Description
During 2015, injections of 144 bunches into the LHC induced losses of up to 88% of the dump thresholds on the TDI. During run 2 these losses were studied in greater detail with diamond based particle detectors. It was found that the main loss contribution is due to ghost bunches, originating from the SPS, swept over the TDI during the rise and fall time of the injection kicker magnet MKI. This contribution will summarize the measurement results (transversal and longitudinal losses) in comparison to run 1. In addition, possible loss mitigations, already applied for a first time during an MD, will be discussed in view of injections of 288 bunches planned for operation in 2016.
