    • Or, why so little data so far

  • Where to next?

    • Or, when will more data come?

48 h

  • 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 !

To 2 MJ

Main challenge will be learning to operate safely with destructive beams

Approved steps to 2 MJ
