High Luminosity LHC (HL-LHC) historyTask force chaired by Francesco Ruggiero in 2001

Radiation damage limit ~700 fb-1

CERN task force on LHC machine upgrade -> LHC PR 626+666Luminosity: Lnom=1034 -> 1035, Energy: Ecm=14 TeV -> 25 TeV

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&Dand component development, prototyping, and final production.

SC magnet R&D for lumi upgrade also useful for energy upgrade: can beintegrated with LHC magnet consolidation. Beam dynamics R&D for LHCcommissioning also useful for LHC upgrade: needed to guide new IR design.

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 newtwork on accelerator physics & magnets design • NED Joint Research Activity : development of HF Nb3Sn SC

• 2007: following Lisbona EU strategy for HEP, White Paper: the split into Phase I and II• Phase I : 21034 peak with 120mm-120 T/m MQX for 2013• Phase II: 101034 peak ? with Nb3Sn MQX for 2020?

High Luminosity LHC (HL-LHC) historyLHC commissioning & first operation period

• Chamonix 2010: Phase for 2016-17 ? Longer than expected shutdown. 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 year run 250 fb-1/yPeak lumi 51034 cm-2s-1 levelling

• Start thinking to HE-LHC• WG chaired by Steve Meyer, started March 2010• Workshop Malta, October 2010

Cycle in the HL-LHC run20E+34 pile up

heat deposition in IR and DSother?

Levelling

150 days of Physics /y of this cyclewith 60% efficiency will give 250 fb-1

Which set of parameters we need to reach this goal?

LRossi-16Nov2011 9

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

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

Same technology,

strong synergy

• 750 MCHF new evalution M• 1000 FTE-y P• P+M 1000 MCHF (CtC !!!)• For convenience each system

regroup activities under FP7 HiLumi and outside it

• The StCom (Steering Committe, were all WP/System leaders are represented) will alternate meetings restricted to HiLUmi and extended to whole HL.

• We will not distinguish between FP7 beneficiaries (EU+KEK) and US labs except when necessary

Budget under construction

LRossi-16Nov2011 19

HiLumi is the focal point of 20 years of converging International collaboration• The collaboration wiht US and JP

on LHC upgrade started during the construction of LHC

• EU programs have been instrumental in federating all EU efforts

•With Hi-Lumi the coordination makes a step further: from coordinated R&D to a common project

• CERN is not anymore the unique owner, rather is the motor and cathalizer of a wider effort.

• Managed like a large detector collaboration (with CERN in special position as operator of LHC)

This program and budget to do what?

CB of 17 Nov 2011 (yesterday!), message from President of Council, Prof. Spiro:PDR neede 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)

LRossi-16Nov2011 23

Is it so difficult? Beam related issues…• Beam of > 1 A @ 7TeV (700

Mjoules!!)

• Most probably need of 25 ns (e-clouds and less brightness form Inj): qaultiy of collision vs quantity

• Very challanging AP issues…

• Needs of novel optics schemes (S. Fartouk)b 15 cm or lower

LRossi-16Nov2011 24

Is it so difficult? Magnet technology jump• LHC is already very pushed• 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 only way to be on the path toward HE-LHC (15-20 T

in 40 mm)

LQ , 4 m, 90mm: 11 THQ, 1 m, 120mm: 13T

LRossi-16Nov2011 25

Is it so difficult? Crab Cavity, for p-beam transverse manipulation at fs level!
