摘要：

The STAR endcap electromagnetic calorimeter will provide full azimuthal coverage for high-P-T photons, electrons and electromagnetically decaying mesons over the pseudorapidity range 1.086 less than or equal to eta less than or equal to 2.00. It includes a scintillating-strip shower-maximum detector to provide pi(0)/gamma discrimination and preshower and postshower layers to aid in distinguishing between electrons and charged hadrons. The triggering capabilities and coverage it offers are crucial for much of the spin physics program to be carried out in polarized proton-proton collisions. (C) 2002 Elsevier Science B.V.
