INSTRUMENTATION

This state-of-the-art AXIS-Ultra^DLD spectrometer (KRATOS) is equipped with:

1. a monochromatic Al source;
2. a dual Mg/Al source;
3. an ion gun that can operate with Ar or He;
4. a He-UV-lamp for UPS, providing He(I) and He(II) lines;
5. a field-emission electron gun (FEG) for SAM; 
6. a dual, hemispherical /spherical analyzer that enables spectroscopy and mapping at improved lateral resolution, down to 3µm.

The instrument is further equipped with a glove box for sample transfer under an inert atmosphere and a mobile chamber for sample transfer under UHV conditions.

This is an older AXIS-HS spectrometer (KRATOS), equipped with

1. a monochromatic Al source;
2. a dual Mg/Al source; and,
3. a hemispherical analyzer.

Lateral resolution for mapping is 30 µm.
