“…The laser drivers have four different gain settings which can be used to account for difference in the transmission gain of the individual links. The data are transmitted over a distance of about 100 m, out of the experimental cavern to the Front End Driver (FED) units [4] for further processing. The CMS strip tracker has a total of 440 FEDs which process the data from 96 fibers each.…”

The CMS silicon strip tracker is the largest silicon detector ever built with almost 10 million readout channels and an active area of close to 200 m 2. With more than 15,000 individual microstrip silicon modules are powered by almost 1000 power supply modules and produce more than 60 kW of power while operating at low temperatures. Results from the successful operation of the tracker at the first LHC collisions at 0.9, 2.4, and 7 TeV, including environmental control, calibration, detector performance, and monitoring, are discussed. The detector performance is excellent manifested in a nearly 100 % functional tracker with high single hit efficiency, good S/N performance, and high quality track resolution. This is made possible by a fine-grained calibration process and a monitoring of all important quantities for the detector performance during different stages of the operation.

The CMS tracker is the largest silicon detector ever built, covering an area close to 200 m 2 and consisting of 15 148 silicon strip and 1440 silicon pixel modules. The use of tracker data in physics analysis requires fine-grained monitoring and calibration procedures. Results from timing studies, threshold optimization, calibration of gains and Lorentz angle determination are shown and the impact on resolution and dE/dx measurements is discussed. In order to achieve an optimal track-parameter resolution, the position and orientation of its modules need to be determined with a precision of few micrometers and an accurate representation of the distribution of material in the tracker is needed. Results of the alignment of the full tracker are presented, based on the analysis of several million reconstructed tracks recorded during the commissioning of the CMS experiment with cosmic rays and the first proton-proton collisions. They have been validated by several data driven studies and compared with predictions obtained from a detailed detector simulation. Reconstructed photon conversions and nuclear interactions have been used for a first estimate of the tracker material.

“…The major components of the SST readout system [1] are: 15 148 front-end printed boards that host 72 784 APV25 [4] readout chips, an analogue optical link system comprising 36 392 individual fibers [5], and 440 off-detector analogue receiver boards, known as Front-End Drivers (FED) [6]. The SST control system [7] is driven by 46 off-detector digital transceiver boards, known as Front-End Controllers (FEC) [8].…”
