ABSTRACT:
A cathode arrangement for emitting electrons includes an electrode-conductive emission body that defines an emission surface from which the electrons propagate. A slit pattern is cut into the emission body for dividing the emission body into a current path. Two spaced apart conductive terminals on the emission body connect opposite ends of the current path for carrying current along the emission body that is used to heat the emission body by Joule heat.
