ATLAS Semiconductor Tracker (SCT) and Inner Detector (ID)

ATLAS Semiconductor Tracker (SCT) and Inner Detector (ID)

The ATLAS ExperimentATLAS is a general purposed CERN LHC-based detector designed to take full advantage of the very high energy (14TeV), high luminosity (1034cm-2s-1) proton-proton collisions of the LHC. ATLAS will be able to study the properties of the Higgs boson in a range of decay modes. ATLAS will also be sensitive to other exotic phenomena, such as: supersymmetry, extra dimensions, quark compositeness, and as yet unthought-of physics. At the heart of the ATLAS experiment is the inner detector (ID), which is composed of the Pixel, Semiconductor tracker (SCT) and transition radiation tracker (TRT).

The Glasgow group have been involved from the start of the ATLAS experiment's inception.  The group's hardware activities date from the CERN RD collaborations, set-up to study new technologies for the LHC experiments. They continued through a SCT and ID design and prototype stage; a production phase for SCT forward modules and power tapes, and ID cooling studies and prototyping; via the integration, installation and commissioning of the SCT and ID into the ATLAS experiment; to finally what one hopes will be a fruitful exploitation of the apparatus. The group remains involved in the maintenance and operation of the ATLAS SCT and ATLAS ID. The group's important hardware contributions to the ATLAS experiment in both the SCT and ID are given here:
