The GN10 thyratron has a voltage drop across the tube of 20 volts when in conduction. The peak anode current is a massive 250 Amps. The valve is a cold cathode type and in the cathode well are the control grids.
The wide glass tube envelope is 28 mm in diameter and, excluding the IO base pins, is 91 mm tall.
Reference: Datasheet. Type GN10 was first introduced in 1958.
