摘要
The OPAL detector at the e+e- storage ring LEP is designed to provide precise measurements of charged particles and of electromagnetic energy over nearly the full solid angle. Its main elements are a central tracking system, a solenoidal coil, an electromagnetic calorimeter made of lead glass, a hadron calorimeter made of iron and wire chambers, and a muon detector. A pair of forward detectors is used to measure the luminosity and to identify particles emitted at small angles with respect to the beam line. In this paper all detector elements are described and their performance is discussed.
