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: 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

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: whatever needed, see from experience
frome next years• P8• Removal of EPC and DFBX from tunnel to
surface via long SC links rated of 0.1-1 GW d.c.

LIU – LHC Inj Upgrade (R. Garoby)LS2 (2018) and LS3 (2012-23)
• Linac4 (160 Mev H- vs. 50 MeV H of Linac2)Ready by mid 2014Connected 2015?Reliability, brilliance…
• PS Booster upgrade:from 1.4 GeV (800 Gev)to 2 GeV to reduce space ahrge at PS injectionIntensity gain : +65%Project launched;
• SPS reduction of impedencenew optics with low t (2615 GeV)new 200 MHz cavitiesreduction e-clouds by vaccum chamber coating (or scrubbing?)

New baseline to follow the new EU strategy for HEP! Goal: HL-LHC approved by 2013
CB of 17 Nov 2011 , message from President of Council, Prof. Spiro:PDR needed in preliminary form 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 fix choice earlier

Magnet design: very challanging but not impossible. 300 mm inter-beamMultiple 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 TeVHigher 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 2x1034 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.
