The Coherent X-Ray Imaging (CXI) instrument will make use of the unique brilliant hard X-ray pulses from LCLS to image single sub-micron particles and determine the structure of biomolecules using nanocrystals. The near complete transverse coherence of the LCLS laser could allow single particles to be imaged at high resolution while the short pulse duration will limit radiation damage during the measurement. The instrument will allow imaging of biological samples beyond the damage limit that cannot be overcome with synchrotron sources. Samples can be introduced to the x-ray beam either fixed on targets or using a particle injector that will deliver free-standing particles or samples in a liquid jet to the beam. High quality focusing optics will generate three foci (10, 1 and 0.1 micron). The CXI instrument, while primarily designed to perform Coherent Diffractive Imaging experiments, will offer a flexible set of instrumentation suitable for a variety of experiments not limited to imaging or nanocrystallography. The CXI instrument is located in Hutch 5 of the Far Experimental Hall of LCLS. The hutch is 20 m long by 7 m wide. The CXI instrument is located 440 m away from the LCLS source.
