- Must complete Moore 184 safety orientation
- Read and understand the SOP
- Schedule and complete in-person training session with the sample prep staff
Overview
The Phenom Pharos is a field emission gun (FEG) desktop scanning electron microscope (SEM) with an energy dispersive spectrometer (EDS), and a scanning transmission electron microscopy (STEM) detector.
- FEG source
- 2nm resolution with SED
- EDS
- <1nm resolution with STEM
- High, Medium, Low vacuum
- 1k to 20kv
The Phenom Pharos has large area mapping capabilities which can be used for correlative workflows when taken to larger SEM's and TEM's. Python scripting can be used to automate workflows. Large area image mapping.
- Navigation camera mapping of entire stub
- SEM image mapping with Phenom user interface
- SEM image mapping with Thermo Maps software
- Python scripting
