A new type of multi-grid ceramic hydrogen thyratron tube was developed and investigated. The periodic or iterative design of the electrode structure features an indefinite number of short planar gradient grids and flat ceramic envelope rings which provide protection against electrical breakdown. Thirty tubes made with three, four, and six grids and as many gaps, demonstrated that operation at 100 kilovolt and an average power of 10 kilowatt can be attained with satisfactory characteristics for anode take-over voltage and time, and jitter. Reproducibility and life test performance were good. Commutation takes place in steps and is associated with instantaneous high voltage gap drops affecting particularly the anode gap. The data obtained through this investigation show that hydrogen thyratrons can be rated at 100 KV or possibly even higher voltages, and that greatly improved reliability can be expected from such multi-grid tubes. The development of tubes with high power ratings operating with a relatively low average anode current and long cathode life seems to be possible. Author
