The X-ray pump-probe (XPP) instrument will predominantly use a fast optical laser to generate transient states of matter, and the hard X-ray pulses from the LCLS to probe the structural dynamics initiated by the laser excitation. The laser pump will have the ability to conduct precise optical manipulations, in order to create the desired excited states. The instrument design will emphasize versatility. To maximize the range of phenomena that can be excited, it will be necessary to be able to manipulate the laser pulse energy, frequency, and temporal profile. X-ray scattering will be the dominant tool for probing the laser-induced structural changes. These experiments require the union of four experimental capacities: the generation and delivery of X-ray and laser pulses to the sample, the preparation of the excited state in the sample, and the detection of the X-ray scattering pattern.
