DESCRIPTION:Speakers: BRACCO\, Chiara (Ecole Polytechnique Federale Lausan
 ne (EPFL))\nThe LHC collimation system has been used for beam cleaning and
  passive machine protection this year for the first time. The hardware com
 missioning tests carried out in preparation for operations with beam are p
 resented. Setup procedure towards nominal injection settings is analyzed t
 ogether with reproducibility and total beam time spent for collimator setu
 p. Locations of beam losses are reviewed and reasons for the highest losse
 s investigated. The achieved cleaning efficiency is also discussed. Operat
 ional performance and stability of the system\, interlock thresholds and i
 nterlock statistics (number of false interlocks generated) are treated. So
 ftware procedures\, settings and threshold limits are analyzed\, also in v
 iew of machine protection. Finally\, plans for higher intensity operation 
 and improvements (both on a short and long term) are presented.\n\nhttp://
