摘要：

Systematic studies were performed to investigate the distorting effect of the electron energy dependence of the channeltron detector efficiency on the shape of data distributions in electron spectroscopy. In agreement with earlier results for electron energies up to 3 keV, it was found that a virtually energy-independent shape of the electron distribution might be achieved even in a very broad range of electron energies (up to 15 keV) by appropriate selection of the operational high voltage of a channeltron. However, the efficiency of channeltrons was also found to depend on count rates, indicating one of the principal difficulties in comparing distributions recorded under different experimental conditions.
