  1. Program Introduction MDT Chamber Production Silicon Tracker Project Software & Physics Frank Linde (15’) Marcel Vreeswijk (25’) Nigel Hessey (25’) Stan Bentvelsen (30’) • Laboratory Tour: • MDT production line (20’) • SCT area (20’) • Lunch Peter Jenni @ NIKHEF, 22-June-2001

  2. ATLAS/D0 in Amsterdam & Nijmegen Medipix DataGRID (G measurement) ATLASD0 Staff 9 4 PostDoc 1 1 PhD 7 7 Students 1 1 Technical support: very good ATLAS contributions • Muon Spectrometer(hardware) • End Cap Toroids • MDT Chambers • Alignment • Detector Control • MDT Read-Out Driver • Silicon Tracker(hardware) • 100 modules • Disc design • Assembly & test of one complete end cap • Trigger & DAQ(hard- & software) • R&D participation

  3. End Cap Toroids Coil Winding (HMA power systems) Conductor delivery problematic; other materials & tools in place Negotiations on claimed cost overruns by the company ongoing 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)

  4. Muon-Spectrometer: Alignment On-chamber Off-chamber MasterMux USA15Mux CCD mask multiplexer lens 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 On-chamber CAN Network T-sensors 30 max T0.2 oC B-sensors B/B10-4 extra bus (insurance) digital busses to MDT front-end 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 sites Outstanding: Radiation tolerance of the CAN CPUs Used also by: D0, Saclay, CMS(?), LAr (H8), …

  6. (Muon-Spectrometer:) Read-Out Driver MDT chambers USA15 Surface TDC 1 TDC 1 CSM CSM MROD (NIKHEF) ROB CSM-Link 18 x 18 x 1.28 Gbit/s S-Link to ROB TDC 18 TDC 18 6 x CSM-Link ROD or ROB “OUT” CSM ROD or ROB “IN” Read-Out Driver Difficulty: Cost (ROD+CSM doubles CORE) Status: R&D phase Test bed: cosmic ray set-up

  7. Trigger & DAQ { spreadsheet & computer model: ROBs, networks & LVL2 processor farm design & studies of MDT-ROD/ROS MDT-ROD construction online software DCS software November 2001: Trigger, DAQ & DCS week @ NIKHEF

  8. 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: • R&D 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 • Trigger & DAQ: • Many R&D contributions; synergy with MDT-Read-Out Driver project
