Instrument status: Some Issues Some Issues, 26.5.2020 20:34, X-ray filament reaching end of the life - use max emission 10mA. Heat/cool sample holder cannot be used (does not fit properly in the stage), small leakage found in UV lamp. The lamp can be used as well as the other parts of the instrument. Service contacted to find a solution.

Detailed description:

AXIS SupraTM is an X-ray photoelectron spectrometer (XPS) with unrivalled automation and ease of use for materials surface characterisation. The patented AXIS technology ensures high electron collection efficiency in spectroscopy mode and low aberrations at high magnifications in parallel imaging mode.
X-ray photoelectron spectroscopy (XPS) provides information on elemental composition and chemical bonding states of materials, Ultraviolet photoelectron spectroscopy (UPS) provides information on valence levels and work function measurements of materials, Low energy Ion Scattering spectroscopy (ISS) provides evaluation of the elemental composition and structure of solid surfaces. XPS mode is also capable of surface mapping to provide lateral distribution maps of elemental and chemical species at the surface.
The system is also equipped by Argon cluster ion source for sample cleaning or depth profiling.
Preparation chamber connected to the analysis chamber offers sample treatment in gas reaction chamber or deposition by effusion cell and afterwards in-situ analysis.
