Abstract :
Lifetime measurements are reported for different operating conditions of the BESSY I storage ring. These experiments have been performed in an attempt to identify the relative contributions of different lifetime limiting processes as a basis for lifetime optimization. Broadening of the beam using white noise excitation has proved to be a helpful tool to obtain quantitative information on the relative strength of the contributions due to gas scattering and the Touschek effect.<>
