image: This shows the inside of the experimental chamber showing the spectrometer (front) and the detector (black rectangle in the back) used for the detection of the X-ray emission spectra, and the glass fiber used for illumination of the sample (green). The sample is injected from the top and the X-rays enter the chamber from the right. 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
