Abstract : The gun mounting structure was redesigned to provide improved leakage paths between grids, and between the grids and cathode. Operation of the high convergence gun proved that the aligned grids operate as a non-intercepting grid over a wide range of voltages and perveances. However, beam shape was found to be poor. Heater-current phasing was found to have a significant effect on the beam profiles obtained. The 10-kw travelingwave tube gun with aligned grids showed no change in performance after 600 hours operation. (Author)
