Basic aspects of electron spectrometry with synchrotron radiation

5 Basic aspects of electron spectrometry with synchrotron radiation 

When performing electron spectrometry with monochromatized synchrotron radiation, one has to consider the dependences of the observables on the parameters relevant to the process. The essential parameters are  

The properties of monochromatized synchrotron radiation have been discussed in detail in the previous section and the characteristic features of electrostatic spectrometers will be discussed in detail in Chapter 4, with examples of photoionization processes in certain atoms and specific questions of interest presented in Chapter 5. Therefore, the following discussion is restricted to basic aspects of electron spectrometry with monochromatized synchrotron radiation, in particular to some of the fundamental properties of electron spectrometers and to the special polarization properties of this radiation which require appropriate experimental set-ups for angle-resolved electron spectrometry (without spin-analysis for the determination of spin-polarization see Section 5.4). 

The analyser accepts, transmits, analyses and possibly focuses electrons of a certain energy emitted by the sample. An important measure for the analyser s capability to meet these requirements is comprised in the luminosity L of the analyser. The luminosity is a measure of both the accepted source volume A V and 

Both T and AV are important instrumental parameters. Together with the detection efficiency s of the electron detector they determine the intensity of registered electrons, /reg( in)
