5.1. The goal of calibration

Calibration is a determination of the error of the measurement device which was initially preset for the units corresponding to the dimensionality of the investigated physical quantity.

The goal of IS spectrometer calibration is to determine the errors in measurement of:
• energy loss (eV);
• normalised IL intensity.

The calibration of the IL intensity scale is a more difficult task than the energy scale calibration. That is why the quantitative anlysis in IS is a problem yet to be solved completely. It requires additional determination of the spectrometer's transmission function and the spectrometer's operator [Ref 2, Ref 3] and note.
