The CLEO-III trigger system

The CLEO-II experiment is presently accumulating data at the Cornell Electron Storage Ring (CESR). The superb performance of CLEO and CESR has made this laboratory a world leader in the study of heavy quark physics. Over the next two years this facility is embarking on an ambitious program to upgrade both the detector, which will become “CLEO-III”, and the storage ring, whose luminosity will be increased tenfold, A detailed discussion of the design parameters for the CLEO-III trigger and data-acquisition systems are given in the CLEO-III Detector Proposal. A brief introduction to the system requirements is given, followed by more in-depth descriptions of several specific trigger system components
