The BaBar electromagnetic calorimeter: status and performance improvements

Abstract

The electromagnetic calorimeter at the BaBar detector, part of the asymmetric B factory at SLAC, measures photons in the energy range from 20 MeV to 8 GeV with high resolution. The current status of the calorimeter, now in its seventh year of operation, is being presented, as well as details on improvements made to the analysis code during the last years.
