Comparison of a raw ADC trace of a single-shot spectrum of a certain bunch number in the pulse train with its reconstruction derived from the PCA analysis. The data are from a measurement with argon at = 52.0 nm with pulse trains of 80 bunches. The upper panel shows the full TOF range of the spectrum block of bunch number
#!b = 21, whereas a TOF interval around the Ar 3p photoemission line is magnified in the lower panel. The spectrum belongs to the first block of 10000 shots which were used for PCA basis determination. |
