In 1914, two independent researchers in the United States and Germany applied for patents for a rotating anode tube. In 1915, William Coolidge patented a tube in which the electron beam was held in place by a magnetic field while the entire tube was rotated.[13] It was not until 1929, however, that Philips designed the first commercially available rotating anode tube.
