ATLAS Silicon Microstrip Semiconductor Tracker (SCT)
The large hadron collider (LHC) is under construction at CERN, using the existing LEP tunnel of 27 km circumference, in order to accelerate protons to 7 TeV and to make head-on collisions at the center-of-mass energy of 14 TeV with a luminosity of 10 34 cm -2 s -1 [1]. The ATLAS detector, one of the two major general purpose detectors in LHC, was approved as an experiment in 1994 and is planned...
متن کاملRadiation Hardness Studies of the Front-end ASICs for the Optical Links of the ATLAS SemiConductor Tracker
Studies have been performed on the effects of radiation on ASICs incorporating bipolar npn transistors in the AMS 0.8 μm BiCMOS process. Radiation effects are reviewed and the approach used to achieve radiation tolerant ASICs is described. The radiation tests required to validate the ASICs for use in the ATLAS detector at the CERN Large Hadron Collider are discussed. The results demonstrate tha...
متن کاملThe Off-Detector Opto-electronics for the Optical Links of the ATLAS SemiConductor Tracker and Pixel Detector
The off-detector part of the optical links for the ATLAS SCT and Pixel detectors is described. The VCSELs and p-i-n diodes used and the associated ASICs are described. A novel array packaging technique is explained and an analysis of the performance of the arrays and the overall system performance is given. The proposed procedure for the set-up of the optical links in ATLAS is described. PACS: ...
متن کاملATLAS Transition Radiation Tracker test-beam results
Several prototypes of the Transition Radiation Tracker for the ATLAS experiment at the LHC have been built and tested at the CERN SPS accelerator. Results from detailed studies of the straw-tube hit registration efficiency and drifttime measurements and of the pion and electron spectra without and with radiators are presented. r 2004 Elsevier B.V.

متن کاملA Study of Geodetic Grids for the Continuous, Quasi Real Time Alignment of the Atlas Semiconductor Tracker
An alignment system based on Frequency Scanning Interferometry has been developed to monitor shape changes of the ATLAS semiconductor tracker. Movements of the detector modules will be monitored in quasi real time by combining precise distance measurements between nodes of a geodetic grid attached to the support structure. The final geodetic grid will consist of eight hundred lines of sight in ...
