Operation of the X-ray Photoelectron Spectrometer (Thermo K-alpha XPS/UPS)

The ThermoFisher K-Alpha X-Ray Photoelectron Spectrometer (XPS) provides quantitative elemental, chemical state and functional group information from the surface of materials (top ~1-10nm). With a built-in ion beam the sample surface can be gently mill away for depth-profile analysis. This system is equipped with:

• a 180° double focusing hemispherical analyzer with 128-channel detector
• Al Kα micro-focused monochromator with variable X-ray spot size (30-400μm in 5μm steps)
• Ar⁺ beam energy range of 30-4000 eV
• 4-axis sample stage
• vacuum transfer module
