Zeiss Orion NanoFab Helium and Neon Ion Microscope

HIM

The Orion NanoFab Helium Ion Microscope (HIM) operates using ionized Helium or Neon gases rather than electrons for imaging and milling of materials. Helium is typically used for imaging and milling very thin films (e.g. graphene), with a spot size ~0.5 nm.  Neon is is heavier, and thus better adapted for milling bulk materials and thin films with a spot size of ~2 nm.

(UPDATE - SIMS module currently unavailable)

As Neon ions strike the surface, about 1 in 1000 surface atoms are ejected with a charge. A custon built mass analyzer has been adapted to the CNMS HIM for Secondary Ion Mass Spectrometer (SIMS) applications, resulting in a unique tool unavailable at any other User Facility. The CNMS HIM-SIMS has an unprecedented 13 nm chemical resolution, due to a small Neon spot size. The HIM-SIMS has a mass resolution of ~500, making it suitable for elemental detection with high spatio-chemical resolution.
