Abstract
CATHODES ELECTROPHORETICALLY COATED WITH LANTHANUM HEXABORIDE (LAB6) ARE IN GENERAL POROUS, ROUGH, AND MECHANICALLY FRAGILE RODS OF LAB6 MUST BE INDIRECTLY HEATED WHICH COMPLICATES THE CATHODE DESIGN. THIS PROPOSAL IS A STUDY OF THE ELECTRON EMISSION CHARACTERISTICS OF SPUTTERED DEPOSITED LAB6 TO DETERMINE IF IT IS SUITABLE AS A THERMIONIC EMISSION SOURCE. A SPUTTERED LAB6 COATING ON RHENIUM, TANTALUM OR TUNGSTEN SHOULD ACT AS A DENSE, SMOOTH,ADHERENT ELECTRON EMITTER. BECAUSE HIGHER EMISSION CURRENTSCAN BE OBTAINED AT LOWER TEMPERATURES THAN WITH METAL CATHODES, IT IS EXPECTED TO HAVE COMMERCIAL APPLICATIONS IN AREAS SUCH AS MEDICAL IMAGING, VACUUM EQUIPMENT, ION LASERS, KLYSTRONS, TRAVELING WAVE TUBES, AND ELECTRON
