Demonstration of the long-term stability of the energy calibration at ISS at low and high energies. (Left) Comparison of the spectra recorded on Co foil over the span of 24 h. The inset zooms on the data around the edge region where the derivative of the absorption coefficient is at its maximum. The horizontal bar shows the energy scale of the inset. (Right) Comparison of the spectra recorded on Pd foil with a time difference of 24 h. The inset focuses on the edge region of Pd as in the left panel. |
