Abstract
The Semi-Conductor Tracker (SCT) is one of the key precision tracking devices in the ATLAS experiment at CERN Large Hadron Collider (LHC). The SCT was constructed of 4088 modules for a total of 6.3 million silicon strips and was installed into the ATLAS experiment in 2007. The SCT has been fully operational since then, and achieves a good tracking performance from the startup of the LHC operation.
Highlights
LHC delivered an integrated luminosity of 5.6 pb-1 at in 2010-2011 The SemiConductor Tracker (SCT) is constructed of 4088 silicon detector and more than 12 pb-1 at in 2012
ATLAS is one of two multi-purpose detectors in LHC consists of ✓The inner detector: a large precise tracking system operated in 2.0T
Solenoid magnet. ‣ the Pixel detector. ‣ the SemiConductor Tracker (SCT). ‣ the Transition Radiation Tracker (TRT). ✓The calorimeters. ✓The muon spectrometers operated with 3.9T toroid magnets
Summary
LHC delivered an integrated luminosity of 5.6 pb-1 at in 2010-2011 The SCT is constructed of 4088 silicon detector and more than 12 pb-1 at in 2012. ATLAS is one of two multi-purpose detectors in LHC consists of ✓The inner detector: a large precise tracking system operated in 2.0T solenoid magnet. ✓The muon spectrometers operated with 3.9T toroid magnets. Modules for a total of 6.3 million strips. The modules are mounted into two types of structures:. ✓One barrel (4 cylinders at radius from 299 to 514 mm with a tilt angle of 11°, 2112 modules). 4 types of modules, 1976 modules in total). Each module is designed, constructed and tested to operate as a standalone unit, mechanically, electrically, optically and thermally
