Tescan GAIA3

The TESCAN GAIA3 integrates a field emission SEM with a FIB. The SEM unit is equipped with detectors for secondary and backscattered electron imaging. The ion column uses a Ga liquid ion metal source (LMIS) and a set of electrostatic lenses for bombarding the target material with a focused ion-beam for material removal or deposition. The instrument is also equipped with a Gas Injection System (GIS) for deposition of Pt, XeF2, carbon, water and also an Omniprobe for TEM thin foil extraction. The GAIA3 has a low vacuum mode, however FIB imaging and milling is only permitted in the high vacuum mode.

The GAIA3 is equipped with an Oxford X-Max 80 mm2 detector for EDX analysis and a NordlysNano Camera for EBSD analysis. Combined with a sequential cutting and recording procedure this allows for simultaneous 3D EDX and EBSD mapping of a sample.

A Leica VCT500 cryo set facilitates transfer of cryo cooled samples to the GAIA for cryo in situ TEM specimen preparation.

Kleindiek micromanipulators are also available supporting electrical and force measurements
