A section of the 27Km circular tunnel beneath the French-Swiss border near Geneva. The tunnel carries the Large Hadron Collider particle accelerator which houses two beams of protons,within separate high-vacuum pipes,travelling in opposite directions,kept on an accurate path by dipole super-conducting electromagnets,cryogenically chilled to -271.3ºC by liquid helium. Photographed during the 2013 shutddown,with the main vacuum pipe open for maintenance work | |
