FIG. 1.

Schematic diagram showing the ion beam characterization system. The SAT with a supporting loop is mounted on a sapphire rod for good thermal conductivity and electric isolation. A schematic diagram of a SAT is shown on the left. Gas molecules (yellow) adsorbed on tip shank are attracted toward the apex (blue arrows) by the electric field and are ionized at the apex (red). The corresponding beam image is shown below with the scale bar equivalent to 2° from the apex.
