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

2. The path and goals: 3000 fb -1 – L peak < 5 10 34 LRossi@CERN-KEK Dec20112 Rad. damage

3. Tuning of the goal after summer 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: t run = t lev +t dec +t turn. The turnaround time after a beam dump is taken as 5 hours, t decay is 3 h while t lev depends on the total beam current LRossi@CERN-KEK Dec20113

16. Malta Workshop14-16 October 2010 HE-LHC @ 33 TeV c.o.m LRossi@CERN-KEK Dec201116 Magnet design: very challanging but not impossible. 300 mm inter-beam Multiple powering in the same magnet (and more sectioning for energy) Work for 4 years to assess HTS for 2X20T to open the way to 16.5 T/beam. Otherwise limit field to 15.5 T for 2x13 TeV Higher INJ energy is desirable (2xSPS) The synchrotron light is not a stopper by operating the beam screen at 60 K. The beam stability looks « easier » than LHC thanks to dumping time. Collimation is possibly not more difficult than HL-LHC. Reaching 2x10 34 appears reasonable. The big challenge, after main magnet technology, is beam handling for INJ & beam dump: new kicker technology is needed since we cannot make twice more room for LHC kickers.
