100 KILOVOLT CERAMIC-METAL THYRATRON.
Abstract
Four tubes were built of the type and design described in previous Progress Reports No. 3 and 4 which is characterized by a stack of flat gradient grids and seals protected against electrical breakdown by internal and external extensions of the ceramic envelope. They were made with two gradient grids; that is, three gaps, and were identical except for details in grid geometry and baffling. Their operating characteristics were investigated up to epy = 40 KV at a pulse repetition rate of 1000 pps in a circuit with a high charging frequency of 5000 cps. Further tests at higher voltages and a pulse repetition rate of 320 pps were performed at the U. S. Army Electronics Laboratories in Fort Monmouth, New Jersey. Three of these tubes were successfully run at epy = 70 to 78 KV with satisfactory operating characteristics. Results indicate that the design developed for this investigation is potentially capable of extending the peak forward voltage level of the hydrogen thyratron tube significantly. They also throw some light on the mechanism of commutation in multi-grid tubes. (Author)
