摘要：
3D simulation studies of the transverse impedance budget for long bunches in the FAIR synchrotrons have been started. Important transverse instability driving sources are the thin resistive wall and the kicker impedances. The major concerns are the required low momentum spreads and the additional loss of Landau damping due to the transverse space charge tune shift. The simulation code PATRIC has been extended in order to predict coherent instability thresholds with space charge and for broadband impedance sources. Simulation scans were performed to analyze the improvement of transverse stability in long bunches relative to a coasting beam.
