Extending our approach recently described in * we present a new method to accurately calculate point-charge geometric wakefields from wake potentials due to a much longer bunch, typically obtained with a time-domain EM field solver. By allowing a long bunch in the EM solver, this method can significantly reduce the need for computer resources as well as drastically shorten the computing time. On top of that, the method provides profound physics insights. We give examples of longitudinal and transverse wakefield calculations for 2D and 3D accelerator structures which illustrate the effectiveness of the new method.

In this paper we report the upgrade of the diagnostics of the beam injection system at BNL NSLS. Installation of the commercially available turn-by-turn BPMs in the VUV and X-Ray rings allowed us to build detailed injection models for each of the rings and led to creating the operational tools for real time monitoring and improving of the beam injection into the rings.
