ITS upgrade
Meeting Gruppi INFN

  V. Manzari – CERN, 6 Novembre 2012

Upgrades: status
On September 27 after the third round of discussions with ALICE, the
LHCC has endorsed our Upgrade LoI and ITS CDR. Minutes are not out
yet, but there is a statement which we can quote issued by the LHCC
chair:
“There is an interest amongst the collider experiments (ALICE, ATLAS and CMS)
for a continued heavy ion programme that gives access to rare final states. This
programme will extend well into the 20ies assuming the current HI running mode of
one month per year.
The physics programmes of the two general purpose detectors and ALICE are
complementary: while the former may focus on selected hard probes ALICE will be
optimized for particle identification at low transverse momenta. The experiments
are hence sensitive to different ”messenger“ signals and phases of the evolution of
the quark gluon plasma.
This increase in sensitivity for ALICE entails an upgrade of the rate capability of
the TPC, a high resolution ITS, and a major upgrade of the online system and the
read-out electronics.
The LHCC commends this joint approach to heavy ion physics and endorses the
upgrade plans of the ALICE collaboration. The committee is looking forward to the
seeing detailed technical solutions presented in the respective TDRs.. ”

Upgrades: next steps

RRB 29 Oct -1 Nov
o   Extension of the construction MoU
o   General Endorsement of the Upgrade
TDRs to be prepared in O(1 year)
o Will define the construction design
o Will contain the specific commitments of the Institutions to the
projects
o Followed by MoU addendum (or addenda)

R&D
o Will have to continue vigorously throughout the process, with
substantial funding, agreed within each project
Target date for ITS TDR August 2013 for submission to LHCC in
September 2013

Running scenario after the upgrades
• Pb–Pb
   •   int. luminosity per year 2.85 nb -1 (peak L = 7x1027 cm-2s-1)
   •   needed int. luminosity 10 nb -1, statistics 8x1010 events
   •   3.5 month of running
   •   +1 month of special run at low field for dileptons
• p–Pb
   • max event rate 200 kHz, flat (L = 1029 cm-2s-1)
   • needed int. luminosity 50 nb -1, statistics 1011 events
   • 0.5 month of dedicated p–Pb run
• pp
   • max event rate 200 kHz, flat (L = 3x1030 cm-2s-1)
   • needed int. luminosity 6 pb -1, statistics 4x1011 events
   • 2 month of dedicated pp run, assumed in 1 year
  The list above fulfills the ALICE physics program as presented in the LoI.
   A run with lower mass nuclei (e.g. Ar) could be considered in addition, if a
  physics case for it would emerge.

Upgrades: a possible running scheme

• ALICE plans to run 6 years with upgraded detector, i.e. until 2026
  (assuming start in 2019 and 2 years break of LS3)
• Possible scenario:
   • 2019 – Pb–Pb 2.85 nb-1
   • 2020 – Pb–Pb 2.85 nb-1 (low magnetic field)
   • 2021 – pp reference run

    • 2022 – LS3
    • 2023 – LS3
    • 2024 – Pb–Pb 2.85 nb-1
    • 2025 – ½ Pb–Pb 1.42 nb-1 + ½ p–Pb 50 nb-1
    • 2026 – Pb–Pb 2.85 nb-1
• This would not require pp running during high-luminosity runs, only a
  short time before a heavy-ion run for setting up and commissioning.

 Overall cost estimate for the major upgrade projects
       Detector components and production costs
       Upgrade items and Common Project

              -    ZDC included in “Trigger Detectors”, EMCal and HMPID require minor funds
              -    The Offline cost is the investment needed for the offline central services at CERN
