18. Physics 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 !
