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. The first-generation cold cathode or Crookes X-ray tubes were used until the 1920s. These tubes work by ionisation of residual gas within the tube.
The Straton tube, by Siemens Healthineers (formerly Siemens Medical Solutions), Erlangen, Germany, is the first X-ray tube from the class of rotating envelope tubes (RET) to be used for computed tomography.
Crookes X-ray tube from around 1910 Another Crookes x-ray tube. The device attached to the neck of the tube (right) is an "osmotic softener". When the voltage applied to a Crookes tube is high enough, around 5,000 volts or greater, [16] it can accelerate the electrons to a high enough velocity to create X-rays when they hit the anode or the glass wall of the tube.
These X-ray tubes may have been used by Professor T.H Laby's X-ray group, which was a priority research topic there. This interest was sparked by the appointment in 1889 of Professor T. R. Lyle. Lyle, who was head of the school until 1915, is thought to have been the first person in Australia to have taken an X-ray photograph iii.
Wilhelm Conrad Röntgen (/ ˈ r ɛ n t ɡ ə n,-dʒ ə n, ˈ r ʌ n t-/; [4] German: [ˈvɪlhɛlm ˈʁœntɡən] ⓘ; anglicized as Roentgen; 27 March 1845 – 10 February 1923) was a German physicist, [5] who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the inaugural Nobel Prize in ...
William Morgan (by Thomas Lawrence), on view at the Institute of Actuaries, Staple Inn Hall, London. William Morgan, FRS (26 May 1750 – 4 May 1833) [1] was a Welsh [1] physician, physicist and statistician, who is considered the father of modern actuarial science.
Wolfram Conrad Fuchs (1865–1908) was a German-born electrical engineer who became a pioneer in radiography.He opened the first x-ray laboratory in the United States in Chicago, and had completed over 1400 x-ray examinations by 1896.
The first commercially made electronic TV sets with cathode-ray tubes were manufactured by Telefunken in Germany in 1934. [32] [33] In 1947, the cathode-ray tube amusement device, the earliest known interactive electronic game as well as the first to incorporate a cathode-ray tube screen, was created. [34]
