Abstract

The BaBar experiment at the PEP-II electron-positron collider at SLAC has recorded more than 30 Tb of data in an Object Oriented database, and is expected to reach a data rate of 300 Tb/year. This data must be accessible to 400 physicists in 10 countries. We report on the design and initial experience with this system.

BaBar is among the first in a new generation of particle physics experiments pushing the limits of data storage and access technologies. We make mention of plans for future experiments, notably on the LHC at CERN, with storage requirements in the multi-Petabyte region.
