Projects Pixel flex hybrid production complete; pixel detector installed ATLAS GRID testbed (PS, HS) Tier 2 Center Physics analysis Pixel detector commissioning (GB, MS, DJ, MRML are resident at CERN) Pixel monitoring Muon isolation studies Pixel optical link upgrade (OU, OSU, Ohio State)


Pixel Module: see Episode II

Schematic Cross Section(through here)

Bumps

Flex Hybrid (green)

Sensor

Wirebonds

ASICs

Pigtail (beyond)

OU responsible for design, fabrication, assembly, and testing of Flex Hybrids (FH). FH Construction completed May, 2005


Pixel Detector Commissioning

Electronics Engineer Rusty Boyd is resident at CERN to help in pixel and ID commissioning.

Contributions of OUHEP members at CERN: HVPP4 design, construction, installation (all) Off-detector electronics installation (complete) Pixel detector calibration (MS) ID shifts: Pixel & ID Data Quality, Pixel DAC, Cosmic Ray

and collision data taking, etc. (all) Laser Safety Officer (GB) Shift Leader in Matters of Safety (GB) Counting room M&O (all) ID cooling system operation (GB)


ATLAS Upgrade OU and OSU joined collaboration to develop the inner

detector optical link for the ATLAS upgrade LHC Luminosity will increase by factor of 10 in 2 phases Phase 2 upgrade installation in ~2017? Three year R&D phase (completed)

Collaboration with Ohio State U. Irradiations at CERN in Aug. 2006, 2007, 2008, 2009 & IU in 2008 Total OU budget $63K

OU and OSU are collaborating on Opto-box for the Insertable B Layer (IBL) Opto-box holds, powers, and cools opto-boards used for optical

fiber data transmission from IBL G. Boyd is technical contact OSU graduate student will work on project


Software Projects Tier 2 Center

ATLAS management selected OU, LU, UT-Arlington, UNM, as a Tier 2 Center (Southwest Tier 2 Center)

Collaboration developed grid software: PanDA OCHEP linux cluster deployed and running DOE EPSCoR funding for OU/LU NSF funding (subcontract from UTA)

Amount negotiated each year ($110K for FY10)

Physics Analysis: OCHEP collaboration begins on physics topics, building on Tevatron experience b tagging top physics Higgs/SUSY searches

US ATLAS Forum co-convenors: Top Physics: P. Skubic (OU) QCD: B. Abbott b-tagging: F. Rizatdinova (OSU)

Physics at the LHC will be driven by…


Hardware – pixel tracking system Software – alignment of the pixel tracking system; Physics object identification – b-jet identification

Heavily relies on the pixel tracking system; Development of the calibration of the b-tagging and mis-tagging

rates in situ e/γ tagging

Physics experience from the Tevatron Top quark physics Higgs boson searches SUSY searches

OCHEP contributions to ATLAS notes

Contributed to CSC note on flavor tagging performance

Contributed to muon-isolation note Authored INT note on b-tagging fake rates Authored INT note on ttbar cross section

measurement (approved) Co-authored INT note on SO(10) SUSY search



Conclusions

OCHEP personnel are contributing to ATLAS pixel detector commissioning and operation

OCHEP collaboration on ATLAS upgrade and IBL optical link development started

ATLAS SW Tier 2 Center created and OCHEP linuxcluster is deployed and is currently being upgraded to allow analysis jobs in addition to production jobs

OUHEP desktop cluster is deployed as Tier 3 resource and will be upgraded with ARRA funds
