The anode material defines an X-ray tube's characteristic spectrum. This application note shows the typical spectra of several different anode materials. The spectra provided are for reference only; your spectrum may differ from these according to the particular model of detector you are using, the geometry of your measurement setup, and the voltage and current on your X-ray tube History. X-ray tubes evolved from experimental Crookes tubes with which X-rays were first discovered on November 8, 1895, by the German physicist Wilhelm Conrad Röntgen.These first generation cold cathode or Crookes X-ray tubes were used until the 1920s.The Crookes tube was improved by William Coolidge in 1913. The Coolidge tube, also called hot cathode tube, is the most widely used The rotating anode x-ray tube allows the electron beam to interact with a much larger target area, and therefore the heating of the anode is not confined to one small spot as in stationary anode tube. The rotating anode tube provides nearly 1000 times more area to interact with the electron beam than a stationary anode tube X-RAY TUBE (ANODE) 1.

Heat is considered the undesirable product of this conversion process; therefore x-radiation is created by taking the energy from the electrons and converting it into photons.This very specific energy conversion takes place in the x-ray. X-ray Tube Anode: Whereas most x-ray tubes use tungsten as the anode material, mammography equipment uses molybdenum anodes or in some designs, a dual material anode with an additional rhodium track. These materials are used because they produce a characteristic radiation spectrum that is close to optimum for breast imaging as described later

  1. Choice of X-ray Target. The wavelength, λ, of the characteristic line giving rise to a particular transition is given by Moseley's Law: 1 / λ = c (Z - σ) 2 where c and σ are constants, and Z is the atomic number of the metal used for the anode. From this equation it can seen that as the atomic number of the target increases, then the wavelength of the characteristic radiation decreases
  2. As an x-ray tube ages, the inside can become coated with tungsten, which can cause _____ in the tube. filament. Tungsten is the choice material for x-ray anodes because of it's: saturation current. increase in kVp does not result in higher mA. tube voltage

Choosing the anode material Amptek's Mini-X is available with silver (Ag), gold (Au), rhodium (Rh) or tungsten (W) as the anode material. A common question is: Why would I pick one material versus another one? In general, the excitation spectrum depends on the tube material. The plots below shows the spectra from the tubes, at 50 kV and 80 A The anode material defines an X-ray tube's characteristic spectrum. This application note shows the typical spectra of several different anode materials. The spectra provided are for reference only; your spectrum may differ from these according to the particular model of detector you are using,. In an X-ray tube, an incandescent filament heated to a very high temperature generates free electrons. These are accelerated to a high speed by an electric field before colliding with our anodes. The resulting rapid deceleration causes the electrons to release their kinetic energy in the form of heat and X-ray radiation Besides x-ray emission, some energy is released in the form of heat at the anode material, and therefore the x-ray tube must be cooled to avoid its damage. Typically water cooling systems are used for this purpose, with a water consumption of about 4L/min at a pressure of 3-5 bar and a temperature of 20-25 o C In the x-ray tube, electrons are accelerated by an electron gun across a potential difference of 20 or 30 KV. These high energy electrons strike the copper anode. Many of the high energy electrons strike electrons from the first two electron shells (historically called the K and L shells) of the copper anode

Generation of X-rays in X-ray tubes. An X-ray generator is a device used to generate X-rays .An X-ray imaging system consists of an X-ray source or generator (X-ray tube) and an image detection system. The X-ray tube (high vacuum diode) operates by emitting electrons from a heated cathode tungsten filament toward a rotating high voltage anode disc Tube current is applied across the x-ray tube from cathode to anode and affects the energy and number of electrons released. 2.

An X-ray tube consists of an anode and cathode mounted inside an evacuated glass tube. The cathode consists, of a small coil called filament , mounted in a focusing cup. The anode target is mainly made of Tungsten , separated from filament by a small gap. Electrons are boiled off the filament by applying an electric current so that it becomes white hot- the process is called 'Thermionic. X-ray machines are extremely delicate and are made using high-precision components. These must be designed as close to the client's original specifications as possible.

Most of the early x-ray tubes were what was known as bi-anode tubes, i.e., they had two anodes: the anode proper and an auxiliary anode known as the anticathode. The term anticathode was coined by Silvanus Thompson to refer to the target upon which the cathode rays (electrons) impinged These medical X-ray housings are used in a few applications and vary based on two basic tube types: rotating anode or stationary anode applications. X-ray power ranges from 200Kv down to 35kV. Rotating anode applications are typically used for CT systems or X-ray systems while stationary anode type tubes would be used in dental and bone density type applications The X-ray beams emitted from the anode travel in a variety of angular directions from the anode surface. As the angle from the anode surface is increased, the intensity of the beam increases, but the spot also becomes less focused. Thus take-off angles are typically selected in the 3 - 6 ° range.

These parts are made from a rhenium-tungsten alloy in which the quantity of rhenium added to the tungsten is controlled to achieve the necessary electrical resistance and mechanical properties. Products include targets (rotating anodes) for X-ray tubes, probe pins for semiconductors and various wires In X-ray tubes, electrons are emitted from a cathode source to a anode target through a process called thermionic emission. Electrons are then accelerated towards the anode target via a potential. X-ray gets attenuated on the way out by the target material itself causing a decrease in intensity g radually from the cathode to ano de direction as there is more of the target material to travel through. Therefore, the cathode side should be placed over the area of greatest density as this is the side with the most penetrating beam Rotating X-ray Anode When an x-ray is generated, 99% of the expended energy is lost as heat, which must be diverted away.
