The total energy distribution (TED) and reduced brightness from the ZrO/W(100) Schottky electron source are extended to positions 4.4 degrees off of the optical axis of the emitter. The faceted nature of the stable end form precludes a monotonic variation in emission properties with the beam angle. Both the full width at half maximum of the TED and the reduced brightness of the source increase by 37% and 18%, respectively, at an off-axis beam angle, consistent with the facet edge of the emitting (100) plane and at a constant current angular density of 0.5 mA/sr and 1800 K source temperature. Similarly, the angular magnification and work function increase by 27% and 6%, respectively, as the beam angle increases from 0 degrees to the facet edge at 4.4 degrees.
