CV M. Tyndel ( ….. 1972 – 2005 ….) “the Rutherford trail”
• First degree in NZ (birthplace of Ernest Rutherford)– “Search for quarks in cosmic rays”
• PhD in Rutherford building, Cambridge (1894-1898; 1919-1937)– “Properties of the K0 meson using 2m bubble chamber”
• Post-doc at Rutherford Laboratory– “Neutrino physics using bubble chambers”
• Technical adventures at RAL and CERN– Upgrade external Muon system for BEBC– Small diversion into solar neutrinos– Calorimetry for DELPHI– b-tagging studies & design & development of first collider vertex detector– ATLAS SCT– Electronics (DSM) and pixel development (MAPs)
• …. & then the ‘leader’ phase– Project leader DELPHI Micro-vertex CERN– Group leader RAL tracking– Project leader ATLAS SCT tracker

Activities of the ATLAS tracking group
• Past (1992 - )– Design of the ATLAS SCT
– Established the CCLRC clean room facility in R12
– Assembled & tested >700 silicon modules & >900 hybrids
– Designed & built support structures & cooling
– Assembled & tested Optical links & power tapes
– Engineering (~30 EID people involved)
• Present (2005)– Integrating SCT into ATLAS
– Installing services & getting SCT ready for physics
– Preparing Readout & DAQ
• Future (2006 – )– Commissioning & data-taking
– Physics
– Preparing an Upgraded tracker for 2015
• 10x more channels 2015
2007 Up to 1000 tracks
1 billion collisions/sec
10 billion collisions/sec

Tracking in ATLAS
• Barrel = 4 Carbon cylinders tiled with silicon detector modules
B6 • 2 Endcaps = 9 Carbon discs tiled with
silicon detector modules
D5
• SCT = Silicon tracker; a device to measure tracks precisely (~20m)
