X-Ray Photoelectron Spectrometer

The XPS provides chemical state information for compound identification. Its features include:

  • Dual Mg/Al anode source Auger and photoelectron separation
  • Secondary electron imaging
  • Argon Ion gun for surface cleaning and depth profiles (Scanning Auger Microscopy)
  • Quadrapole SIMS analysis by Cesium or Oxygen beam

Specification

  • Beam Energy for XPS source anode: 12kV; 14mA; spot size 1 mm
  • XPS Energy Analyzer (MAC 2): 0.3 - 4.0 eV resolution, constant; acceptance solid angle 6% of 2(pi)
  • Electron Gun
  • Argon Ion Gun
  • Auger Analyzer
  • Cesium Source
  • Duo Source (Currently Oxygen: O2+ or O-)
  • Quadrapole SIMS Analyzer
  • Data output to printer, ASCII file or Text

Specimen Considerations

  • Vacuum compatible to UHV conditions
  • Specimen size 1X1 cm
