Differences of the values of the photon energy and . has been derived by applying the standard wavelength monitoring analysis based on a line profile fit procedure to the original raw ADC traces. has been calculated converting the TOF values determined by center of gravity positions of the prompt signal and the Ar 3p photoemission lines with the existing time-to-energy calibration function. The photon energy result for a single shot i was determined from a moving average spectrum of the 21 shots [i − 10, i + 10]. Upper panel: of 9992 single shots for all bunch numbers. Lower panel: histograms of for each bunch number. Note that the plot ranges for are ten times larger compared with Fig. 11. |
