DELPHI (DEtector with Lepton, Photon and Hadron Identification) is a detector for e+e− physics, designed to provide high granularity over a 4π solid angle, allowing an effective particle identification. It has been operating at the LEP (Large Electron-Positron) collider at CERN since 1989. This article reviews its performance.
