1. Thyratron
   A thyratron is a type of gas filled tube used as a high energy electrical switch and controlled rectifier. Triode, tetrode and pentode variations of the thyratron have been manufactured in the past, though most are of the triode design. Because of the gas fill, thyratrons can handle much greater cu...

2. Thyratron
   A gas-tube rectifier with a grid electrode that has the ability to initiate current flow when the anode is positive. Once conduction occurs, the grid loses control until the plate current is interrupted.

5. Thyratron
   A gas-filled triode in which the voltage on the grid can trigger ionization of the gas in the tube. Once the gas is ionized, current flows from cathode to anode until the potential across the two falls below a certain level. In Linac the thyratrons are used as high-voltage relays in the chopper powe...
