View of part of the HERA accelerator at DESY (Deutsche Elektronen Synchrotron), Hamburg. HERA (Hadron Electron Ring Accelerator) consists of a pair of accelerator rings mounted in a circumference tunnel. The upper (cream-coloured) ring carries protons, whilst the lower (pink) ring carries electrons in the other direction. At two points on the ring the beams cross, providing proton/electron collisions at an energy of 850 GeV. Two large detectors (H1 and ZEUS) will study these collisions. It is hoped that data from these detectors will provide more information about the quarks inside protons and the gluon force moderators that bind them together.
