ARLINGTON - The appointment of University of Texas at Arlington Physics Professor Kaushik De to be the U.S. ATLAS Operations Coordinator became effective April 1. The ATLAS is one of four detectors to be located at a powerful new accelerator, the Large Hadron Collider, now under construction near Geneva, in Switzerland. More than 500 physicists, engineers and graduate students from 43 United States institutions participate in the ATLAS collaboration. These scientists represent 39 universities and four Department of Energy national laboratories. The whole ATLAS collaboration includes 1,900 participants from 35 countries.

The announcement noted that De has been leading the ATLAS Monte Carlo production effort on an international scale for several years. He has made several important contributions to the development of ATLAS production systems, most notably PanDA, which has been recently chosen to be the common system for production throughout ATLAS. De will be responsible for coordinating Computing Operations at U.S. Tier 1 and Tier 2 facilities. This includes services required for Monte Carlo production, data re-processing, user analysis, databases, and overall data management. He will also chair the U.S. Resource Allocation Committee.

As the U.S. Operations Coordinator, De will be the primary contact person in interactions with ATLAS Distributed Computing Management, to schedule common operations activities in the areas of production and distributed analysis. De will closely work with the Facility Integration Program, led by Robert Gardner from University of Chicago, to implement the required functionality and capacities. He will be leading the United States’ participation in major ATLAS activities, involving many experts from the U.S. teams at Tier 1 and Tier 2 facilities.

The U.S. ATLAS collaboration will contribute $163.74 million to the construction of the ATLAS detector by the end of 2008. United States groups have contributed components to all of the ATLAS detector subsystems, each dedicated to measuring different properties of different types of particles. Scientists from the United States have also contributed to the development and testing of the data acquisition system, which takes the raw data from the ATLAS detector, filters it, and stores it in a form that physicists will use to search for and measure fundamental particles and forces.

Major components of the ATLAS detector were built at UT Arlington and are now installed at the European Organization for Nuclear Research (CERN), near Geneva. UT Arlington is one of five Tier 2 supercomputing centers in the United States, which will be used by all ATLAS physicists to search for new physics at the Large Hadron Collider. De will be coordinating the Tier 1 and Tier 2 computing centers deployed in the United States to process the patabytes of data expected soon.
