(a) Trend plot of XFEL pulse energies (left axis) and positions (right axis) measured with the monitor in a pulse-by-pulse manner. A pulse energy of 100 µJ corresponds to 6 × 1010 photons per pulse. (b) Transmitted coherent X-ray image of the nanocrystal diamond foil in the monitor. Signal intensities over the 450 × 450 pixels have a standard deviation of only 2% of the average. Cross-sectional profiles along the dotted lines are shown. |
