CERN Accelerating science


The mandate of the CV group concerns the design, installation, operation and maintenance of the cooling systems, pumping stations, air conditioning plants and fluid distribution systems for the PS, SPS and LHC including their experimental areas and special cooling systems of LHC sub-detectors. It also provides service to the Computer Centre and some miscellaneous installations.

The LHC and Injector sections perform maintenance works to enhance the reliability of the CV installations. To do so, the GEM section improves continuously maintenance strategies and, in particular, it renews the maintenance plans at equipment level, it completes the documentation and create M&O oriented dossiers including detailed working procedures that allow the subcontracting of M&O work to external contractors. The M&O work is based on a CMMS tool in order to improve the operations.

A dedicated design section (Bureau d'Etudes) is in charge of the creation and updating of technical drawings. The project section (PJ) is in charge of the management and completion of projects for new installations upgrade or consolidation of existing ones. The group performs also studies for future accelerators after the LHC as well as CFD simulations of fluid dynamics and heat transfer problems. The CV group also has the responsibility for the M&O of the LHC Experiments specific cooling equipment and the development of future prototypes and their production.


The control section (CL) is in charge of the design, development, commissioning and support of control systems for CV plants.
