6.2 Production of X-rays An X-ray tube is a vacuum tube designed to produce X-ray photons. The first X-ray tube was invented by Sir William Crooke s. The Crookes tube is also called a discharge tube or cold cathode tube. A schematic x-ray tube is shown below. The glass tube is evacuated to a pressure of air, of about 100 pascals, recal The necessary attributes for X-ray imaging: X ray source, object (patient) and radiation detector After an introductory description of the nature of X-rays, the most important processes in the X-ray source, the object (patient) and radiation detector for the generation of an X-ray image will be described. 2 x rays proved to be simply light waves, electromagnetic radiation, with very short wavelengths. The definition of the wavelength range considered to be in the x-ray re-gime differs somewhat among fields and applications, but is typically between 0.1 and 10 Å (0.01 to 1 nm). Longer wavelengths are considered to be in the range of extrem 29. Factors Affecting X-ray Production • The output of an x-ray tube is often described by the terms: - Quality : the penetrability of an x-ray beam - Quantity : the number of photons comprising the beam - Efficiency : the ratio of output energy as x-rays to input energy deposited by electrons 29. 30

  1. The X-ray spectrum. As a result of characteristic and bremsstrahlung radiation generation a spectrum of X-ray energy is produced within the X-ray beam. This spectrum can be manipulated by changing the X-ray tube current or voltage settings, or by adding filters to select out low energy X-rays
  2. Production of X-Rays: If a discharge tube is highly evacuated so that the pressure in the tube is of the order of 0.01 mm of mercury, certain rays are emitted by the cathode in the form of bluish streamers. These rays are called cathode rays. When cathode rays are suddenly stopped by a hard object, x-rays are produced

X-rays are a form of electromagnetic radiation with wavelengths ranging from 0.01 to 10 nanometers. In the setting of diagnostic radiology, X-rays have long enjoyed use in the imaging of body tissues and aid in the diagnosis of disease. Simply understood, the generation of X-rays occurs when electrons are accelerated under a potential difference and turned into electromagnetic radiation.[1 Noll (2006) X-ray Notes 1: Page 5 The x-ray Spectrum - For electrons with energy E, the maximum x-ray photon energy is E. - λ υ hc E =h = - Very low energy photons are absorbed by the target and by the glass in the x-ray tube. - Spectrum will have a combination of Bohr (discrete) energies and Bremsstrahlung radiation

X-ray - X-ray - Production and detection of X-rays: There are three common mechanisms for the production of X-rays: the acceleration of a charged particle, atomic transitions between discrete energy levels, and the radioactive decay of some atomic nuclei. Each mechanism leads to a characteristic spectrum of X-ray radiation. In the theory of classical electromagnetism, accelerating electric. The production of characteristic x-rays by electrons is a familiar phenomenon and gives rise to spiked peaks superimposed on the continuous x-ray spectrum. The present article is concerned primarily with the theory of K- and L-shell ionization in atoms and with experimental results for protons and alpha particles with energies up to about five.
