The experimental high energy physics group at MSU was a member of the initial group of US institutions that joined the ATLAS experiment in 1994.  Our ATLAS group presently consists of six senior physicists (faculty and researchers), three postdocs, two engineers, two graduate students and two undergraduates.  We expect to add more students as the LHC becomes operational.

During the last few years we have been involved in the design, construction, installation and commissioning of two distinct items for the ATLAS detector; the Tile Calorimeter and the High Level Trigger.  The Tile Calorimeter, many of whose modules were instrumented in the labs of MSU before being shipped to CERN, will contribute to the accurate measurement of the energies of particles emerging from the collision region.  The High Level Trigger is part of a fast, custom-built system, based on electronics and PCs, designed to select potentially interesting events from a large background.

Michigan State University, in collaboration with colleagues at the University of Michigan, is also home to a high density Grid computing center (ATLAS Great Lakes Tier-2 Center).  We expect to make a major contribution to the processing of the large quantity of exciting data that will be produced by the ATLAS detector.

Our group is also contributing to the physics program being investigated by the ATLAS collaboration.  Following our work at the Fermilab collider, we are playing a significant role in the Top physics group, particularly interested in the production of single Top quarks.  We are also working on establishing Standard Model benchmarks with early data sets, especially the production of W and Z boson events with jets, and in developing versatile tools for the reconstruction of jets.  We are eagerly awaiting the exciting new physics opportunities that will be opened up by the LHC accelerator and the ATLAS detector.
