End Cap Toroids
4
Muon-Spectrometer Alignment
Alignment Key issue RASNIK 3-point
monitor Status Sensors delivered to MDT sites
DAQ prototyped Outstanding Radiation tolerance
of the multiplexers Difficulties Cost
(mechanics!) lens quality
Many other interested parties
5
Muon-Spectrometer Detector Control
Detector control (NIKHEF/CERN RD
collaboration) Key issue Modular CAN CPU with
many sensor types precise Hall
B-sensors cheap T-sensors, Status Being
delivered to MDT sites Outstanding Radiation
tolerance of the CAN CPUs
Used also by D0, Saclay, CMS(?), LAr (H8),
6
(Muon-Spectrometer) Read-Out Driver
Read-Out Driver Difficulty Cost (RODCSM
doubles CORE) Status RD phase Test bed cosmic
ray set-up

Summary

• ATLAS efforts on realization of CORE commitments
• (We realize our participation in ATLAS physics
  studies is not in line with our ambition )
• Muon Spectrometer
• End cap Toroids
• Vacuum vessels progressing well (minor delays)
• Coil winding company claims cost overruns
• MDT chamber construction
• RD basically completed (and it took a lot of
  time)
• Huge serial production effort in 2001-2005
• Alignment, Detector Control MDT Read-Out
  Drivers
• Completed or near completion
• Point of concern radiation tolerance
• Silicon Tracker
• Design closure urgently required (else we get
  squeezed)
• Significant assembly test effort in 2002-2003/4
