Description
The cryogenic infrastructure at CERN was originated in the 1960s by bubble chambers and the associated superconducting solenoids. Since then, complex cryoplants have been installed to provide cooling power from 400 W to 18 kW at 4.5 K, requiring high technical capabilities from the control system. The LHC cryogenics has recently adopted the CERN standard control framework UNICOS in order to enhance ease of operation and maintenance and to provide long-term durability. After the completion of the LHC construction, CERN has undertaken a large project for the upgrade of the obsolete control system (total of 15) of helium cryoplants cooling superconducting magnet of various CERN detectors as well as large cryogenic test facilities. This paper describes the technical procedure used in order to meet the technological challenge in term of installation constraint, reduced manpower and minimal costs. Some examples are given.
