A Fast Cluster-Finder for the Fermilab Collider Detector Jet Trigger

A general circuit has been designed for finding clusters in arrays of arbitrary dimension and regularity. A cluster is defined to be a contiguous group of elements of an array each containing logical "true" signals, surrounded by elements of the array containing logical "false" signals. This circuit has been adapted to the particular geometry of the Collider Detector Facility (CDF) to find clusters of energy in a two-dimensional rectangular array of calorimetry. The performance of the circuit has been studied in this application using monte carlo simulation.
