Alignment of the ATLAS Inner Detector tracking system
The Large Hadron Collider (LHC) at CERN is the world largest particle accelerator. It will collide two proton beams at an unprecedented center of mass energy of 14 TeV. ATLAS is equipped with a charge particle tracking system built on two technologies: silicon and drift tube based detectors, composing the ATLAS Inner Detector (ID). The alignment of the tracking system poses a challenge as one s...
متن کاملAlignment data streams for the ATLAS Inner Detector
The ATLAS experiment uses a complex trigger strategy to be able to reduce the Event Filter rate output, down to a level that allows the storage and processing of these data. These concepts are described in the ATLAS Computing Model which embraces Grid paradigm. The output coming from the Event Filter consists of four main streams: physical stream, express stream, calibration stream, and diagnos...
متن کاملThe ATLAS Inner Detector
A DESCRIPTION OF THE ATLAS detector is given in the previous article by George Trilling. Twenty-eight U.S. universities and three national laboratories comprise about 20 percent of the ATLAS (A Toroidal LHC ApparatuS) collaboration, the largest single national group. U.S. physicists are involved in essentially all aspects of the ATLAS experiment, but I will only describe here one area of activi...
متن کاملTrack-based detector alignment for PET scanners
Department of Physics of Molecular Imaging Systems, Institute for Experimental Molecular Imaging, RWTH Aachen University, Aachen, Germany For sub-millimeter PET the precise spatial location of each line of response (LOR) is crucial. Physical misalignments of detector modules, if not properly accounted for, can significantly degrade the spatial resolution. In this work, we investigate the applic...
متن کاملParticle Tracking in the ATLAS Inner Detector
The Hough transform [1] has recently received much attention as a powerful method of track finding in particle detectors. It has the strength of detecting track segments without having to put in much prior information about the location of the track segments. We present here an alternative algorithm where we show in a specific case how prior information of the tracks can be used to modify the H...
