Interesting ESRF FactsThe European Synchrotron Radiation Facility is funded by 17 European countries and Israel, and is used by 3500 researchers each year for experiments in every aspect of science.
The high-security campus for the synchrotron lies at the confluence of the Drac and Isere rivers in the southeast corner of France, at the foothills of the French Alps. ("Foothills" here can mean 2400 meters tall!)
The electrons emitted by the main electron gun are accelerated to reach an energy level of 6 billion electron-volts (6 GeV), and the power to do all of this is provided by a dedicated power plant on the campus.
The main synchrotron is a large (844 meters in circumference) storage ring where electrons circulate in a vacuum, at a constant energy, before being diverted into some of the 40 beamlines.
600 people work at the ESRF to maintain the facility, assist visiting researchers, develop new technologies, and carry out their own experiments.
Behind the scenes : how this panorama was madeThe panoramic rig was set up on a carbon-fiber tripod with two legs collapsed and extended at near horizontal on the sample mounting area, with the third leg going off the edge of the table onto the floor.
The Agnos panoramic head and my camera take up very little room when rotating, so the 3 photos were simply taken with a timer (so no shadows would be visible) and a pause to rotate the head between each shot.
The images were stitched together with PTMac and blended with Enblend, with some minor retouching to the seams. The hardest part was cloning the tripod out of the photographs since it spread across most of the table - and I forgot to take a "down" shot! Thank heaven for Photoshop...
