  1. The FP7 HiLumi LHC Design Study and HL-LHC project Lucio Rossi HL-LHC Project Coordinator – CERN FP7 HiLumi Public Meeting 18 November 2011

  2. Luminosity: educatedguess over 10 y Shut down to fixinterconnects and overcomeenergy limitation (LHC incident of Sept 2008) Shut down to overcomebeamintensity limitation (collimation, New Cryo P4,…) Inj. upgrade Hdwlimit? LRossi-16Nov2011

  3. The need for the upgrade LS3 LRossi-16Nov2011

  4. High Luminosity LHC (HL-LHC) historyTask force chaired by Francesco Ruggiero in 2001 Plot J. Strait Radiation damage limit ~700 fb-1 Plan luminosity upgrade by 2014. New low-b quads with high gradient and larger aperture based on Nb3Sn SC require 9-10 years for short model R&D and component development, prototyping, and final production. Slidefrom F. Ruggiero , 2004 CERN task force on LHC machine upgrade -> LHC PR 626+666 Luminosity: Lnom=1034 -> 1035, Energy: Ecm=14 TeV -> 25 TeV SC magnet R&D for lumi upgrade also useful for energy upgrade: can be integrated with LHC magnet consolidation. Beam dynamics R&D for LHC commissioning also useful for LHC upgrade: needed to guide new IR design. LRossi-16Nov2011

  5. High Luminosity LHC (HL-LHC) historyLHC construction period • Lhc Accelerator Research Programme, LARP • LARP has given fundamental contribution to the hardware development and to the conceptual study for High Lumi • FP6-CARE • HHH, a newtworkon acceleratorphysics& magnetsdesign • NED Joint ResearchActivity : development of HF Nb3Sn SC • 2007: followingLisbona EU strategy for HEP, White Paper: the split into Phase I and II • Phase I : 21034peakwith120mm-120 T/m MQX for 2013 • Phase II: 101034peak? withNb3Sn MQX for 2020? LRossi-16Nov2011

  6. High Luminosity LHC (HL-LHC) historyLHC commissioning & first operationperiod • Chamonix 2010: Phase for 2016-17 ? Longer thanexpectedshutdown. Limited performance, machine less flexible. • Decision of CERN Mngt, summer 2010 (formalized in Nov.2010) : • Regroup main upgrade for >2020: HL-LHC • 3000 fb-1 in 10-12 yearrun  250 fb-1/y • Peaklumi51034 cm-2s-1  levelling • Start thinking to HE-LHC • WG chaired by Steve Meyer, started March 2010 • Workshop Malta, October 2010 LRossi-16Nov2011

  7. LEP/LHC : the best use of the (renovated) existing infrastructure LHeC ? LRossi-16Nov2011

  8. Cycle in the HL-LHC run 20E+34 pile up heatdeposition in IR and DS other? 150 days of Physics /y of this cycle with 60% efficiencywillgive 250 fb-1 Levelling Which set of parameters weneed to reachthis goal? LRossi-16Nov2011

  9. 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-16Nov2011

  10. Our Final Goal: Given by Physics3000 fb-1 in 10-12 year of RUN LRossi-16Nov2011

  11. Many changes : IR Magnets(triplet, D1, D2, MQ4, …) SC CrabCavities, IR Col, New Cryo IP1-IP5, Cold Powering on surface 0.1-1 GW d.c. HTS LRossi-16Nov2011

  12. Opportunity, justwhen HL-LHC started • FP7 Design Study call: deadline 25 Nov 2010 • (experiencewith FP7-sLHC-PP, FP7-EuCARD) • Forming the consortium • 14 Institutes from the EU Research Area • 5from USA, 1 from JP • CalledFP7 HiLumi LHC Grant Agreement 284404 LRossi-16Nov2011

  13. Budget FP7 HiLumi and HL-LHC Perfect score 15/15, ALL request to EU granted Estimatedcost for the thewhole HL-LHC over 10 years in M€ (October 2010) LRossi-16Nov2011

  14. Status of the FP7 DS Grant Agreement signed by EC in October and now by all Beneficiaries First tranche of money (60% of the 4.9 M€) from EU has arrived to CERN, for redistribution Consortium Agreement sent to partner The US labswillpartecipate to FP7 HiLumi as associatepartner (underexisting agreement or with a new MoU LRossi-16Nov2011

  15. Staff for HiLumi LHC (EU FP7) LRossi-16Nov2011

  16. Staff HiLumiwith 377 p-m by US Labs 163 FTE-y LRossi-16Nov2011

  17. The HL composition DS collimation shifted in 2018 Cryo-col + 11 T Dip. isnow in baseline (but it must bedemonstrated SC links gets support fromvarious collaborations Matching section and correctors Collimation Project High Field Magnets R&D Beam Diagnostics HE-LHC Studies Study on HE-LHC getswider support EuCARD2 WP on HTS dipoles Hardware Commissioning LRossi-16Nov2011

  18. Budget under construction • 750 MCHF new evalution M • 1000 FTE-y P • P+M  1000 MCHF (CtC !!!) • For convenienceeachsystem regroupactivitiesunder FP7 HiLumi and outsideit • The StCom (SteeringCommitte, were all WP/System leaders are represented) willalternate meetings restricted to HiLUmi and extended to whole HL. • Wewill not distinguishbetween FP7 beneficiaries (EU+KEK) and US labsexceptwhennecessary FP7 HiLumi Sametechnology, strongsynergy LRossi-16Nov2011

  19. HiLumiis the focal point of 20 years of converging International collaboration • The collaboration wiht US and JP on LHC upgrade startedduring the construction of LHC • EU programs have been instrumental in federating all EU efforts • WithHi-Lumi the coordination makes a stepfurther: fromcoordinated R&D to a commonproject • CERN is not anymore the unique owner, ratheris the motor and cathalizer of a wider effort. • Managedlike a large detector collaboration (with CERN in special position as operator of LHC) LRossi-16Nov2011

  23. Is itsodifficult? Beamrelated issues… • Beam of > 1 A @ 7TeV (700 Mjoules!!) • Most probablyneed of 25 ns (e-clouds and lessbrightnessformInj): qaultiy of collision vs quantity • Verychallanging AP issues… • Needs of novelopticsschemes (S. Fartouk)  15 cm or lower LRossi-16Nov2011

  24. Is itsodifficult? Magnettechnologyjump • LHC isalreadyverypushed • Passing from 8 T (4 T today!) to 11 T in 2018 in LHC dipole • Passing to 12-13 T in IR Triplet: 140 mm!! • But is the onlyway to be on the pathtoward HE-LHC (15-20 T in 40 mm) LQ , 4 m, 90mm: 11 T HQ, 1 m,120mm: 13T LRossi-16Nov2011
