Report @ CERNKEK about LHC upgrades programs Lucio Rossi 14 December 2011
The path and goals: 3000 fb-1 – Lpeak< 5 1034 Rad. damage LRossi@CERN-KEK Dec 2011 2
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 LRossi@CERN-KEK Dec 2011 3
Cycle in the HL-LHC run 20 E+34 pile up heat deposition in IR and DS other? LRossi@CERN-KEK Dec 2011 4

Other changes • Cryogenics • During LS 2, a new refrigerator will be installed at P 4, to feed RF cavities and restore IR 5 L • Refrigerator 6. 5 k. W @ 4. 5 K: • 4. 5 k. W + 0. 25 k. W (flash) + 0. 12 k. W (thermal losses line & valve box) + 1. 6 k. W (contingency 33%) • During LS 3 new refrigerators for P 1 -P 5 • 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 Dec 2011 7
Other changes (list not exhaustive…) • R 2 E: whatever needed, see from experience frome next years • P 8 • Removal of EPC and DFBX from tunnel to surface via long SC links rated of 0. 1 -1 GW d. c. LRossi@CERN-KEK Dec 2011 8

Reliability, brilliance… • PS Booster upgrade: from 1. 4 Ge. V (800 Gev) to 2 Ge. V to reduce space ahrge at PS injection Intensity gain : +65% Project launched; • SPS reduction of impedence new optics with low t (26 15 Ge. V) new 200 MHz cavities reduction e-clouds by vaccum chamber coating (or scrubbing? ) LRossi@CERN-KEK Dec 2011 9

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 LRossi@CERN-KEK Dec 2011 15
Malta Workshop 14 -16 October 2010 HE-LHC @ 33 Te. V c. o. m 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 2 X 20 T to open the way to 16. 5 T/beam. Otherwise limit field to 15. 5 T for 2 x 13 Te. V Higher INJ energy is desirable (2 x. SPS) 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 2 x 1034 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.
