LHC Detector Alignment Workshop

4 Sept 2006, 08:00 → 6 Sept 2006, 18:00 Europe/Zurich

40-SS-D01 (CERN)

The four LHC experiments, ATLAS, ALICE,CMS and LHCb are organizing a LHC Alignment workshop from the 4th to 6th of September. The workshop will be held at CERN. The goal of the Workshop is to provide a forum to share ideas and information on the issues related to alignment of detectors, with particular emphasis on tracking detectors. The general program of the workshop will highlight four main areas: * Discussion of mathematical and statistical methods as they apply to alignment * Lessons from previous experiments * Alignment plans for LHC experiments, both hardware & software * Constants management (storage & retrieval ), software-enabling tools, tools for simulating misalignments, etc More information about the workshop can be found at the workshop home page: http://cern.ch/LHC-Detector-Alignment-Workshop  Workshop organizing committee: Oliver Buchmuller, Teresa Rodrigo (CMS) Jochen Schiek, Salvador Garcia (ATLAS) Adam Jacholkowski,Karel Safarik (ALICE) Steve Blusk, Thomas Ruf, Sebastian Viret (LHCb)
