OsC Feedback and actionsFeedback to the Collaboration1.1 The 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.

1.4 The 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.

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


7

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 !

Top level deliverables

1.5 The 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


9

Top-level deliverables: TrackerAs 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

10

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


11

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

Oxford ATLAS Upgrade week: Summary 12

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 5x1034

• Physics and performance studies• Progress with L1CALO • Work needed to understand L1MU simulation• Justification for pixel system in phase-I

1/4/11


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 16.6.3.3 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?

Other issues from OsC report1.7 The 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.

1.8 The 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.

1.9 In 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.

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

LHC and ATLAS schedulesLHC• 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


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?

1/4/11


19

Timetable for approval

• LoI Dec 2011– Cover Phase-I in detail and some Phase-II

information• Ph-I TDRs• Ph-II TDRs Dec 2014
