8. 9. Completed in 1976, the 7 km-long Super Proton Synchrotron (SPS) was the first giant underground ring to cross the Franco-Swiss border. Today, it accelerates particles before feeding them to the Large Hadron Collider (LHC): a 27 km ring buried 100 m below ground, housing two high-energy particle beams travelling in opposite directions. A crowdsourcing project CERN has accumulated about a quarter of a million hard-copy images that are currently being digitized, but which often lack information. It has asked its community to help tag people, instruments, and dates. http://cern.ch/go/tG03Ta The entire photo gallery 60 years of instruments at CERN is available online: www.cnrs.fr/cnrsmagazine 7 8 9 7. The Intersecting Storage Rings (ISR)—the first proton collider in the world—operated between 1971 and 1989. Made up of two identical 300-meter rings that intersect at 8 points, the machine, whose beams were supplied by the Proton Synchrotron (PS), helped provide hints that protons were composed of smaller parts.
