TOB Module Assembly and Testing Project


All 5208 modules of the CMS Tracker Outer Barrel were assembled and tested at two production sites in the US: the Fermi National Accelerator Laboratory and the University of California at Santa Barbara. The modules were delivered to CERN in the form of rods, with the last shipment taking place in August 2006. The 688 rods were then inserted into the TOB wheel by the integration team at CERN. The institutes that participated in the TOB module and rod assembly and testing included Brown University, Fermilab, Kansas State University, the University of Kansas, the University of Illinois at Chicago, UC Riverside, Rochester University, UC Santa Barbara, and three groups from Mexico (Cinvestav, Puebla, and San Luis Potosi). The US CMS SiTracker group also contributed to the TOB integration effort and the Tracker Integration Facility Sector Test, and is currently participating in the commissioning and monitoring of the CMS Tracker at Point 5 as well as R&D for a possible upgrade of the Tracker for Super-LHC.
