Abstract
A unique cold cathode array using rugged emitter materials and a device architecture which provides shielding from ionization impact will provide the required high current density and long lifetime for high power magnetron use.    BENEFIT: Shielded cold cathodes will provide current densities scalable to over 10 A/cm2  in a scalable area.   These cathodes can be used in a number of emerging micro vacuum electron devices, including magnetrons, cross field amplifiers, traveling wave tubes and backward wave oscillators.  They can also be used in radiation and ion sources.   Ultra-rugged emitters developed in this project will also be useful in space application, especially those in corrosive environments such as low earth orbit.   )
