Collimating extraction grid conductor and method

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 cond...

Summary: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. The collimating conductor (29,31) creates an electric field that prevents emitted electrons from being attracted to the conducting strips (26,24,32,33) thereby maintaining the emitted electron beam in a substantially column-like configuration.
