Overview:
During Run 1, beam-induced quenches have not yet been a limiting factor in the operation the LHC. After the long shutdown, the LHC will operate with much smaller operational margins, and at two thirds higher beam energy. Losses downstream of collimation, debris from the interaction regions, and, last not least, the occurrence of dust particles crossing the beams in arbitrary locations around the ring (colloquially called U.F.O.s, unidentified falling objects), will make beam-induced quenches a much more likely scenario during Run 2.
In view of this, controlled beam-loss experiments have been carried out before the long shutdown, in order to gather data that allows extrapolating to operation at 6.5 TeV. Detailed analysis of the events has been carried out throughout the long shut down. It has revealed strengths and weaknesses in our understanding of beam-loss events and beam-induced quenches. Based on this experience, we have launched the effort to update the settings of beam-loss monitors around the ring.
It is the aim of this workshop to survey the operational experience of superconducting accelerators and transfer lines, analyze the results and lessons learned of beam-loss experiments at the LHC, scrutinize the status of numerical models for the prediction of quench levels in superconducting accelerator magnets, and review the strategies for beam-loss monitoring in the LHC after the long shutdown. Moreover, we intend to stimulate a discussion on road-maps for the experimental validation of numerical and analytical models for quench- and damage levels for transient beam losses in accelerator magnets.
