Barium Depletion in Hollow Cathode Emitters [PDF]
45th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2009 Dispenser hollow cathodes rely on a consumable supply of Ba released by BaO-CaO-Al2O3 source material in the pores of a tungsten matrix to maintain a low work function surface. The examination of cathode emitters from long duration tests shows deposits of tungsten at the downstream end that appear to block the flow of Ba from the interior. In addition,
