Abstract

This thesis describes a 16-bit parallel pipelined processor which is used in a Fermilab fixed-target heavy-quark experiment (E789). E789 is an experiment to study two-prong dihadron decays of neutral beautyquark (6) hadrons produced in 800-GeV proton-nucleus interactions. The results of the experiment will be used to constrain the Kobayashi-Maskawa (KM) matrix. Chapter 1 discusses the general background and the experimental objectives. Chapter 2 describes the E789 apparatus. The trigger processor is designed to reconstruct complex multiparticle events in about 10 /a s . The processor consists of an upstream vertex processor, a downstream track processor, and a vertex “end game” . A total of 105 functional modules of 12 types are used in the processor. Chapter 3 discusses the structure and operating principles of the processor. The author contributed to designing, building, and debugging the trigger processor. A module test program and a cable test program designed by the author are discussed in Chapter 4. These programs test all processor module types and the intermodule cabling.
