Figure 7
Distribution of X-ray pulse arrival times measured with the THz streaking time tool at SwissFEL. The histogram in blue contains arrival times corrected for uncorrelated drift and for the THz calibration systematic error, the histogram in orange contains unstreaked raw Xe 3s photoelectron energies converted to femtoseconds using the corrected THz time tool calibration. The solid lines mark fitted Gaussian curves. The bin width is equal to 2.5 fs. |
