Behind The Scenes At CERN The World's Largest Particle Physics Laboratory

MEYRIN, SWITZERLAND - APRIL 19: A general view of MEDICIS which is under construction during a behind the scenes tour at CERN, the World's Largest Particle Physics Laboratory on April 19, 2017 in Meyrin, Switzerland. MEDICIS (Medical Isotopes Collected from ISOLDE) is a research facility at CERN that will make radioisotopes for medical applications. The facility will use a proton beam at ISOLDE to produce the isotopes, which are first destined for hospitals and research centres in Switzerland, and will progressively extend to a larger network of laboratories in Europe and beyond. Such isotopes are used in medicine to highlight specific cells for imaging, or to target them for destruction. (Photo by Dean Mouhtaropoulos/Getty Images)
