Schematic layout of the Aramis Bernina pump/probe instrument including selected elements. The pump laser source can be converted to different energies and pulse lengths for exciting a specimen. Part of it is used to measure the time delay with respect to the X-ray pulses from the Aramis FEL. The X-ray beamline consists of a set of monochromator crystals as well as beam steering and focusing optics. The X-ray pulse spatial profile, position and intensity are measured at multiple positions in the beamline. The experiments can be carried out at multiple endstations which can be translated into the focused FEL beam. |
