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 (in special high-voltage applications or applications requiring very short switching times) hydrogen." ] ,
