PolyAPT hosts the Invizo 6000 Atom Probe Tomograph. The Invizo 6000 is an ultra wide field of view tomograph that typically images more than 90% of the volume of the sample. This allows for a field of view of at least 200 nm on almost all materials. Samples are typically prepared using a FIB/SEM Dual Beam tool to transfer a piece of the material under investigation to the top of a tungsten wire and then sharpen it into a tip with a radius of less than 150 nm.
Specifications:
- Ultra wide field of view imaging more than 90% of the specimen volume
- FoV between 100-250 nm
- Laser pusling with a deep UV-laser with sub 10ps pulses, 257.5nm wavelength and dual beam illumination
- Mass resolution m/Δm ~ 1000
- Single Ion detection efficiency ~ 65%
- Acquisition rate of up to 50 million ions per hour
- UHV analysis chamber with a pressure of less than 10 torr
- Specimen cooling down to 25K during analysis
