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...

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...

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...

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...
