Recent reference work at NPL, in which measurements for Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) are combined, is reviewed. For the energy calibration of both AES and XPS instruments new tables have been derived. These tables extend the existing work and homogenise it with new data for the X-ray energies and calculations of the X-ray lineshapes. For the intensity...
Both predictable and unpredictable non-linearities occur in the electron counting systems which provide the intensity scales of different X-ray photoelectron spectrometers. The predictable effects are inherent in good system design and may be accurately corrected as they are both stable and repeatable. Unpredictable effects occur due to inadequate design, deterioration in service or poor setting-up...
