Description
Top-up operation at the Diamond-II storage ring will involve injecting bunches of electrons into the ring whilst the photon beamlines are in use. It is important, for the safety of the users, that electrons from the newly injected bunches cannot travel down the photon beampipe to the front end. For each beamline, all possible trajectories through the ID straight were identified and tracked through the machine to determine if any combinations of magnet settings exist that would simultaneously allow for stored beam and for electrons to be extracted through the front end. The full range of strengths for all the magnets/kickers were considered to account for any magnet power supply failures or different operating modes. Here we present the method used to track the electrons, summarise the results for the beamlines simulated so far and describe the interlocks required to ensure safe operation.
