Detailed Description

This system produces fine quality conductive and non-conductive 3mm diameter TEM specimens by using low energy ion beam(s) for slowly milling away materials from a sample.


This system can also use its low energy gas ion beam to remove FIB-induced damage on any FIB TEM lift-outs.
