The LHC is installed in a tunnel ranging from 50 to 150 metres underground. Particle detectors called Alice, Atlas, CMS and LHCb surround the points at which particles collide, measuring the emerging showers of particles. The tunnel crosses the French-Swiss border six times, with the particle beams making 66000 border crossings per second.
