Title: Radiological Consequences of Beam Loss on Beamline Front End Collimator during Top-off Injection into the Storage Ring

Abstract

The primary radiological safety concern for the top-off injection, with the beam line front end safety shutters open, is the scenario where electrons could be conveyed down to the beam line through the front end due to the erroneous combination of lattice magnetic field settings and beam energy. It is of paramount importance to ensure that such events are of remote possibility. Particle tracking simulations by the NSLS-II Accelerator Physicists have shown that by a set of interlocking requirements of the lattice magnetic fields and by the implementation of physical apertures, the errant electron beam can be confined to the front end components within the storage ring.
