Abstract

Abstract— A CPD cathode emitting button, fabricated offers excellent uniformity in the pore size and its distribution across the surface. A CPD cathode has been alloy coated and tested for emission capability. The emission density has been found > 20A/cm' thereby making it a potential candidate for high current density application.
