Concept for an experiment on particle and jet production at midrapidity

The concept for an experiment to study global event signatures of quark Gluon Plasma formation and to investigate the propagation of jets through strongly interacting matter at high density is presented. Both event-by-event and inclusive measurements of physical observables can be made at midrapidity over a large solid angle ({vert bar}{eta}{vert bar}<1) with full azimuthal coverage ({Delta}{phi} = 2{pi}) and azimuthal symmetry. The detection system consists of a vertex detector and time projection chamber (TPC) inside a solenoidal magnet for tracking, momentum analysis and particle identification; a time-of-flight system surrounding the TPC for particle identification at higher momenta; and electromagnetic and hadronic calorimetry to measure and trigger on jets and the transverse energy of events. 7 figs., 2 tabs.
