Final Report

The authors acknowledge the contribution that our late colleague and friend, Dr. Stéphane Claude, made to the technical leadership of the ALMA Band 3 project at NRC from its very beginning. It was under his direction that this ALMA Upgrade Project was initiated, but to everyone’s sorrow and regret, he did not live to see completed. We dedicate this report to his memory.
