Abstract:
The BABAR experiment at the PEP-II e+e- collider at SLAC in California started taking data in May 1999. The aim of the experiment is to study CP violation in the B meson system. A central part of the BABAR detector is CsI(TI) electromagnetic calorimeter. To make precision measurements with a calorimeter in a high luminosity environment requires that the crystals are well calibrated and continually monitored for radiation damage. However, this should not impact the total integrated luminosity. To achieve this goal a fibre-optic light pulser system was designed. The light sources chosen were Xenon flash lamps. A novel light distribution method was developed using an array of graded index microlenses. Initial results from performance studies are presented.
