Abstract

The CMS Electromagnetic Calorimeter consists of roughly 76000 lead tungstate (PbWO4) crystals and almost 25000 Printed Circuit Boards (PCBs) of 5 different types. About 5500 Gigabit Optical Links are used to process the signals from the photo-detectors and to send the resulting data to the off-detector electronics. The integration of the electronics is described together with its cooling system, mechanical supports, the low voltage distribution, various signal cables and optical fiber patch panels. Complexity and installation sequence require tests at each step of the installation. The test strategy during the installation is described and results of the system performance achieved are presented.
