Sumario: | The CMS Silicon Barrel Detector is a subsystem of the CMS Tracker and consists of seven wheels. For the SiB1-Milestone, that was completed in Summer 1997, one of these wheels has been built and equipped with 14 working silicon microstrip detector modules and 112 dummy modules. The working modules consist of two detectors glued together each one having 1024 strips with a pitch of 50 micron that are read out by eight PreMux 128 Chips. In the dummy modules the Readout Electronics have been substituted by resistors simulating the heat load. The dummy silicon sensors have fiducial marks and were alligned with a precision of 5 micron. The supporting wheel structure is made out of carbon fiber and incorporates all services. The assembly precision of the support structure was better than 100 micron. |
