Title :
The impedance database computation and prediction of single bunch instabilities
Author_Institution :
ANL, Argonne
Abstract :
The impedance database is a standardized 3D computation of the wake potential generated by a high-intensity beam. The database concept is described and compared to analytical and model-based approaches. The talk will address the computational challenges introduced by tapers, collimators, and very short bunches. Finally, single-bunch instabilities are predicted through tracking and compared to measurements at the Advanced Photon Source and other accelerators.
