X-ray machine tungsten target?is referred as to the tungsten target that is used in X-ray machines. The X-ray machine is an important medical device in radiology department for breast examination.
Great advances have recently been made in the production of X-rays, chiefly by the employment of very heavy currents. The exposures necessary for producing radiographs of the thorax have been reduced from minutes to fractions of a second. To make this possible, much attention has been devoted to the target or anti-cathode, which is the critical part of the tube, for here it is that the focus of the cathode stream strikes, and the energy of the bombarding electrons is transformed into X-radiation.
Recently attention has been directed to the exceptional properties of pure metallic tungsten, and its suitability for the purpose was at once recognized. Tungsten is very tough, and does not readily disintegrate by the cathodic discharge (cathode sputtering).
