Performance of the CDF neural network electron isolation trigger at Fermilab

Abstract
The performance of the CDF isolated endplug electron trigger in the 1993 run of the CDF experiment is presented. The trigger was designed to select events in pp interactions containing isolated electromagnetic clusters in the endplug calorimeter. The trigger was found to be 97% efficient for electrons from W decays in the range of rapidity covered by the trigger, and to provide a background rejection of a factor of 3. The neural network chip used to perform the isolation calculation exhibited no problems with reliability or stability during 8 months of running.
