ZEUS (particle detector)

ZEUS was a particle detector at the HERA (''Hadron Elektron Ring Anlage'') particle accelerator at the German national laboratory DESY in Hamburg. It began taking data in 1992 and was operated until HERA was decommissioned in June 2007. The scientific collaboration behind ZEUS consisted of about 400 physicists and technicians from 56 institutes in 17 countries.

The ZEUS detector comprised many different detector components, including a depleted uranium plastic-scintillator calorimeter, a central tracking detector (which was a wire chamber), a silicon microvertex detector and muon chambers. In addition, a solenoid provided a magnetic field. The ZEUS detector measured 12 m × 11 m × 20 m and weighed 3600 tons.

Like its partner experiment H1, the ZEUS experiment studied the internal structure of the proton through measurements of deep inelastic scattering by colliding leptons (electrons or positrons) with protons in the interaction point of ZEUS. These measurements were also used to test and study the Standard Model of particle physics as well as to search for particles beyond the Standard Model, laying the foundation to much of the science done at the Large Hadron Collider (LHC) at the CERN particle physics laboratory today.
