength and the higher the energy of an x-ray, the deeper its ability to penetrate. A man named Wilhelm Konard Roentgen discovered the x-ray in 1895.
The video gives a detailed description of how X-Rays are produced. X-rays were first discovered by accident by a German Physicist. 00:00 Introduction 00:55 Production of X-Rays 02:57...
Simply understood, the generation of X-rays occurs when electrons are accelerated under a potential difference and turned into electromagnetic radiation. [1] An X-ray tube, with its respective components placed in a vacuum, and a generator, make up the basic components of X-ray production.
X-Ray Tube Overview. Within an x-ray tube, electrons are accelerated quickly into a large piece of heavy metal such as Tungsten. We will cover below why that works as a method to generate x-rays. Source of Electrons. The first thing that we need is a source of the electrons.
