摘要：

Magnetron,　as　an　important　kind　of　high　power　microwave　devices,　has　a　wide　applications　in　many　fields,　such　as　military,　medical　and　civil　fields　[1].　As　the　key　component　of　magnetron,　cathode　plays　an　important　role　in　the　magnetron.　With　the　development　of　high　power,　high-frequency　magnetron,　the　cathode　is　needed　to　have　excellent　secondary　electron　emission　properties.　It　was　found　in　our　previous　work　that　La2O　3-Y2O3-Mo　prepared　by　solid-liquid　doping　method　exhibited　a　certain　secondary　emission　property[2].　Therefore　we　doped　Y2O3　and　Lu2O3　into　molybdenum　powder　by　a　solid-liquid　method　in　order　to　obtain　a　secondary　emission　material　with　a　higher　secondary　emission　yield　(δ).　The　emission　property　and　secondary　emission　mechanism　of　Y2O3-LU　2O3-Mo　have　been　studied　in　this　paper.　©　2010　IEEE.
