Abstract :
We have designed and built a trigger processor that determines the number of isolated showers deposited in the electromagnetic calorimeter of the KTeV detector. Our algorithm takes advantage of pattern recognition and parallel processing techniques to increase its speed relative to more conventional cluster finding algorithms. With a relatively modest clock speed of 20 MHz, this processor reaches a decision in under 2 μs.
