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..”

Target date for ITS TDR August 2013 for submission to LHCC in September 2013

Upgrades: next steps

• 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.

Running scenario after the upgrades

• 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.

Upgrades: a possible running scheme

ITS UpgradeBreakdown of the CORE Cost Estimate

V. Manzari - INFN Bari CSN III – 18 Settembre 2012

Option 1: 7 layers of monolithic pixel detectors, which would provide excellent standalone tracking efficiency and pt resolution, but limited PID capability.

Option 2:a combination of 3 innermost layers of hybrid pixel detectors and 4 outermost layers of strip detectors, which would provide better PID capability but worse standalone tracking efficiency and momentum resolution.
