Abstract : This program involves the development of a permanent magnet focused 10 kW pulsed distributed interaction klystron which oscillates at 93.75 GHz and has been both environmentally and life tested. It is believed that this objective may be reached when the necessary improvements are made in an Exploratory Development Model tube developed under a previous contract. A permanent magnet weighing less than 25 lb should be possible. In addition, it is indicated that a higher perveance electron gun will be required to realize a higher efficiency with a shorter cavity structure tube; further efforts to improve the efficiency of the tube have been suspended. Studies indicate that the use of an electron gun with an interception grid to modulate the beam current is feasible. Construction of test diodes, tube subassemblies, and the short pulse modulator continues. (Author)
