TED Runs

Complete list of runs with beam intensity and # bunches was collated by velo and can be found here.

Normal runs good for IT alignment

  • Tracks is with tuning that gives only TED tracks , low angle [+/- 20 mrad, originating from TED], less than 4k hits. Total 11662 tracks

  • All of these runs were reprocessed using Helge's configuration. The files are available either on castor /castor/cern.ch/user/m/mneedham/run50XXX-reprocessed4, or on lphe cluster /lhcb/data/data3/ted/run50XXX-reprocessed4. )Pedestal following off. For pedestal following on change the 4 to a 3)

  • See here for details and xml files for the databases

  • Data in denotes the best spill to use [or whether to merge spills]

  • Timing quality if run is well timed. Only good quality timing runs should be used for efficiency studies
