This document is designed to allow the user to assess, on a regular basis, several key parameters of an Xâ€‘ray photoelectron spectrometer. It is not intended to provide an exhaustive performance check, but instead provides a rapid set of tests that can be conducted frequently.
Aspects of instrument behaviour covered by this document include the vacuum, measurements of spectra of conductive or non-conductive test specimens and the current state of the Xâ€‘ray source. Other important aspects of the instrument performance (e.g. lateral resolution) fall outside the scope of this document.
The document is intended for use with commercial Xâ€‘ray photoelectron spectrometers equipped with a monochromated Al KÎ± Xâ€‘ray source or with an unmonochromated Al or Mg KÎ± Xâ€‘ray source.
