Figure 2 shows a diagram of a hot cathode (Coolidge) tube. There are different parameters characterising the X-ray beam. The beam quality is defined by the X-ray spectrum, the shape of which is defined by the voltage peak (kVp) over the tube, the anode material and the filtration of the produced X-ray …

Coolidge's work would ground X-ray tubes firmly in physics research. Industrial work took off with the production of lightbulbs, fluorescent lamps and vacuum tubes. Manufacturing plants produced radiographs, X-ray images, of steel tubes to verify their internal structures and composition. By the 1930s General Electric Company had produced one ...
