Outline Report from OsC Status of the budget Next OsC International context Project management issues – Use of working allowance Aims of this meeting 210/5/11 UK-ATLAS Upgrade Review meeting: May 2011

UK ATLAS Upgrade project 13 Universities STFC/RAL PPD STFC TD RAL/ATC Three year project – April 2010-March 2013 R&D for ATLAS Upgrade programme – Maintain UK leadership – Builds on heritage of current ATLAS development and construction and Tracker Upgrade project 310/5/11 UK-ATLAS Upgrade Review meeting: May 2011

Report from OsC Impressed with the work done Reporting procedures to be revised – Report by areas (  tracker + L1CALO, L1Trk, HLT, Computing?) Key issues raised for next meeting – Budget – Establish baseline – Other issues Impact: working with UK industry Understanding the interfaces in the tracker project Next OsC Friday 8 th July – Deadline for documents Friday 10 th June 10/5/11 UK-ATLAS Upgrade Review meeting: May

OsC Feedback and actions Feedback to the Collaboration 1.1The Committee congratulate the Collaboration on achieving as much as they had given the funding constraints and in light of the changes to the LHC schedule. They also congratulate the Collaboration on the UK roles in the international collaboration and express their support of the project. 1.4The Collaboration request an updated set of Finance Tables by the end of May 2011 showing a reconciliation of the project grant and RG funds within the overall funding enveloped approved. 10/5/115 UK-ATLAS Upgrade Review meeting: May 2011

Project issues Total budget to reconcile with PPAN award – Due to RGs not being cut – Project funding is 68% of proposal – Require saving of ~£1M UK-CB meeting to discuss how to achieve reduction – Identify savings via 15% reduction in RG NOTE: not a cut in RG posts, redeployment of effort within RGs Generally, effort moved into generic R&D and ATLAS M&O – Further savings from underspend in PPD and TD in FY 10/11 – Small savings from consumables and travel – (£70k deficit remains) 10/5/11 UK-ATLAS Upgrade Review meeting: May

Impact of RG reduction Revised budgets and FTEs received from groups FTE information circulated to WP leaders and Area managers to evaluate impact – To be discussed today – Will be required to justify programme with reduced effort to OsC Back of the envelope calculation – Approx 12FTEs lost across Universities in FY11/12- FY12/13 out of a total of 142FTE – Less than 10% cut in FTEs – So we should be ok, but ! 10/5/11 UK-ATLAS Upgrade Review meeting: May

Top level deliverables 1.5The Committee feel that the Collaboration need a clearly established baseline project management plan for the descoped R&D phase of the project. This recognises some of the uncertainties that still exist with future developments and the need for effective project management in what is a large and complex project. 10/5/11 UK-ATLAS Upgrade Review meeting: May

Top-level deliverables: Tracker As presented at last OsC meeting Strip tracker: – A full electrical 250nm tracker stave, – A full length 130nm thermo-mechanical stave, – A 130nm electrical short stave (stavelet) Pixels: – Tested IBL sensors, – Layout of pixel system for upgrade, – Delivery of 4-chip prototype modules for pixel upgrade 10/5/11 UK-ATLAS Upgrade Review meeting: May

Top-level deliverables: Trigger and computing L1Calo: – trigger performance studies for input to phase-I and phase-II trigger upgrade; – conceptual design of a topological processor; – technology evaluation for L1Calo hardware Track trigger: – performance studies – conceptual design of a track trigger HLT : – Upgrade and optimisation of the HLT tracking, – trigger selections and steering software. 10/5/11 UK-ATLAS Upgrade Review meeting: May

Top level deliverables: computing Computing: – Software for full simulation of events with pile-up; – improved use of memory in software; – Updated radiation level calculations Discuss today and confirm these as the baseline top-level deliverables and identify key milestones and schedule 10/5/11 UK-ATLAS Upgrade Review meeting: May

Physics & Simulation Simulation and software cuts across the upgrade both for Phase-I and Phase-II – Need to make case based on physics and performance to collaboration and funding agencies Technical issues: implementation of geometries in GeoModel Merging Utopia into mainstream releases (64bit identifiers) Validating pileup tools to go 5x10 34 Physics and performance studies Progress with L1CALO Work needed to understand L1MU simulation Justification for pixel system in phase-I 1/4/1112Oxford ATLAS Upgrade week: Summary

Simulation and Software Fast and full simulation tools – Fast tracking Fatras: basic layout studies with single-particles – Full simulation Geant4: more detailed analysis eg fakes and material issues Studies often show up issues that apply to current detector and software 64-bit release of deploying on GRID – Validate and then produce high luminosity samples Work can count for authorship – Many interesting tasks – Is there a list somewhere? – Encourage participation through OTP credit? 1/4/1113Oxford ATLAS Upgrade week: Summary

Other issues from OsC report 1.7The Committee ask the Collaboration to include their change control procedures within the project management plan, including changes in technology or to specification, so as to provide the Committee with a clear overview of how the Collaboration is recording and managing change. 1.8The Committee agree that the Collaboration should consider how the services side of upgrade will be managed. Although they are not directly responsible for this aspect of the project, they should be willing to influence this and impact on any possible solutions. The Committee request that a short report on this area be included in the next report. 1.9In their next report, the Collaboration is asked to outline their impact plans and agenda, including efforts to engage with UK industry, planned CASE studentships etc. 10/5/11 UK-ATLAS Upgrade Review meeting: May

Integration Services – Need to understand services from ID out of ATLAS – Type III and Type IV cables would be very difficult to replace (as would be SCT type II) → do re-use Limited number of new services possible in parallel (for optical fibres and cooling), but not for electrical cables. Is this compatible with powering (LV and HV) options discussed at the moment? Schedule implications if we decide to replace these cables – Need feedback to this assumption 1/4/1115Oxford ATLAS Upgrade week: Summary

LHC and ATLAS schedules LHC Phase-0 Shutdown: – End 2012-mid 2013 – Physics resumes 2014 Phase-I shutdown – End of 2017 – Physics resumes end of of 2018 Phase-II – End of 2021 ATLAS Phase-0 – IBL installation – Repairs/consolidation Phase-I shut down (being discussed) – Muon small wheels – Mini-FCAL – L1 calo topological trigger – Calorimeter readout – NewPix Phase-II – Tracker  ready on surface end of 2020 – TDAQ – Phase-I carry-over 10/5/11 UK-ATLAS Upgrade Review meeting: May

LHC issues Unless experiments make a clear statement for 25ns bunch-crossing, LHC will go to 50ns as it is less challenging option – But we should be prepared for 50ns as technology may drive this (x2 in tracks but leveling means still only about 200 pile-up events/crossing) When do we know? – More simulation Where are we with this? 1/4/1118Oxford ATLAS Upgrade week: Summary
