description An electron-beam microcolumn alignment method and system in situ includes a split suppressor cap for a miniature Schottky electron or other field emission source. The split suppressor cap is segmented into four or more electrically separate electrode elements, which are independently driven and controlled by separate deflection voltages to scan the electron beam without requiring mechanical movement.
