A an electron source utilizes a novel extraction grid conductor (20,40,41) to assist in focusing an electron beam emitted by the electron source. The extraction grid conductor (20,40,41) has a collimating conductor (29,31) that separate an extraction grid section (17,21,22) of the extraction grid conductor from conducting strips (26,24,32,33) that electrically connect the extraction grid section (17,21,22) to an external voltage source.
