Agenda M. Calviani - R2E Review - Introduction Session 1
RadMons • RadMon calibration (J. Mekki – EN/STI) • How RadMon are calibrated • Accuracy/uncertainties • Calibration improvements • RadMon generalities and installation (G. Spiezia – EN/STI) • RadMon types and location in the LHC underground areas • Requirements and possible changes M. Calviani - R2E Review - Introduction Session 1
LHC– radiation and observation • Additional (R2E-related) weak points (M. Calviani – EN/STI) • P4 LSS/UX45 beam-gas levels • P6 UX65 beam-gas levels – monitoring results • DS/ARC and operation with 25ns bunch spacing • UX/UL junction weak-point • LHC operational perspectives (M. Lamont – BE/OP) • Main question for 2012 operation • 25ns scrubbing? • Target luminosities for 2012 and beyond • Vacuum evolution 2011/2012/LS1 (V. Baglin – TE/VSC) • Vacuum behaviour during 50 ns operation • Expected and measured pressure during 25 ns MDs in 2011 • Expected scrubbing periods during 2012 • Confirmation of pressure values in DS/ARC during operation • Beam-gas radiation levels in FLUKA (R.
