(a) The average pulse power profile (black line) and final power profiles distribution of 260 shots (gray line). (b) The farfield Wigner distribution for a typical pulse. The normalized power (red solid line) and spectrum intensity (green solid line) distribution are also displayed. (c) The statistical results for evolution of mean peak power (blue line) and FWHM duration (red line) of 260 pulses shots along the undulator beamline. (d) Average farfield spectral intensity (green line) of the 260 pulses (background image) at the exit of the undulator beamline. |
