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

MEYRIN, SWITZERLAND - APRIL 19: A general view of the ISOLDE Decay Station, a permanent setup at ISOLDE and is modular and can consist of gamma, beta and even proton or alpha particle detectors during a behind the scenes tour at CERN, the World's Largest Particle Physics Laboratory on April 19, 2017 in Meyrin, Switzerland. The Isotope mass Separator On-Line DEvice (ISOLDE) studies the properties of atomic nuclei, with further applications in fundamental studies, astrophysics, material and life sciences. It is a unique source of low-energy beams of radioactive nuclides that is delivered to various experimental stations (around fifty each year). Presently, more than 450 researchers are active at ISOLDE. (Photo by Dean Mouhtaropoulos/Getty Images)
