Abstract

To make precision measurements with a CsI(Tl) calorimeter in a high luminosity environment requires that the crystals are well calibrated and continually monitored for radiation damage. This should not effect the total integrated luminosity which is particularly important for the \babar calorimeter to enable it to make CP violation measurements in the $B$ meson system. To achieve this goal a fibre-optic light pulser system was designed using xenon flash lamps as the light source. A novel light distribution method was developed using an array of graded index microlenses. Some initial results from performance studies are presented.
