The Front-End Driver Card for the CMS Silicon Strip Tracker Readout
نویسندگان
چکیده
The first prototypes of the production version of the Front-End Driver (FED) card for the CMS silicon strip tracker are about to be manufactured. The FEDs provide the off-detector processing of the tracker readout system. They digitise and zero-suppress the multiplexed analogue optical data sent on each Level-1 trigger from the ondetector APV25 pipeline chips. This paper outlines the design and describes in detail the implementation of the 96 ADC channel, 9U VME64x form factor card. In total, 440 FEDs will be required to readout the silicon strip tracker.

The CMS Silicon Strip Tracker: System Tests and Test Beam Results
With a total area of 210 squaremeters and about 15000 single silicon modules the silicon strip tracker of the CMS experiment at the LHC will be the largest silicon strip detector ever built. While the performance of the individual mechanical and electronic components has already been tested extensively, their interplay in larger integrated substructures also has to be studied before mass produc...
متن کاملDouble-sided Silicon Detectors using N-side Pad Readout for the CMS Silicon Inner Tracker
Double-sided silicon detector prototypes produced for the CMS inner tracker are described which divide the n-side into pads rather than strips. The signal routing to the readout electronics is made on a separate flexible z-print which is glued on the detector and then wire-bonded to the pads.
متن کاملDesign of the LHCb Silicon Tracker∗
The LHCb Silicon Tracker is a large-surface silicon micro-strip detector that will cover an important part of the LHCb tracking system. Its data will be used in the trigger to select high-pT daughter particles from B-meson decays, and in the offline analysis to reconstruct trajectories of charged particles in the very forward region of the detector. Readout strips of up to 38 cm in length with ...
متن کاملThe electronic readout of the CMS tracking system
A description is given of the electronic readout system proposed by the CMS experiment for the microstrip tracker. It is an analogue system based on a front end chip development by RD20 and analogue optical links being developed by RD23. Both gas and silicon microstrips are read out by the same system with minor modifications to the front end chips to accommodate the different detector characte...
متن کاملThe CMS Silicon Strip Tracker
The CMS collaboration is constructing the largest silicon tracker ever built with an active silicon area of 200 m2 to provide robust charged particle tracking and vertex reconstruction within the 4T magnetic field of the CMS Solenoid. The design of the detector, the status of the construction and the performance of the substructures are reviewed. PACS: 29.40.Wk, 29.40.Gx, 01.30.Cc THE CMS SILIC...
