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