ATLAS and CMS trackers operate almost perfectly: 99%/98% of 6.3M/9.3M strips working This was a long way, since the mid 1990s: R&D design choices lab-tests, beam-tests, system-test,… careful assembly careful commissioning and operation German groups: ATLAS: Freiburg, MPI Munich CMS: Aachen, DESY, Hamburg, Karlsruhe 5.12.2012 Lutz Feld | RWTH Aachen

Key developments: large area silicon strip sensors able to operate up to 500V bias voltage radiation-tolerant read-out ASCIs (ABCD/APV) optical read-out and communications low-mass support structures and cooling logistics! 5.12.2012 Lutz Feld | RWTH Aachen

Why upgrade current ATLAS and CMS trackers are specified to operate up to 1x1034cm-2s-1 instantaneous luminosity up to 500 fb-1 integrated luminosity HL-LHC will deliver from 2022 on 5x1034cm-2s-1 3000 fb-1 new tracking systems are needed higher hit densities (5-10 times higher) higher radiation damage (5-10 times higher) contribution to first level trigger desirable time to design and build the current trackers 1996 – 2006 = 10 years 2022 - 10 = 2012 now! 5.12.2012 Lutz Feld | RWTH Aachen

Proposal: Collaboration of German ATLAS and CMS Tracker groups on Enabling Technologies for Silicon Microstrip Tracking Detectors at the HL-LHC during the R&D phase key areas of mutual interest sharing experience alliance funding is very valuable and visible since BMBF funding for tracker upgrades is still rather limited 5.12.2012 Lutz Feld | RWTH Aachen
