  The LHC is well covered in terms of beam loss instrumentation. Close to 4000 ionisation chambers are installed to measure global beam losses all around the LHC ring, and diamond detectors are placed at specific locations to measure bunch-by-bunch losses. Combining the information of these loss detectors with that from additional instrumentation, such as current transformers, allows for enhanced understanding and control of losses. This includes a fast and reliable beam lifetime calculation, the identification of the main origin of the loss (horizontal or vertical betatron motion or off-momentum), or a feedback to perform controlled off-momentum loss maps to validate the settings of the collimation system. This paper describes the diagnostic possibilities that open up when such measurements from several systems are combined.
This is proposed as an Invited presentation from CERN Beam Instrumentation Group.
