The Grounding and Shielding\\ of the\\ Tracker Inner Barrel and Disks (TIB/TID)

During the construction of the CMS silicon strip tracker, one of the issues addressed was that of the grounding and shielding of the detector. The complexity of the system was unprecedented, with many issues requiring careful consideration before a full solution could be found. In particular, the problems encountered and the solutions adopted for the silicon Tracker Inner Barrel and Disks (TIB/TID) will be described. Since this work the TIB/TID has been integrated with the rest of the CMS Tracker and has participated in cosmic ray studies, both above ground with the full Tracker and below ground with the full CMS detector. Throughout these studies the noise performance has been consistent with that of the as-delivered system.
