摘要：

The Crystal Barrel spectrometer used at LEAR, CERN to study the products of ppBAR and pdBAR annihilations is described. A 1380 element array of CsI crystals measures photons from the decay of pi0, eta, eta' and omega mesons. A segmented drift chamber in a 1.5 T magnetic field is used to identify and measure charged particles. A fast on-line trigger on charged and neutral multiplicities and on the invariant mass of secondary particles is available. The performance of the detector is discussed.
