  • We can produce long fills but we did not manage to have a programmed dump yet
  • Beam lifetime is excellent (>100 h)
  • From LHC Physics Coordinator @ LMC (07/04/2010):
    • Accumulated order of 300 mb-1/expt
    • Several million inelastics on tape
    • Inelastic rates typically up to ~120 Hz when optimized and ~1.1e10 p/bch, small emittance
    • Luminosity life time seen well above 20h !
