ABSTRACT:
An electron emitter assembly and a method for generating an electron beam are provided. The electron emitter assembly includes a laser configured to emit a first light beam and a second light beam. The electron emitter assembly further includes a mirror configured to move to a first operational position to reflect the first light beam toward a first region of a photo-cathode. The mirror is further configured to move to a second operational position to reflect the second light beam toward a second region of the photo-cathode. The photo-cathode is configured to emit a first electron beam when the first light beam contacts the first region and to emit a second electron beam when the second light beam contacts the second region. The electron emitter assembly further includes an anode configured to receive the first and second electron beams from the photo-cathode.
