Philips XL-30 FEG SEM is located in room 140 Engineering Tower (building 303 on UCI campus map)

Philips XL-30 FEG SEM with EDS (Noran 6) system is a thermionic field emission SEM which is fully automatic gun configuration controlled by advanced computer technology. The magnification is up to 800,000X with 2nm resolution. It is easy to use for examining and survey the morphology of the nano devices. This XL30 also equipped with EDS detector to provide the composition information. See SEM Philips XL30 Manual (pdf) for detailed operation procedures.
