Action Items from July 2004 Review

• Understand Clearances for Layer Zero (in 2004
  Shutdown)
• Incorporate Physics Commissioning in Installation
  Plans and Schedule
• Review Manpower Estimates, articulate needs for
  extra-DØ help
• Provide analysis of Installation Risks
• Incorporate new information from L0 and
  Trigger hardware development teams, 2004 Shutdown
  experience

2004 Shutdown Activities Related to Installation

• Upgrade Installation Infrastructure tasks
  accomplished during 2004 Shutdown (in CH or MCH)
• L1 Cal None scheduled
• L1 CalTrack begin mods of Muon PDT and
  Scintillator FEBs, terminate L1CTT transition
  and MTCxx cables
• L1CTT - install parallel slice crate,
  controller, few DFEAs, cables for CTOC, CTT
• L2 Beta None scheduled
• L2 STT None scheduled
• L0 Silicon L0 clearance survey, adapter card
  and 4-Hybrid SVX4 string, NS mini fuse panels,
  new Wiener PS, Interlock chassis
• Online Move Online (DAQ, Oracle, NFS) to new
  host cluster

Beam-Off Time Paced by Silicon

• Present Installation Schedule shows Tevatron
  Shutdown Time driven by Layer Zero Silicon
  Installation
• Detector Not Removed From Collision Hall
• 2004 Shutdown experiences verifying silicon
  clearance are leading to reconsiderations of
  installation plans gt Revising existing schedule!
• Consideration of each installation step,
  appropriate (repeated) repositioning of End
  Calorimeter(s) and installation of precision
  fixturing, indicates L0 Installation requires 12
  weeks.
• Resume Tevatron operations in week 13 with
  opportunity to re-enter CH during L0 technical
  commissioning.
• 14th week required to close detector and make
  final survey
• Workweeks are standard 40 hours, five days
• Silicon installation dominates CH access time.
  Trigger Elements require lesser amounts of CH
  access in time shadow of L0.

Identified Additional Manpower Needs

• L0 Installation Expert Engineer Youri Orlov
• L0 Installation Expert Instrumentalist Mike
  Roman
• L0 Installation Expert Technicians Dave Butler,
  Dennis Graham
• CTT Expert Jamieson Olson
• Two Computer Science Professionals
• L1 Cal University Engineers Dan Edmunds,
  Phillipe Laurens
• Four Electrical Techs for two weeks for PDT mods
• Costed in schedule, important to have the named
  individuals

Installation Costs

• Burdened FY05/FY06 Installation Costs

14
Installation Risk Analysis

• Schedule Risks from Unanticipated Difficulties
  Encountered during L0 Installation substantially
  ameliorated by
• 2004 shutdown clearance survey
• Experience with survey instruments in gaps
• Handling of ECs and beampipe open-up/reclosing
• Careful design of and practice with Installation
  Tooling beforehand
• Involve personnel with previous DØ SMT experience
  where possible
• No second shift or overtime work currently
  scheduled
• MSProject Installation Management Tool
• Risk from Accidental Handling Damage to L0 during
  Installation substantially ameliorated by
• RunIIa Experience
• Will develop detailed step-by-step plans for
  every aspect of the work
• Involve personnel with previous DØ SMT experience
  where possible
• No second shift or overtime work currently
  scheduled

Installation Risk Analysis

• Schedule Risk from prolonged Commissioning of
  L1Cal substantially ameliorated by
• Careful non-invasive handling of fragile BLS
  cable installation (1280 coax cables under MCH1
  floor, gt15 years old)
• Preparation of BLS/ADF patch panels to
  facilitate reconnection to new ADFs
• Test Site on DAB Sidewalk full system to be
  operated using collider data input prior to
  shutdown
• Test data at L2 and L3 thoroughly verified
• Operating software to be exercised

16
Installation Risk Analysis

• Schedule Risk from prolonged commissioning of
  L1CTT substantially ameliorated by
• Parallel Chain Slice Test installed in 2004
  Shutdown to enable system level operation of real
  hardware (crate, crate controller, DFEA2s)
• Full test of system software (download, monitor,
  diagnose)
• Test that new hardware loaded with present
  doublet equations gives identical results to
  current trigger
• Test/optimize (effic. vs rate) algorithms with
  real data
• Schedule Risk from prolonged commissioning of
  L1CTM substantially ameliorated by
• Single Button running in global runs with real
  production CalTrack boards prior to shutdown

17
Conclusions

• Installation Management Team in place
• SC-IPC up and running to monitor physics
  commissioning planning and manpower scheduling
• Evolution of Schedule Continues
• Tasks detailed to sixth sublevel
• Resources (Effort, MS) loaded
• WBS Dictionary and BOE in place
• Timeline assumptions depend on availability of
  identified personnel
• Schedule refinements underway as planning evolves
• DØ prefers Tevatron shutdown that begins after
  all upgrade components are ready (to minimize
  integrated luminosity cost)
