Our Organization
Operations and Performance
  • Total luminosity
  • 3.0 fb-1 delivered, 2.5 fb-1 to tape 2.2
    fb-1 to tape with silicon on
  • Dataset has doubled each of the last 4 years
  • Stable collection of data taking efficiency 85

Detector Status - Executive Summary
  • Calorimetry and Muon systems working well
  • Tracking chamber (COT)
  • Aging not a problem, will be ok through 2009
  • Silicon longevity
  • Expect silicon detector to last through 2009
  • Radiation not expected to be a problem

  • High Luminosity running
  • Trigger
  • Requires constant attention
  • Upgrades on tracking and calorimetry fronts
  • DAQ
  • Built more bandwidth
  • Physics
  • No significant effect up to 3e32

No showstopper foreseen through FY09
Tracking Chamber -status
  • We addressed an aging problem of the Central
    Outer Tracker drift chamber in 2004
  • Aging was found to be due to hydrocarbon growth
    on wires
  • Addition of O2 to gas in June 2004 restored gain
    to original 2002 levels
  • Possible new evidence of aging at the highest
  • Minimal, if at all
  • New gas purification system to clean
    re-circulated gas expected to be complete later
    this year
  • Increased Oxygen from 70 to 100ppm. Seems to
    have stopped this aging

Relative Gain of Inner SL /Store
CDF Silicon Detectors
ISL/L00 Portcards
Silicon Longevity - details
  • Bias voltage required to fully deplete Silicon
    sensors changes with irradiation decrease
    type inversion increase
  • If depletion voltage larger than maximum safe
    bias voltage
  • cannot fully deplete sensors ? efficiency loss
  • Recent bias scans show innermost SVX layer (most
    vulnerable) is nearing inversion

Silicon stable and expected to outlast 8 fb1
The Leak
  • Recently, flow in East ISL/L00 portcard
    circuit dropped from 1.7 lpm (nominal) to 0.0

Access to Investigate
Chiller Trip
Spontaneous Drop

Boroscope pictures
Port card cooling ring
Cooling Pipes
Established Task Force
  • Objectives
  • Determine a safe short term operating
  • Determine probable cause of leak and repair it
  • Studying other potential vulnerabilities in
  • Plan
  • Expect repair to be completed during summer
  • 9-week shutdown starting on August 6th

Physics Impact
  • Established task force to assess impact on
    physics while off
  • Prelim conclusions
  • Efficiency for adding silicon hits to COT tracks
    and impact parameter resolution both only
    moderately affected
  • Forward electron ID down by 5
  • B-tagging
  • Efficiency down by 10-15 per jet
  • Mis-tag rate also down by 15
  • Re-optimization would mitigate efficiency loss
  • Higgs
  • Total lepton acceptance falls by lt5
  • Events with 1 Btag falls by 7
  • Events with 2 Btags falls by 20

High Luminosity Running
Trigger _at_ High Luminosity
  • Experience with luminosity at 3e32
  • Bulk of triggers for Higgs are fully functional
    to at least 3e32
  • Identified a few triggers with unacceptable rates
  • XFT and Cal upgrades to help deal with these
  • Using dynamic prescaling to optimize physics
    and bandwidth
  • High rate triggers have large prescale at high
  • Prescales relaxed as bandwidth becomes available
    at low luminosity
  • Most of the time is spent at below 1.5e32

No serious issue but continuous watch is needed
Ex dealing with runaway triggers
  • High PT muons CMX
  • L1 XFT upgrade - completed in Fall06
  • Add COT stereo layers
  • Rate reduced x4-5 with
  • 2 loss of efficiency
  • June 2007
  • Expect another factor of 2-3
  • L2 XFT matching in Z with full stereo tracks
  • Tighten r-??match
  • 5 post docs and students

L1 XFT Upgrade Red before Blue after
Ex dealing with runaway triggers
Missing ET jets
  • Upgrade L2 cluster finder
  • Switch to Cone based jets like offline
  • Better resolution Missing ET calculation
  • Deploy additional Pulsar boards and new decision
  • Other algorithms possible
  • Install and commission in June 2007
  • 14 postdocs and students !

Processing the Data
  • Computing will always require attention
  • Dealing with continually larger data sets, faster
    acquisition of data, and evolving technology
  • Recent successes in offline processing include
  • Detector calibrations automated
  • Standard Ntuples now made in an automated fashion
  • Automated string of high-level modules to do
    jet-E-scale, ID and trigger efficiencies on
    leptons, b-tagging efficiency, data-to-MC scale
  • All MC production done off-site
  • Enhanced GRID computing capabilities
  • Everything needed to include new data in any
    physics analysis with a lag time of lt12 weeks
  • We are elaborating a 5-year plan in conjunction
    with CD
  • Detailed CDF staffing needs per operation, per
  • Continue streamlining ops
  • Transition to CD jobs that match their
    personnels skills
  • Analysis ready data available up to April 2007
    (2 fb-1).

Summary thus far
  • The Detector is working well
  • Our triggers are under control
  • Offline is processing the data in a timely
  • No Show Stoppers
  • Now we will discuss the people

streamlining automating recruiting
People - Executive Summary
  • People are migrating for the LHC and other
  • This is not a new phenomena, started a long time
  • Brought to the forefront by the Brock/Whitmore
    report in 2004
  • Has affected us in many ways and weve taken many
    measures to mitigate its effect
  • Conducted CDF surveyed in 2005 and recently in
    Feb 2007
  • Personnel available has steadily declined and it
    will continue
  • In response, we have stabilized operations and
    weve been able to streamline and automate many
    labor intensive tasks
  • Considerable effort retaining, recruiting and
    planning ahead
  • But very importantly
  • Luminosity increase has made a tremendous
  • Lots of physics to do
  • Many opportunities for people to make a mark
  • The collaboration age profile is gt young, yet
  • Try to keep senior people engaged at all levels
  • We have focused our physics program through Higgs
  • These efforts have paid off and our expectations
    for 2009 are positive

Staffing - Overview
  • A critical issue to our success
  • Spokes and management team spend considerable
    amount of time on this
  • Started a systematic approach
  • Staffing spreadsheets (gap analysis)
  • Detector and Offline Ops, will extend to physics
  • By task, person, as a function of quarter yr
  • Identify holes
  • Institutional spreadsheets
  • FTE per person (with names) per year
  • Institutional responsibilities
  • Done 2 yrs ago, redone in February 2007
  • Identify peoplepower
  • Will start staffing sessions to weave the two
    into a tool that can allow us to make sure we are
    fully staffed through FY09
  • Things look ok, but we need to do the work !

Gap analysis spreadsheets
For all systems find holes early, streamline
further and recruit

Recruitment Why we are Successful
Many avenues have kept people involved in CDF
  • Focused our Higgs effort
  • Trigger upgrade and challenges
  • Rapidly increasing datasets
  • Great opportunities to analyze data
  • LHC delays
  • Leadership positions at CDF
  • Opportunity to make real, high-visibility,
  • Seeding with senior people if possible
  • Perceptions about LHC
  • Long delay for thesis
  • A lot of competition - too large
  • Difficulty for people to get engaged and feel
  • Opportunities for students and postdocs
  • MANY postdocs and students joining (despite
    popular beliefs)
  • CDF postdocs very competitive in finding faculty
  • Data, data, data Our Physics is compelling

Obtaining Resources In and Outside the
  • New institutions
  • Slovakia joined CDF on March 2007
  • Universidad Iberoamericana, Mexico are new
  • Athens has a request to join last month
  • International Fellowships
  • Two last year
  • 1 senior scientist (Fotis Photos, ex-CDF now at
  • 1 postdoc (Miguel Mondragon, from Mexico)
  • Two this year
  • Applications in, under review
  • Temp positions
  • Through CDFs guest and visitor budget
  • Help convenors travel, teaching relief etc.
  • Bring people to the lab for term periods
  • Etc

Recent postdocs joining CDF lt1 yr
  • Examples most were students at CDF that stayed
    on CDF
  • Enrique Palencia Cantabria gt FNAL
  • Fabrizio Margaroli Bologna gt Purdue
  • Anadi Canepa Purdue gt Penn
  • Olga Norniella Barcelona gt UIUC
  • Craig Group Florida gt FNAL
  • Valentin Necula Florida gt Duke
  • Nathan Goldschmidt Wisconsin gt Florida
  • Alison Lister Geneva gt UC Davis
  • Jen Pursley Hopkins gt Wisconsin
  • Bo Jayatilaka Penn gt Duke
  • Shang-Yuu Tsai new from Academia Sinica, Taiwan
  • Hyun Su Lee new from Korea
  • And several more
  • Places currently hiring PD for CDF
  • Rochester, MIT, Paris, INFN Fellows, Chicago,
    Fermilab (2),

Established Higgs Discovery Group
  • Elevated the status of the Higgs subgroup to a
    Physics Group
  • Link intimately all the tools relevant to the
    groups work and focus
  • Much activity, and opportunity, with
    Higgs-related trigger and physics task-forces and
  • Many institutions have been adding new people to
    work on such a broad Higgs effort
  • Many young and talented people staying at CDF to
    do exactly this
  • Such a mission will help pull CDF together in the
    years ahead
  • both in spirit and operationally
  • It has energized the collaboration!

Created Higgs Trigger Task Force
  • To open the trigger maximally for Higgs

HTTF Report Executive Summary
  • Efficiency for all SM Higgs channels 82-96
  • Significant improvement to previously
  • Rate below 200 Hz at L300E30
  • So, CDF can still do physics other than Higgs also

Keeping Senior People
  • 6 major physics analysis groups
  • 2 convenors per group
  • Successfully recruited senior physicists to lead
    our physics
  • 9/12 are faculty level physicists, 3 senior
  • Some recruited rescued from going to LHC and
    other experiments
  • Higgs group
  • Matt Herndon (Wisconsin/CMS), Mark Kruse
  • Top group
  • Kirsten Tollefson (MSU/Atlas), Robin Erbacher
  • Exotics group
  • Chris Hays (Oxford/Atlas/ILC)
  • EWK group
  • Eva Halkiadakis (Rutgers/CMS), Erik James
  • B group
  • Manfred Paulini (CMU/CMS)
  • Also on the Operations groups
  • Co-Head Offline Group
  • Donatella Lucchesi (Padova/CMS)
  • Associate heads Offline Group

The Balance
  • We have enough people to run the experiment well
    and do the physics.
  • We have a sufficient number of postdocs and
  • We spend a lot of time matching up people with
    the proper skill sets to particular jobs.
  • This gets harder through attrition
  • We struggle to fill a few key positions more than
    we would like. We are in discussions with the lab
    on how they can help in a few key areas.
  • Our expectation is that we will sprint across the
    finish line

Publication of physics results
From data taking to publication
  • Q What is the typical time between data being
    taken and it making it into a public result ?
  • A There is no typical
  • There is a minimum time for each new data period
  • Need to process, calibrate, align, ntuplize,
    validate, run existing analysis, present bless
  • This is done in a few months
  • Usual deviations from minimum
  • Wait for several periods to get better stats/syst
    and then just add to existing analysis
  • Wait for more data BUT improve analysis
  • Wait for new Offline code releases w/
  • Striving for a final release
  • Wait for new students postdocs to take on an
  • Wait for other analyses/tools that affect this

All that said
  • Expect final Offline release by end of this year
  • Many new tools in it
  • New forward tracking, final simulation, etc.
  • Expect final automations done
  • Low and high-level calibrations
  • It will be easier and faster to add data to an
    existing analysis and just run it
  • In that case the lag will be lt minimum above
  • Still
  • We are in a rather creative stage and bringing
    innovations to an analysis/search is in our blood
  • We can always update on demand on a fast track
    if that is what we want to do

Random case
  • Higgs analyses in 2009 Summer Conferences
  • Assume 6 fb-1 of data delivered, 5 fb-1
  • Assumed rate 130 pb-1 / month
  • At Best
  • Close datasets N months before conferences to
    allow for processing etc.
  • Data in analyses 5-N(130) 4.6 fb-1 (for
  • Another 1.5 fb-1 for 2010

A Look Ahead -- Exciting Prospects
  • W mass to 25 MeV, Top mass to 1 GeV?
  • Resonances in ee. mumu, tt, bb - TeV reach
  • SUSY reach to several hundred GeV
  • Higgs -- find it!
  • 3rd generation sector physics tau, B, Top
  • Di-bosons, single-top
  • Holistic test of SM through signature based
  • Compositeness

The core program keeps getting better with data!
By the way, our first 2 fb-1 result
Is a discovery !
  • CDFs perspectives for staffing through FY09 are
    very good
  • Enough people are committed to run CDF well
  • Work goes into finding good matches to where
    holes are
  • The detectors will work well through FY09
  • High luminosity is not an issue
  • Trigger is keeping up
  • Physics quantities dont deteriorate
  • Analysis and publications
  • Analyses are always improving
  • Can publish quickly if needed
  • Physics program has been extremely successful
    with 1 fb-1
  • Looking forward to extract all we can from as
    much data as we get
  • And if Nature is kind, to discover something else

We are ready to run through 2009
Impact while off
  • The absence of ISL and L00 impacts
  • COT-Silicon linking
  • Impact parameter resolutions
  • B-tagging
  • Forward lepton ID
  • To quantify impact
  • Re-track recent data dropping all ISL and L00
  • Produce Higgs MC removing ISL and L00 from
  • These overestimate the effects
  • Were taking data with the west half of ISL and
  • We did not re-optimized algorithms to account for
    missing pieces
  • Next we discuss impact from low level objects to
    high level physics

Tracking Impact
Z gt dileptons
  • Efficiency for adding silicon hits to COT tracks
    and impact parameter resolution both moderately

Algorithm Impact
  • B-tagging
  • Efficiency down by 10-15 per jet
  • Mis-tag rate also down by 15
  • Re-optimization would mitigate efficiency loss
  • Forward electron ID down by 5

Physics Impact
  • Evaluated change in total acceptanceefficiency
    after full selection criteria in several channels
    using MC
  • MH120 GeV WH(l?bb), ZH(llbb), ZH(??bb)
  • MH160 GeV H(WW)
  • Relative losses consistent across all channels
    and with data-based studies of previous pages
  • Total lepton acceptance falls by lt5
  • Events with 1 Btag falls by 7
  • Events with 2 Btags falls by 20
  • Worst case scenario Assuming no re-optimization,
    actual losses would be half this for that
    fraction of the data set taken with the east half
    of ISL/L00 off.

Details of Computing
  • Resources
  • 1 THz CPU _at_ Fermilab for data processing (FARM)
  • 8 THz CPU _at_ Fermilab for user analysis and Monte
    Carlo generation
  • 2.5 THz CPU off-site for Monte Carlo generation
  • Also exploits GRID
  • FARM can process 26M events per day
  • We log 4-5 M events per day
  • CDF uses a one pass data processing scheme
  • Data processed every 6-8 weeks
  • Use final calibration, alignment, reconstruction
  • Publication ready data available up to April 2007
    (2 fb-1)
  • Data validation and analysis ntuples follow FARMs
    by 4-6 weeks

Streamlining Shift Operations
  • Reduced shift crew by one member without
    sacrificing data-taking efficiency or safety of
    detector - December06
  • Automated tasks to allow shift crew to focus on
    decision making
  • Redistributed tasks to other shift crew members
  • Students and postdocs freed from shift duties
    available elsewhere in detector operations, e.g.
    in the silicon group
  • Improving detector safety and data-taking
  • New tool for monitoring beam
    conditions automatically
    detector HV in a safe state if beam
    conditions are unsafe
  • Automatic recovery of silicon
    HV crate
    problems is faster and keeps

    shift crew in control room

Streamlining Shift Operations
  • Shifts for data quality monitoring for all
    detector subsystems can be done from remote site
    - September 06
  • All monitoring plots available via Web
  • Established CO shift room in Pisa
  • Monitoring workstations and video conferencing to
    CDF control room
  • Physicists in Pisa currently covering owl shift
    one week a month
  • Reduce travel burden
  • Keep people engaged
  • Expect other European collaborators to take

    advantage of this
  • Extending to site in Japan
