Front-end electronics, triggering, and data acquisition

In this section we examine the ramifications of luminosities () between and on the CLEO front-end electronics, trigger, and data acquisition systems. We briefly review the present status of these systems and the implications of their unmodified use at in view of the expected backgrounds. Trigger and front-end architectures applicable to high luminosity operation are discussed, and a data-acquisition system having sufficient bandwidth and flexibility is presented. Since we are designing a new electronics architecture that will be in use beyond the initial CESR Phase 3 upgrade, it must be extensible to , the upper limit that CESR can achieve.
