November 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


DD 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


DD 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


DD Detector Rolled in and Hooked Up

February 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
