Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics

A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together with the performance of b-tagging and the trigger. The physics potential for a variety of interesting physics processes, within the Standard Model and beyond, is examined. The study comprises a series of notes based on simulations of the detector and physics processes, with particular emphasis given to the data expected from the first years of operation of the LHC at CERN

Recent trends in 3D detectors

A new type of 3-D sensor has been developed using double sided processing with the aim of simplifying the production process. The results of strip and pixel devices from the first production run are presented. The devices fully deplete at 8 V. Tests on a beamline at the Diamond Synchrotron demonstrate much reduced charge sharing in the 3-D devices compared to planar devices. 3-D sensors also potentially have application in the harsh radiation environment of the LHC experiment upgrades. The optimal spacing between electrodes for this application has been simulated, and a cell dimension of 50-100 µm found to be optimal. The work is placed in the context of other types of 3-D architecture detectors and the work of other groups on the commercial fabrication of devices is briefly reported

The ATLAS Experiment at the CERN Large Hadron Collider

The ATLAS detector as installed in its experimental cavern at point 1 at CERN is described in this paper. A brief overview of the expected performance of the detector when the Large Hadron Collider begins operation is also presented
