  1. Report @ CERN-KEK about LHC upgrades programs Lucio Rossi 14 December 2011

  2. The pathand goals: 3000 fb-1 – Lpeak< 5 1034 Rad.damage LRossi@CERN-KEK Dec2011

  3. Tuning of the goal aftersummer Efficiency is defined as the ratio between the annual luminosity target of 250 fb-1 over the potential luminosity that can be reached with an ideal cycle run time with no stop for 150 days: trun= tlev+tdec+tturn. The turnaround time after a beam dump is taken as 5 hours, tdecay is 3 h while tlev depends on the total beam current LRossi@CERN-KEK Dec2011

  4. Cycle in the HL-LHC run 20E+34 pile up heatdeposition in IR and DS other? Levelling LRossi@CERN-KEK Dec2011

  5. Possible evolutiontoward 3000 fb-1 LRossi@CERN-KEK Dec2011

  6. IR Magnets(triplet, D1, D2, MQ4, …) SC CrabCavities, IR Collimation LRossi@CERN-KEK Dec2011

  7. Other changes Cryogenics During LS2, a new refrigerator will be installed at P4, to feed RF cavities and restore IR 5L Refrigerator 6.5 kW @ 4.5 K: 4.5 kW + 0.25 kW (flash) + 0.12 kW (thermal losses line & valve box) + 1.6 kW (contingency 33%) During LS3 new refrigerators for P1-P5 Warm compressor installed in surface. Warm gas lines in Pit Cold boxes installed in underground and surface (if 2 K or 1.8 K options) Distribution and transfer lines to equipments (magnets, DFBs, crab-cavities ?, SCL ?, sector powering ?...) LRossi@CERN-KEK Dec2011

  8. Other changes (list not exhaustive…) R2E: whateverneeded, seefromexperience frome nextyears P8 Removal of EPC and DFBX from tunnel to surface via long SC links rated of 0.1-1 GW d.c. LRossi@CERN-KEK Dec2011

  15. New baseline to follow the new EU strategy for HEP! Goal: HL-LHC approved by 2013 CB of 17 Nov 2011 , message fromPresident of Council, Prof. Spiro: PDR neededin preliminaryform by Oct 2012, endorsed by SAC and MAC, approved by CERN Mngt for Council and HEP strategy Group (final step : Council Bruxelles June 2013) Need to fixchoiceearlier LRossi@CERN-KEK Dec2011

  16. Malta Workshop14-16 October 2010HE-LHC @ 33 TeVc.o.m Magnet design: verychallanging but not impossible. 300 mm inter-beam Multiple powering in the samemagnet (and more sectioning for energy) Work for 4 years to assess HTS for 2X20T to open the way to 16.5 T/beam . Otherwiselimitfield to 15.5 T for 2x13 TeV Higher INJ energyisdesirable (2xSPS) The synchrotron light is not a stopper by operating the beamscreenat 60 K. The beamstability looks « easier » than LHC thanks to dumping time. Collimation ispossibly not more difficultthan HL-LHC. Reaching 2x1034appearsreasonable. The big challenge, after main magnettechnology, isbeamhandling for INJ & beam dump: new kickertechnologyisneededsincewecannotmaketwice more room for LHC kickers. LRossi@CERN-KEK Dec2011
