FEI HELIOS Plasma FIB with Oxford EBSD & EDS

Plasma focused ion beam and scanning electron microscope

Home / Equipment and Facilities / Plasma Focused Ion Beam (PFIB)

The FEI HELIOS Plasma FIB with Oxford EBSD & EDS is a dual beam system which incorporates a plasma focused ion beam column (P-FIB) and a scanning electron microscope (SEM). It is especially useful for large area high-resolution analysis. Typical applications are cross-sectional analysis, serial section 3D characterization and other large area sample preparation applications.
