A thyratron is a type of gas-filled tube used as a high-power electrical switch and controlled rectifier. Because of the gas fill, thyratrons can handle much greater currents than similar hard-vacuum tubes, since electron multiplication occurs in the ionized gas, the phenomenon called Townsend discharge. Gases used include mercury vapor, xenon, neon, and hydrogen. Unlike a vacuum tube, a thyratron cannot be used to amplify signals linearly.
In the 1920s, thyratrons were derived from early vacuum tubes such as the UV-200, which contained a small amount of argon gas to increase its sensitivity as a radio signal detector; and the German LRS Relay tube, which also contained argon gas. Gas rectifiers, which predated vacuum tubes, such as the argon-filled General Electric “Tungar bulb” and the Cooper-Hewitt mercury-pool rectifier, also provided an influence. Irving Langmuir and G. S. Meikle of GE are usually cited as the first investigators to study controlled rectification in gas tubes, about 1914. The first commercial thyratrons didn’t appear until around 1928.
