Computer Simulation Studies of Single Beam Stability

Single beam stability in large e+e- storage rings has been studied by computer simulation techniques. The inputs to the study are single particle equations of motion (including wakefield effects) and longitudinal and transverse wakefields. These wakefields are obtained by numerical integration of Maxwell´s equations in the time domain. Qualitative and quantitative comparisons are made between the results of the simulation and data from PEP and PETRA, and the agreement is reasonable. Since the only numerical data needed for the simulation are lattice parameters and RF structure dimensions, it is now possible to predict beam stability in future accelerators.
