Bragg's X-Ray Tube

William Henry Bragg came to Leeds from the University of Adelaide in 1908 as Cavendish Professor of Physics. He worked on X-rays which were a relatively new discovery using apparatus like this one. This X-ray tube accelerates electrons to a high speed by applying a high voltage between two of the terminals on the tube. These high energy electrons then collide with a metal target, causing the emission of X-rays.
