Technician in OPAL detector, CERN

A technician works on one of two end caps of the OPAL detector at CERN, the European centre for particle physics near Geneva. OPAL 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. OPAL is a cylindrical assembly of many types of apparatus which fit together like an onion around the point where the particles collide. The OPAL end caps consist of pre-shower counters (the "spokes" of the wheel) & electro-magnetic & hadron calorimeters. The technician is Martin Sproston of the Rutherford Appleton Laboratory in Britain. Photo taken April 1989

Geopelia cuneata
Found in large areas of Australia except to the south. Largely a bird of the dry interior but moves to coast in times of drought. Inhabits grassy and spinifex woodlands and dry scrublands. Never far from water.
