Frequency Performance or Thyratrons

The frequency performance of small thyratrons is investigated by supplying anode voltage from a variable frequency electronic generator of 1,400 watts output capacity. At high audio frequencies there is a departure from the 60-cycle-per-second performance; the grid control characteristic resolves itself into two characteristics?? a starting characteristic and an extinguishing characteristic. The starting characteristic is shown to be a function of grid-anode capacitance and grid resistance. The extinguishing characteristic is determined by deionization effects and so is a function of frequency, grid resistance, anode current, tube geometry, and gas pressure.
