High frequency thyratron evaluation
Abstract
The high frequency characteristics of a triple grid thyratron are investigated. The pentode thyratron has three closely spaced grids and operates much like a conventional tetrode thyratron. The first grid has a dual function. It functions as a priming grid, preionizing the grid cathode space, as well as a shield grid, isolating the control grid from the cathode plasma during the recovery phase. The second grid is the control grid, with negative control characteristics. The third grid is a shield grid, designed to enhance the control grid aperture deionization. This thyratron is tested in a line-type pulser to determine its high frequency limitations. It proves capable of operating at pulse repetition frequencies of up to 180 kHz.
