Twenty years ago a new then electron proton collider was commissioned in the Deutsches Electron Synchrotron Laboratory (DESY) in Hamburg, Germany. This collider, HERA, had the unique feature of accelerating two particle species in two different directions and colliding them headon. With a proton energy of 820 Gev and an electron energy of 28 GeV it provided the conditions for studying the so called deep inelastic scattering processes, by employing electrons as bullets to reach deep into the target proton interior. Four experiments around the HERA circumference recorded and studied the collisions. The university of the Aegean physics group participated in one of them, the experiment ZEUS. An overview of ZEUS physics results can be found here.  HERA and ZEUS were decommissioned in 2007.
