Commissioning Status Plans

• Jae Yu
• All DØ Meeting
• Dec. 1, 2000

• What have we been doing?
• What is the status?
• What are the goals for the next few weeks?
• The end game?
• Conclusions

What have we been doing??

• Weve been keeping up with our philosophy of
  Commissioning components in their final Run II
  form!!
• Detector construction has been winding down
• Detector assembly and installation coming along
  nicely
• Physicist shifter contributions have been
  extremely valuable in making significant progress
  in establishing infrastructure
• Completing SiDet 10 test HV and readout cabling
  shifts
• Completing fiber optic laying Tracker readout
  cables
• Completing Wave guide QC at Lab3
• Preparing cable bundles and labeling them
• Replacing calorimeter BLS back-planes
• Modifying Calorimeter BLS power supplies
• Testing MCM modules
• And much much more.

Current Shift Schedule
No X-Mas Shutdown this year!!!
4

• However.
• Tracker Readout electronics and Trigger hardware
  bottle neck
• Installation and electronics schedule leaves
  practically no time to commission significant
  portion of the detector
• But nothing can ever stop us from starting cosmic
  ray commissioning
• Weve had three workshops
• July 14 and Sept. 1 for SiDet 10 test stand
• Establish SDAQ calibration
• Cosmic ray data taking with SMT-S N Barrel
  Disk Module
• Nov. 16 for Integration workshop at DAB to
  prepare detector systems for Dec. cosmic ray run
  ? This workshop was an EXTREMLY successful one
• A lot of people worked very hard and made
  significant progress
• Virtually all systems are participating in
  commissioning
• We must squeeze out as much as we can, before the
  roll in

Nov. 16 Workshop Goals

• Primary goal Prepare detector systems for cosmic
  ray run
• Run Calibration on (Data taking and COMICS
  downloading)
• Calorimeter in L3/DAQ (Fill and turned on HV)
• SMT on SDAQ
• Muon
• Readout in the same event, triggered by cosmic
  scintillation counter coincidence and/or L1 m
• 1 Cetral Muon Scintillation counter crates
• 1 PDT Crate w/ 6 PDT
• 1 Forward Pixel Crate
• 1 MDT crate
• 1 Cal crates
• 3 SMT crates
• 1 CFT crate
• 1 TFW crate

Total of 10 crates
7

• Run online Examines on Control room Linux
  machines
• Calorimeter Cal elec
• Central Forward Muon
• SMT
• CFT
• Global
• Run online event display
• Muon
• Calorimeter
• Integrate SR for multi-run per node functionality
• Ship data to SAM
• Run offline reconstruction at FCC
• Need Run configuration information
• Need cable maps

Dec. 14Start cosmic ray commissioning

• Readout Cosmic Ray hits from 2 Axial Layers of
  CFT super sector 2 WAMUS FAMUS Systems
• Readout Cosmic Hits in gt1/2 CC and ICD (Cal
  Trigger)
• Complete integrating L3 Muon Filter and Streaming
• Readout Noise from partial SMT-S perform
  coherent noise study, especially the effect to
  Calorimeters (Read out all 12 crates)
• Reconstruct Muon Tracks
• Test offline streaming and check functionality,
  eg Lum blocks
• Run offline reconstruction farm as data is
  shipped over, using proper calibration
  information
• Display events using FULL online event display

Cosmic Ray Commissioning Run

• Duration Dec. 14 Roll in (26 days, assuming
  Jan 15 roll-in)
• Primary goals
• Check out the detector as one integrated unit
  every day
• Subject as many parts of the detector as possible
  to long term stability tests
• Will have a workshop on Thursday, Dec. 14 to
  prepare
• Iron out all the remaining little bugs
• Another integration of all available systems
• Clear and comprehensive shifter instructions and
  tools for feed back
• Daily task lists for evening and owl shifts
• Shifts cover 6pm-2am and 2am-10am M-F, 24 hrs
  Sat. Sun (Except for Dec. 23, 24, 25, 31, and
  Jan 1) ? Need a total of 32 shifts/wk
• Detector installation, debugging, and
  commissioning continue during the day

13
End Game?

• Given the current schedule of electronics
  Installation
• No chance to check out most the electronics
  outside the collision hall
• Prepare for worst case scenario
• Detector rolled in w/
• Partially cabled SMT-N and H-Disks
• Electronics checkout in progress w/ incremental
  installation
• Partial L1 trigger (Cal and muon?)
• No L2/L3 trigger hardware to handle rates
• Beam starts rotating in the Tevatron most of the
  day
• Installing Checkout of the electronics is a
  nightmare
• Need to prepare for good tools for fast
  turn-around and feed back
• Need to increase number of experts to cover three
  shifts
• Shifters must help out debugging
• Will take much longer to bring up the detector

14
Conclusions

• Significant progress has been made on all fronts
• A few dedicated people are working very hard
• Detector installation making good progress
• Electronics are serious concern ? Worried that we
  might not have had a chance to look at some parts
  before roll-in
• Detector checkout need to keep up with
  installation and hook up
• Cosmic ray run must be carried out as long as we
  can
• These 26 days are the only thing weve got before
  the roll in
• This is the model for our collider run operation
• Need to accumulate experiences w/ detector running

15
So lets Roll up our Sleeves and Participate in
getting the Experiment brought up!!!!
16
Who can help?

• Experts installing and commissioning sub-detector
  systems must continue their job, interacting with
  engineers Techs.
• Given the current stability of the system, it is
  better if we can have a few dedicated people for
  this shifts ? One can imagine these Experts be
  the run guiders at the beginning of the run
• This means
• Anyone who does not need to interact with
  Engineers and Techs
• Anyone who wants to learn detector systems in the
  field
• Anyone who wants to get into the action
• ?In other words, every single one of you can do
  this
• Send me (yu_at_fnal.gov) e-mail by next Wednesday,
  Dec. 6, for shifts ? Will prepare some tutorial
  sessions
