  1. Lucio Rossi The High LuminosityLHC Project DistinguishedLecturer 2013

  2. Content • Energy and luminosty • PresentLHC and luminosityevolution • Reasons for the upgrade • Luminosity Upgrade: the main ingredients • FP7 HiLumi Design Study • Furtherevolution: the Energyupgrade • HL-LHC main technologies

  3. High Energy Frontier New phenomena (new particles) created when the “usable” energy > mc2 [×2] High Precision Frontier Known phenomena studied with high precision may show inconsistencies with theory The twoDiscoveryFrontiers 2 routes to new knowledge about the fundamental structure of the matter

  4. LHC and Hadron colliders • Hadron colliders are the typicaltooling for High EnergyFrontiersbecause the total energyissolarge: 8 TeV (and later 14 TeV) • However all quarks and gluons inside the protons cancollideeachother the energy per collision issubdivided : 8 TeV/N • So there are manyevents and many traces in a p-p collision

  5. The interestingvery rare events • Interestingevents are like a needle in a haystack: very rare. • A Higgshappens 1 each 1012events!

  6. Luminosityis to collision rate • Afterenergy, Lumiis the mostimportnatparameters of a collider. Beamcurrent energy Beam size Beamcurrent and emittance: involveInjchain and whole ring βinvolve «only» 2 IRs, 600 m (but ATS…) LHC has been designed for L0All systems have singularlydesignedtentatively for ultimate 2L0 (almost…)

  7. IntegratedLuminosity in LHC (fb-1) In 2011: at 7 TeVaccumulated 5.6 fb-1

  8. CERN long term plan (tenyears)

  9. Possible evolution of luminosity Full upgrade Shut down to fixinterconnects and overcomeenergy limitation (LHC incident of Sept 2008) and R2E Shut down to overcomebeamintensity limitation (Injectors, collimation and more…)

  10. Magnets: 11 T dipoles, 12-13 QuadsCrabCavities : femtosecondaccuracySC links: 150-200 kA, 5 kV, 300-700 longNew cryogenic plants and otherequipment

  11. Changing > 1.2 km of LHC… Works all around the ring LHCb and Alice not considered for the moment

  12. Some of the hardware to change…

  13. Extending the lifetime of LHC by 10-12 years…

  14. Budget FP7 HiLumi LHC (EU funded Design Study) and the wholeproject HL-LHC Perfect score 15/15, ALL request to EU granted Estimatedcost for the thewhole HL-LHC over 10 years in M€ (October 2010) No infrastructure (100 MCHF)

  15. List of WP coordinators

  16. And then? HiLumi isdalso a prepration for anotherlargerproject: HE-LHC

  17. Possible timeline for an HE-LHC

  18. FP7-EuCARD2 program approvedstart May 2012. WP10-Future Magnets • Develop 10 kA class HTS acceleratorcables • Test in in a 5 T acceleratorqualitydipole • The aimis one day go into 16-10 T region

  19. HE-LHC in LHC tunnel or in 80 km new tunnel LHC tunnel: 16-20 tesla can by 26-33 TeV c.om. In the 80 km tunnel:For TLEP, then for a superHE-LHC Optimitationcouldbeat 16 T fieldlevel: collision energy 80 TeVc.o.m. Or 100 TeV for 20 T dipoles Much better new infrastructure. Howevermanycosts go linearly, or more, withlength. Magnetstoredenergy, beamenergyalso a concern Whatever solution, only a vigorousMagnet R&D (and on otherequipment )willenable to go beyond LHC energy

  20. HL-LHC Main Technologies • Superconductivitytechnlogies • Precisionand cryogenicmechanics • Large equipments and tooling • Ovens for 5-10 m 900 C high accuracy in vacuum • Power electronics • Cryogenic plants and cryo-equipment • New materialdevelopment for insulator rad-hard • Advanced «robotics» (or telemanipulation) • High vacuum • Infrastructure: • Civil engineering (Sc links) • Electrical engineering • Cooling and Ventilation and basic infrastructure

  21. What’snext? • December 2012:Industryinformation day (with TIARA/EuCARD): THIS workshop • June 2013: HL-LHC Project approvalby CERN Council(based on EU HEP strategy update of 2013) • July 2013:Catalogof items underpurchase • December 2013: Set up a forum ITLO to try to get the maximum support formIndustry: • to communicate and to findpartner for new development and then construction • Maximize the Industrial return: a goal of the projectisalso to increment the EU Industrycapability • 2015: Full funding of project, about 750 MCHF including design and prototyping. Secure about 200 MCHF of external collaboration (USA and Japan) • 2016-2020: construction and test • 2021:ready for installation
