  1. 29. Welcome and introduction to CERN
    Dr Philippe Lebrun
    23/09/2008, 09:00
  2. 27. The world of cryogenics at CERN
    Dr Dimitri Delikaris
    23/09/2008, 09:30
    OPERATION
    Today at CERN, cryogenics is largely used in the LHC project under commissioning for cooling the 27 km magnet ring which requires the largest 1.8 K helium refrigeration and distribution systems in the world as well as its two largest detectors (ATLAS and CMS), which incorporate a variety of cryogenic equipment. In addition, cryogenics is used for cooling specific experiments not related to the...

  3. 28. LHC Cryogenics: Cool-down of the ring for commissioning and first beams
    Mr Serge CLAUDET (CERN)
    23/09/2008, 10:30
    OPERATION
    A recall of the LHC cryogenics architecture and hardware equipment will be given, including the organization and achievements for cool-down of the eight geographical sectors. The hardware commissioning procedures of the cryogenic system and machine will be described. A brief introduction to the preparation work in view of the first beam injection will be presented. Finally the long-term...

  4. 21. Design choices of the cryogenic system for the long-term operation of ATLAS and CMS detector magnets
    Mr Nicolas DELRUELLE (CERN)
    23/09/2008, 11:00
    OPERATION
    The design of detectors for High Energy Physic experiments is frequently based on large superconducting magnets generating the field for particle momentum measurements. The CMS experiment is built around a single large superconducting solenoid, whilst the magnetic configuration of ATLAS is based on a thin Central Solenoid surrounded by a large superconducting toroid consisting of three...

  5. 4. Continuous operation of liquefied noble gas calorimeters at CERN
    Dr Johan Bremer (CERN)
    23/09/2008, 11:30
    OPERATION
    Two experiments at CERN are demanding the continuous cooling (24h/24h, 365 days/year) of liquefied noble gas calorimeters: the NA48 experiment equipped with a 10 m3 liquid krypton calorimeter and the ATLAS experiment equipped with a 85 m3 liquid argon calorimeter housed in three independent cryostats. This presentation will focus on the design principles applied to allow for this highly...
