Cameca LEAP 5000 XR

The Local Electrode Atom Probe (LEAP 5000) allows nanoscale analysis of typical volumes of 50 nm x 50 nm x 100 nm with ppm compositional sensitivity and up to 0.2 nm spatial resolution in the analysis direction. It is equipped with a high frequency laser pulsing system, allowing the analysis of non-conductive materials and insulators and an energy compensating lens for optimal mass resolving power. Atom probe microscopy can detect all elements equally (including hydrogen) and allows 3D reconstructions of nanoscale segregation within sample volumes. The LEAP 5000XR is fitted with a FerroVac cryo/vacuum transfer suitcase which is able to dock directly with the Hydra DualBeam and the glovebox for movement of environmentally sensitive samples.

Scientific Helios Hydra DualBeam

Thermofisher Scientific Helios Hydra DualBeam with cryo-stage

The Hydra DualBeam combines a multi-source plasma column (Xe, N, O, Ar) with a high-resolution electron column with insertable backscatter and STEM detectors. The high current plasma source allows high volume milling at rates orders of magnitude greater than that of conventional gallium sources, giving significant improvements in throughput. The system is equipped with a cryo capable stage and cryo manipulator which will allow the liftout of materials that require a constant cryogenic temperature such as frozen liquid/solid interfaces. The Hydra DualBeam is fitted with a FerroVac cryo/vacuum transfer suitcase which is able to dock directly with the LEAP 5000XR and the glovebox for movement of environmentally sensitive samples.

Glovebox

The glovebox system consists of a chamber with an inert (N2) atmosphere, with a large loadlock for large samples and materials and a dock for a FerroVac cryo/vacuum transfer suitcase. This allows the mounting of materials for analysis and FIB, atom probe and TEM sample holders for subsequent transfer into their respective instruments using the FerroVac suitcase or other suitable method. These inert gas operations can be carried out at cryo temperature as well as room temperature if required. The glovebox is to be installed later in 2021.
