Abstract

Results from the 2008 and 2009 operation of the LHC BLM system are presented with respect to the dependability (reliability, availability and safety) of the system. Known limitations and measures taken are discussed. The accuracy of the beam abort thresholds with respect to the magnet quench levels are examined. Threshold levels at different energies are compared to the noise levels and the limits of the readout electronics. An extrapolation from the measured loss profiles (injection losses as well as betatron cleaning and momentum cleaning losses) toward the expected loss profiles at higher intensity is given. It is verified whether they are expected to stay below quench and damage levels (respectively the currently enforced abort thresholds).
