Thermo Fisher Scienctific Helios UX 5

This FIB/SEM is equipped with micromanipulators to do TEM lamella prep. It is also equipped with EDX, STEM and a SPARC detector for elemental analysis, transmission imaging and cathodoluminescence respectively. It is also equipped with an ultra-fast beam blanker capable of reacing blanking speeds of 50 ns.
