A technician works on cabling inside the "support tube" of the L3 detector at CERN, the European centre for particle physics near Geneva. L3 is one of 4 giant particle detectors at the LEP collider. LEP collides electrons & positrons accelerated to an energy of 50 GeV in a circular tunnel 100m underground & 27km in circumference. A collaborat- ion of 460 physicists from 13 countries, L3 is a cylindrical assembly of many types of apparatus which fit together like layers of an onion around the point where the particles collide. Behind the technician in this photo can be seen the 261- ton, ring-shaped Hadron Calorimeter on which 3 other people are working beneath the yellow gantry. Photo taken April 1989.
