  1. Current Detector ConfigurationJune 6, 2000 • Solenoid, Central Preshower installed in central bore • A-layer MDTs installed on inner faces of end irons • Central muon system installed, being commissioned • South end calorimeter, end irons on sidewalk • North and south trusses in Hi Bay, being prepped for move to sidewalk • Central iron, north calorimeter in open positions to allow access • Shield wall up

  2. Current Detector ConfigurationJune 6, 2000 • South end calorimeter, end irons on sidewalk • A-layer MDTs installed on faces of end irons • Commissioning Level 1 trigger, muon system, online, silicon front-end, solenoid

  3. Install Fiber Tracker in SolenoidJune 16-29, 2000 • Fiber Tracker being installed in central bore • North A-layer pixel sheet mounted on shield wall • Commissioning of DAQ, online, central muon system, etc. continues

  4. Move Platform West, Pick Up End IronsJuly 11-28, 2000 • Fiber Tracker installed, south end calorimeter back in place on platform • Platform moves west to pick up two end irons • Detector buttoned up for move • Commissioning interrupted until platform returns east (services disconnected)

  5. Move Platform West, Pick Up End IronsJuly 11-28, 2000 • Platform moves west to pick up two end irons • Movable Counting House moves with detector during pick up • Assembled north A-layer pixel plane remains on shield wall

  6. North & South Trusses Move to SidewalkJuly 31 – August 25, 2000 • Platform returns to east position with end irons installed • North & south trusses, shielding brought down to sidewalks from Hi Bay, assembled • Detector remains buttoned up until trusses are down • Cabling of Fiber Tracker begins after south truss is in place • Platform services reconnected, commissioning resumes

  7. North & South Trusses Move to SidewalkJuly 31 – August 25, 2000 • Platform returns to east position with end irons installed • North & south trusses brought down to sidewalks • South calorimeter, end iron opens to allow cabling of Fiber Tracker • A-layer north pixel sheet mounted on shield wall, awaits installation

  8. A- & C-layer Pixels & MDTs InstalledNovember 10, 2000 • A- and C-layer detectors mounted • SMT-S installed, hooked up – SMT-N being installed • Trusses ready to install in Collision Hall • South calorimeter, end irons open to allow access to inter-cryostat region • Commissioning of CFT, SMT, Forward and Central Muon, attendant readout

  9. Trusses Installed in Collision HallNov 20 – Dec 11, 2000 • North & south ends of shield wall removed, blocks stacked in Hi Bay • Loaded trusses rolled into Collision Hall, surveyed • Platform remains in Assembly Hall, rolled in after trusses in place • Commissioning of detectors on platform continues

  10. Trusses Installed in Collision HallNov 20 – Dec 11, 2000 • Mounting of B-layer MDTs on outer faces of end irons near completion • North B-layer pixel plane assembled on shield wall • End cryostats/irons open as logistics allow • Cosmic ray commissioning & triggering using SMT, CFT, and muon

  11. Detector Rolled in and Hooked UpFebruary 16, 2001 • Platform rolled in to meet trusses • Full detector in final closed position: hooked up, ready for beam • Shield wall back up • Movable Counting House travels with detector, cable bridge down • Commissioning with cosmic rays continues until beam is delivered (March 1, 2001)

  12. Access to Detector in Collision Hall Closed Position - Data-Taking Open Position - Detector Access North B-layer pixels open North end iron closed South calorimeter open South end iron open Shielding retracted

  13. Forward Muon B-Layer InstallationMay, 2000 • End irons moved toward center of Assembly Pit to allow access for B-layer installation/surveying • Commissioning continues

  15. Trusses Assembled on North & South SidewalksJuly 21 – August 25, 2000 • Detector returns to east position with end irons installed • Trusses brought down from Hi Bay to sidewalks • Central irons, calorimeters remain closed for movement of trusses • Hookup of Fiber Tracker begins after south truss is in position • Commissioning resumes, begin integration of CFT

  16. Current Detector ConfigurationPhase I • A-layer MDTs, Pixels being mounted, surveyed onto faces of end irons • C-layer truss and shielding has arrived in Hi-Bay, being dressed • Remainder of detector remains open for access

  17. Current Detector Configuration • Commissioning continues, using Central Muon as prototype system: • Multi-crate readout of full central muon system • Event monitoring, crate control, steady DAQ running, filtering • Exercise reconstruction, online event display (on cosmic ray muons)

  18. Forward Muon B-Layer InstallationMay-June, 2000 • A-layer planes installed • B-layer MDTs, Pixels being mounted, surveyed onto faces of end irons • C-layer trusses and shielding continue to be dressed in Hi-Bay

  19. Install Fiber Tracker in SolenoidMay, 2000 • Fiber Tracker + Cart/I-Beam system lowered into gap between South End Calorimeter and Central Calorimeter • Rolled into solenoid bore along I-Beam Cart System Fiber Tracker

  20. EMCs Installed in Collision HallDecember 11, 2000 - January 11, 2001 • Shield wall is broken down, moved to now free space in Hi-Bay • North and South C-layer trusses/shields, having been assembled on sidewalk, rolled into Collision Hall - surveyed into place • Detector will be rolled into place to meet trusses

  21. EMCs Installed in Collision Hall • Full Cosmic Ray Commissioning of all systems continues during most of this period • End irons, calorimeters can be opened for access

  22. Detector Rolled In, Hooked UpPhase III • Detector installed in compact space • Access to internal tracking detectors, end muon detector planes must be carefully coordinated

  23. South EMC Truss Moves to South SidewalkNovember 29- December 5, 1999 • South C-layer truss moves to south sidewalk • EMCs, shielding re-assembled on sidewalk to prepare for rolling in

  24. South EMC Truss Moves to South SidewalkNovember 29- December 5, 1999 • South C-layer truss moves to south sidewalk in two pieces, reassembled • Preparing to take down shield wall for roll in
