8 Intensityenergy response function
The intensity-energy response function (IERF) is a measure of the efficiency of the electron-energy analyser in transmitting electrons and of the detector system in detecting them as a function of electron energy 1’ 1ff. In general, the IERF will change it the analyser pass energy, retardation ratio and aperture sizes are modified, In addition, different instruments of the same type (and from the same manufacturer) may have different IERFs for the same instrumental settings because the detectOr efficiency as a function of energy will often change during its service life. As a result. ills recommended that the Intensity scale be calibrated at regular intervals (for example, every six months) uslig calibration software available from the UK National Physical Laboratory 141 or that ERSFs be measured for selected elements (having Auger-electron or photoelectron peaks over the working range of the energy scale). Such checks should also be made if the detector surface has been exposed to any envronment that could affect Its efficiency and if insulating films (e.g from sputtering of non-conducting samples) have been deposited on analyser surfaces Local measurements of ERSFs for selected elements shall be recorded in the log book for the instrument and plotted as a function of time so that changes can be easily detected.
