The BaBar experiment's computing resources are geographically spread out. A direct consequence of this is that a large amount of data is transferred between sites. Providing easy management and access to these data is a challenging task. To accomplish this task we are employing the storage resource broker (SRB), developed at the San Diego Super Computing Center, to manage the BaBar data files and to replicate them between Tier-A centers. The system has been tested between the computing centers l'Institut National de Physique Nucléaire et de Physique des Partictiles (CC-IN2P3), Lyon, France, and at Stanford Linear Accelerator Center (SLAC), Menlo Park, CA, and this paper discusses our experience with a view to production use. We describe how the system could be used to manage the data import/export between the computing sites and how it fits into building a BaBar data grid. We also explain how a user benefits from this system to access and obtain data in an easy and transparent fashion. [ABSTRACT FROM AUTHOR]

The article presents the author's comment on the "2004 IEEE Nuclear and Space Radiation Effects Conference." The December 2004 special issue of the IEEE Transactions on Nuclear science contains selected papers from the 41th Annual Nuclear and Space Radiation Effects Conference, held in Monterey, California from July 19-23, 2004. Over 100 papers from the conference were submitted to the Guest Editor for consideration for year's special issue. This publication is the premier archival journal of research on space and nuclear radiation environments and effects on materials, devices, circuits and systems.
