PULSE MODULATOR 700-25
Huge USSR Pulse Modulator Thyratrone
The invention of the thyratron is attributed to Langmuir (1918), while the development of the hydrogen thyratron is attributed to Germeshausen (1948), although as early as 1928, Hull had described the design and operation of rare gas thyratrons. A thyratron is a type of gas-filled tube used as a high-power switch and controlled rectifier. Thyratrons can handle much higher currents than similar hard vacuum tubes. Electron multiplication occurs when the gas is ionized, creating a phenomenon called Townsend discharge. The gases used are mercury vapor, xenon, neon and hydrogen, unlike the vacuum tube (valve). A thyratron cannot be used to amplify signals linearly.
