Vacuum Vessels
(Schelde Exotech)
First Vessel: Assembly in progress to CERN: fall 2001 (6 months delay)
Second Vessel: Machining in progress to CERN: spring 2002 (on time)
Coil Winding
(HMA power systems)
Conductor delivery problematic; other materials & tools in place
Negotiations on claimed cost overruns by the company ongoing

ATLAS efforts on realization of CORE commitments
(We realize our participation in ATLAS physics studies is not in line with our ambition ………)
Muon SpectrometerEnd cap Toroids
Vacuum vessels: progressing well (minor delays)Coil winding: company claims cost overruns
MDT chamber construction:R&D basically completed (and it took a lot of time)Huge “serial” production effort in 2001-2005
Alignment, Detector Control & MDT Read-Out DriversCompleted or near completionPoint of concern: radiation tolerance
Silicon Tracker: Design closure urgently required (else we get squeezed)Significant assembly & test effort in 2002-2003/4
Trigger & DAQ:Many R&D contributions; synergy with MDT-Read-Out Driver project
