Ion gun utilizing a liquid-metal Taylor cone as the source of the
primary ions.
Note: The Taylor cone generates ion sources of very high brightness. This design enables the gun to provide beam diameters in the range \(\pu{50 nm}\) to \(\pu{1 \upmu\!m}\) for ion beam energies in the range \(\pu{5 keV}\) to \(\pu{30 keV}\), the smallest diameters generally being at the higher energies.
