A special electrostatic electron spectrometer designed for precise and unique experiments and an intensity calibration method for universal application in electron spectroscopy are presented. The upgrade of the analyzer enables the intensity calibration at arbitrary electron energies using elastically scattered electrons. In order to test the calibration procedure the double differential (in energy and angle) ionization cross sections (DDCS) of electrons ejected from 300 keV proton-argon collisions were measured and compared with the data of Rudd et al. . The good agreement between the two data sets verifies the applicability of the calibration method.
