FEI Titan microscopes (UA)

Electron microscopy

Description

FEI X-Ant-EM

This unique instrument installed in March 2013 delivers the ultimate performance in analytical STEM available today. Its probe aberration corrector offers an amazing 0.08nm resolution in STEM.

The instrument allows a flexible choice of acceleration voltage between 60 and 300kV which is crucial for limiting the beam damage in beam sensitive materials (biological, polymers, ,..). It offers also the latest GIF Enfinium dedicated spectrometer for electron energy loss spectroscopy. This spectrometer can record 1000 spectra/s and can work in Dual-EELS mode for recording zero-loss and core-loss spectra quasi simultaneously.

In combination with STEM this offers unique opportunities for 2D atomic resolution mapping of elements and electronic properties. The Wien-filter monochromator can provide an energy resolution in EELS better than 150meV. As an alternative to EELS, the instrument also offers a highly efficient EDX system with a collection solid angle close to 1Sr.

The high efficiency of this EDX detector allows to record atomic resolution EELS and EDX data simultaneously. This feature is ideal to map the atomic positions of both heavy and light atoms which is especially interesting for those atoms with unfavorable EELS edges.

Automated software for 3D imaging in tomography is available as well. The instrument is fully remote controlled from an operator room outside the shielded room of the microscope; this dramatically improves the stability.

 

 

 

  

FEI Q-Ant-EM

This unique instrument installed in June 2010 delivers the ultimate performance in (S)TEM available today. Its double aberration correctors offer an amazing 0.05nm resolution in TEM and 0.08nm in STEM.  The instrument allows a flexible choice of acceleration voltage between 60 and 300kV which is crucial for limiting the beam damage in beam sensitive materials (biological, polymers, ,..).

It offers also the latest GIF Quantum spectrometer for electron energy loss spectroscopy. This spectrometer can record 1000 spectra/s and can work in Dual-EELS mode for recording zero-loss and core-loss spectra quasi simultaneously.
In combination with STEM this offers unique opportunities for 2D atomic resolution mapping of elements and electronic properties.

The Wien-filter monochromator can provide an energy resolution in EELS better than 150meV. As an alternative to EELS, the instrument also offers an EDX system with an energy resolution of 136eV. A rotatable biprism is available for electron holography and a Lorentz lens allows working in magnetic field free conditions.

Automated software for 3D imaging in tomography and true focus seriesis available as well. The instrument is fully remote controlled from an operator room outside the shielded room of the microscope; this dramatically improves the stability.
