Western Electric 256-A Argon-filled Grid-controlled Rectifier
Thyratron

Argon gas gave the tube parameters a stability with variations in ambient temperatures unobtainable in tubes employing only mercury vapor. The tube was designed so that for any given anode potential there was a corresponding critical grid potential. If the grid was held more negative than this value, and the tube was not conducting, the anode would remain zero. If Eg were made less negative, the anode current would assume a value determined by the applied anode potential and the impedance in the anode circuit. The grid loses all control once the discharge has begun.
