The ESRF (European Synchrotron Radiation Facility) at Grenoble is one of the most powerful synchrotron research facilities in the world. It produces and controls an extremely high-energy, focused X-ray beam that is used as a "super microscope" to examine the atomic structure of items in our larger world. The X-rays produced by this giant, circular synchrotron are nearly a trillion times more powerful than what is used for medical images, and are focused into beams narrower than a human hair. This panorama was shot inside one of the lead-lined "experiment cabins" that lay at tangents to the main synchrotron ring. The long metal tube extending to the right is what carries a portion of the circulating beam into the room, and specific equipment at this station allows that beam to be "tuned" to various wavelengths. At the end of the beam (and shown magnified on the screen above it) sits a frozen crystal of purified protein that will be exposed to the high energy beam to determine the atomic structure of the individual protein itself. Across from this, on the left side, is the large electron detector which functions as a giant digital camera to capture the X-ray diffraction patterns after they pass through the crystal. Because this room is exposed to the X-ray beam during experiments, most of the equipment you see is designed to be operated by remote control once the experiment is set up, and safety systems insure that no humans are inside when the shutter for the beam is opened. This panorama was taken while the beam was off, so the door is seen open, and much of the equipment is being taken offline after weeks of non-stop work. If you want to imagine the magnification of this "super microscope," zoom in on the tiny crystal being examined (a white speck where the metal tubes converge) and then use the Google Earth link (below) to "zoom way out" and see the synchrotron ring itself surrounded by the Vercors and Chartreuse mountains. Special thanks to Dr. Martin Walsh and Dr. Max Nanao of the BM14 CRG beamline for this rare view of a working experiment cabin. Behind the scenes : how this panorama was made
