This note reports the analysis of the mis-steered electron in the NSLS-II storage ring for the determination of supplementary shielding. The potential angles and offsets of the mis-steered beam are calculated by implementing the cascaded parameter scan (CPS) along the beam-line. This method is originally developed for the top-off safety analysis, and has been well documented in ref. The basic idea of CPS is to combine the phase space images due to different magnet set-points into one superset, then re-populate virtual particles on a fine grid as the input of the downstream magnet scanning. The purpose of re-population in phase space is to avoid the redundant particle tracking calculation due to the multi-layer overlap of different magnet settings. A parallel python code of implementing the tracking study has been written, and benchmarked with other top-off safety simulators developed in SLAC and LBNL.
