This report describes the work performed during Phase II-b of a three-phase program for development of superpower hydrogen thyratrons for radar pulse modulator switching service. Objective ratings and other design requirements are specified. The thyratron development program included a study on cooling techniques, new cathode coatings, reservoir designs and methods of controlling hydrogen pressure, and various envelope configurations. Initial test data and life data are given. Five thyratrons were delivered, three of which were life tested for 500 hours or more. The resulting final design of the hydrogen thyratron is a ceramicmetal design having an external anode with provisions for water cooling of the anode, gradient grid, control grid, and reservoir environment.
