US ATLAS Operations Program, SLAC 7/16/09 Tuts

  3. Some History • The US ATLAS construction project has been completed • $165M • US contributed to all major systems • Inner detector (SCT, Pixel, TRT) • Calorimeters (LAr, TileCal) • Muon system (MDTs, End Caps, CSC, Alignment) • Trigger and Data Acquisition (ROIB, HLT, DAQ) • Core software, Computing • About 20% contribution to overall ATLAS • As we moved to the operations phase, our responsibilities evolved from our hardware responsibilities US ATLAS Operations Program, SLAC 7/16/09 Tuts

  4. US ATLAS Operations Program • Host laboratory is Brookhaven National Lab • Three principal components: • WBS 2 - Software & Computing (S&C)) • Computing infrastructure: Tier 1, Tier 2 • Core software, computing support to facilitate physics • WBS 3 - Maintenance & Operations (M&O) • Pre-operations, commissioning, long term M&O • WBS 4 - Upgrade R&D • To handle future luminosity increases, prepare for upgrade construction project • [WBS = Work Breakdown Structure] • The Operations program supports technical personnel, equipment, shared computing US ATLAS Operations Program, SLAC 7/16/09 Tuts

  6. Funding Targets US ATLAS Operations Program, SLAC 7/16/09 Tuts

  7. What is not supported by the US ATLAS Operations Program? • For personnel the Ops program does not support physicists salaries (grad students, postdocs, scientists, faculty) • Our test is whether the person is on a “physics” career path • It does not support physicist travel or COLA while at CERN • It does not support local computing resources (“Tier 3”) • All of the above we judge to be the responsibility of the core (“base”) program US ATLAS Operations Program, SLAC 7/16/09 Tuts

  8. US ATLAS Institutions • ATLAS is an international collaboration • Individual institutes are voted in by the ATLAS Collaboration Board (CB) • Currently 44 US institutes (from 22 states) • Albany, ANL, Arizona, UT Arlington, Berkeley LBL and UC, Boston, Brandeis, BNL, Chicago, Columbia, UT Dallas, Duke, Fresno State#, Hampton, Harvard, Indiana, U Iowa#, Iowa State, UC Irvine, Louisiana Tech* , Louisville#, Massachusetts, MIT, Michigan, MSU, New Mexico, NIU^, NYU, Ohio State, Oklahoma, Oklahoma State, Oregon, Pennsylvania, Pittsburgh, UC Santa Cruz, SLAC, SMU, South Carolina*, SUNY Stony Brook, Tufts, Illinois Urbana, Washington, Wisconsin, Yale • Corresponding to 39 voting institutions • * = affiliated with BNL; # = affiliated with SLAC; ^= affiliated with ANL • As of Sept 30, 2008 (used to determine our “dues” to ATLAS) [7/15/09] • 38/169 voting institutions (22%) • 395/1817 “current M&O authors” = ~PhDs (22%) – for cat A/B (these are the shared operating costs for the detector) [428/1889 – 22.7%] • 592/2800 M&O authors + in process of qualifying + students (21%) [634/2893 – 21.9%] • 497.75/2347.25 Operations tasks share (students count .75) (21%) [551.75/2536.25 – 21.8%] US ATLAS Operations Program, SLAC 7/16/09 Tuts

  18. T1 & T2 Resources • US T1 and T2 facility anticipated pledges • From Feb 09 review – changing with LHC schedule US ATLAS Operations Program, SLAC 7/16/09 Tuts

  19. 4. Upgrade R&D • The Operations Program supports the R&D necessary needed for construction of an upgraded ATLAS • Phase 1 (~2014/15 install) envisions ~3x1034 and few hundred fb-1 • Inner B layer (IBL) silicon replacement • Muon and TDAQ • Phase 2 (2018/19??) luminosity goal of 1035 and enough integrated luminosity that inner detector requires full replacement, Calorimeters, Muon, TDAQ • Upgrade activities will be presented at this meeting by Abe Seiden and others US ATLAS Operations Program, SLAC 7/16/09 Tuts

  20. Analysis Support • While the Operations Program does not manage physics, it does provide support for analysis activities – under Jim Cochran (Iowa State) • US ATLAS goal is to support entry into overall ATLAS physics activities • 3 Analysis Support Centers: BNL, ANL, LBNL (and SLAC) • Host “Jamborees” on various analysis topics, tutorials • Analysis Support Group • Team of “virtual” experts that can answer your questions • Physics & Detector Performance Forums • A more informal venue in which to discuss analyses, issues, in US time zone • Venue for practice talks for US conferences US ATLAS Operations Program, SLAC 7/16/09 Tuts

  21. US ATLAS and DOE & NSF • US ATLAS Operations Program is jointly funded and managed by DOE & NSF • US LHC OP is reviewed annually by DOE/NSF with outside consultants • Joint Oversight Group (M. Procario (DOE) + M. Goldberg (NSF)) meet twice yearly • BNL Program Office handles budgets; we get input from Executive Committee on resource priorities • DOE funding distributed via BNL subcontracts & NSF funding distributed via Columbia subcontracts • Agencies seek advice from US ATLAS OP management on core program needs and priorities • DOE “help” funds (has been $600k-$850k) • We review core program needs individually with each of the 44 institutes in US ATLAS US ATLAS Operations Program, SLAC 7/16/09 Tuts

  22. US ATLAS and ATLAS • The US ATLAS Operations Program management interacts closely with overall ATLAS management • Coordinating resource priorities with overall ATLAS priorities • Serving as “National Contact Physicists” for the US • Supporting the “per capita” operating costs for overall ATLAS (called cat A and B costs, ~$10k/year/per PhD collaborator) • Advising and serving as a point of contact for ATLAS management regarding new US groups US ATLAS Operations Program, SLAC 7/16/09 Tuts

  23. US ATLAS - Conclusions • US activities on ATLAS in Computing & Software, Maintenance & Operations, Upgrade R&D are managed and funded (DOE &NSF) centrally through the US ATLAS Operations Program • Operations Program supports technical personnel & equipment • Operations Program pays for per capita costs for US PhD physicists • ATLAS is an international collaboration – after being accepted by ATLAS you are automatically in US ATLAS • New smaller institutions have typically joined affiliated through an existing US group until they prove themselves and build up group strength • We are anxiously awaiting first beam and the start of the physics program – we hope you will join us! • If you are considering joining ATLAS we can help to interface you to the overall ATLAS management • At this workshop you will hear more details of some of the ongoing activities US ATLAS Operations Program, SLAC 7/16/09 Tuts
