The ATLAS experiment will study pp collisions at a centre of mass energy of 14 TeV at the Large Hadron Collider (LHC) at CERN. This high energy combined with the very high luminosity will allow ATLAS to make a detailed investigation of the phenomena associated with the scale of electro-weak symmetry breaking, referred to as the Terrascale. A broad range of physics topics is accessible at the LHC and participation in this program is regarded as an essential ingredient of the future Canadian HEP program. The approval of an in-kind accelerator contribution from TRIUMF to the LHC was a necessary and important step for the ATLAS group.
The Canadian ATLAS group has been an active contributor to ATLAS since the formation of the collaboration. The team is comprised of phyicists from Alberta, Carleton, McGill, Montreal, Regina, Simon Fraser, TRIUMF, Toronto, UBC, Victoria and York. There are more than 150 CAnadian physicists involved, including 40 senior scientists.
The detector projects are concentrated on the liquid argon calorimeters of ATLAS, with contributions to the hadronic endcap and the forward calorimeters and associated front end electronics and cryogenic feedthroughs for these devices. The construction of all of these components is now complete and they are at CERN. The IPP ATLAS group is also carrying out radiation damage measurements, leading the effort to monitor the beam conditions and detailed simulation studies of the performance of all of these detectors for physics processes at the LHC. ATLAS is scheduled to begin high energy data-taking in 2009. For more information, see www.atlas-canada.ca
