End Cap ToroidsEnd Cap Toroids
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
Company claims cost overruns

Alignment
Key issue: RASNIK 3-point monitorStatus: Sensors delivered to MDT sites; DAQ prototypedOutstanding: Radiation tolerance of the multiplexers (first test: ok!)Difficulties: Cost (mechanics!) & lens quality (finally understood!)
Many other interested parties

Muon-Spectrometer: Detector Muon-Spectrometer: Detector ControlControl
Detector control (NIKHEF/CERN R&D collaboration)
Key issue: Modular: CAN CPU with many sensor types precise Hall B-sensors; cheap T-sensors, …Status: Being delivered to MDT sitesOutstanding: Radiation tolerance of the CAN CPUs
Used also by: D0, Saclay,
CMS(?), LAr (H8), …

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
