(a) Average pulse energies and intensity fluctuations as a function of undulator length for the second and third harmonics of the XFEL beam that transmitted the prism and those for fundamental radiation in OH. (b) XFEL beam profiles in EH5 that transmitted the prism [(left) L = 10 m, (middle) L = 20 m] and without the prism [L = 105 m] (right). |
