  1. LHC Performance Projection Thanks to Mike Lamont and Lucio Rossi Oliver Brüning BE-ABP CERN 1 HL-LHC WP2 Task Leader Meeting, 11thJune 2013

  2. HL-LHC WP2 Task Leader Meeting, 11thJune 2013

  3. Assumptions: • 130 days/year in the year following a long shutdown • 160 days/year in nominal long year • 0.2 Hubnerfactor up to LS3 • 25 ns BCMS for run II  -  1.4e34 max. in 2015 • 25 ns ultimate intensity for run III

  4. Low emittance Beams from the PS • 50 and 25 ns options (BCMS Batch Compression, Merging and Splitting) • Tested at end of 2012 run (50ns case shown below) • Robustness and operability still to be proven Test 4th December – Emittance from CMS luminosity 2.5 micron Nominal 50 ns 1.5 micron BCMS

  5. Beam from injectors LS1 to LS2 BCMS = Batch Compression, Merging and Splitting Almost a factor 2 gain in Beam Brightness at the ‘cost’ of 10% less bunches! HeikoDamerau, Steve Hancock, Alan Findlay

  6. Post LS1 – LHC potential performance All numbers approximate • 6.5 TeV • 1.1 ns bunch length • 150 days proton physics, HF = 0.2 • 85 mb visible cross-section • * different operational model – caveat - unproven

  7. Performance from injectors 2012 N.B. the importance of 50 ns in the performance so far.This at the expense of high pile-up. (And they are in the process of re-inventing themselves again)

  8. LHC performance: summary 2012

  9. Availiability Alick Macpherson

  10. RLIUP : Review of the LHC and Injector Upgrade Performance Review the expected performance evolution based on the Run-I experience Comparedifferent upgrade implementations Update the shut down planning for the LHC, it’s injector complex and the experiments in view of the above and create ONE coherent plan (LINAC4, LIU activities, experiments, LHC etc)

  11. RLIUP : Review of the LHC and Injector Upgrade Performance • Operation of LHC as it is, with normal consolidation • Upgrade: • Addition of PIC : Performance Improving Consolidation ( 1000-1200 fb-1) • Addition of Upgrade Scenario 1 ( 2000 fb-1) • Addition of Upgrade Scenario 2 ( 3000 fb-1) The same scheme applies for LIU

  12. Review Program: • Session 1: Experiments experience and expectations Mike Lamont and Austin Ball • Session 2: Performance after LS1 and once Linac4 is connected to the PSB GianluigiArduini and Stephen Hancock • Session 3: PICs and Upgrade scenario 1 MalikaMeddahi and Lucio Rossi • Session 4: Upgrade scenario 2 Brennan Goddard and Roland Garoby • Session 5: Ion related upgrade plans Massimiliano Ferro-Luzzi and Oliver Brüning • Session 6: Summary and Conclusions

  13. Upgrade matrix (for discussion)
