image: This shows the experimental chamber with the large access door open. The X-rays travel from the right to the left, and the X-ray spectrometer is located in the front. The sample is injected from the top and illuminated by an optical laser. The detector for the X-ray diffraction is located on the left (outside the view area). This image relates to a paper that appeared in the Feb. 14, 2013, issue of Science Express, published by AAAS. The paper, by Jan Kern at Lawrence Berkeley National Laboratory in Berkeley, CA, and colleagues was titled, “Simultaneous Femtosecond X-ray Spectroscopy and Diffraction of Photosystem II at Room Temperature.” view more
