Outsourcing strategy and tendering methodology for the operation and maintenance of CERN’s cryogenic facilities
/ Serio, L (CERN) ; Bremer, J (CERN) ; Claudet, S (CERN) ; Delikaris, D (CERN) ; Ferlin, G (CERN) ; Ferrand, F (CERN) ; Pezzetti, M (CERN) ; Pirotte, O (CERN)
CERN operates and maintains the world largest cryogenic infrastructure ranging from ageing but well maintained installations feeding detectors, test facilities and general services, to the state-of-the-art cryogenic system serving the flagship LHC machine complex. A study was conducted and a methodology proposed to outsource to industry the operation and maintenance of the whole cryogenic infrastructure. [...]

CERN operates and maintains the world largest cryogenic infrastructure ranging from ageing installations feeding detectors, test facilities and general services, to the state-of-the-art cryogenic system serving the flagship LHC machine complex. After several years of exploitation of a wide range of cryogenic installations and in particular following the last two years major shutdown to maintain and consolidate the LHC machine, we have analysed and reviewed the maintenance activities to implement an efficient and reliable exploitation of the installations.

New Operation and Maintenance Contract for Electrical Network
/ Kowalik, G
The Electrical Exploitation is one of the few remaining operation services at CERN which nearly entirely relies on the CERN staff. Last year CERN policy, in connection with the LHC project needs, have led to the formulation of the strategy of out-sourcing of the Electrical Exploitation activities, market survey and subsequent Invitation to Tender.

A New Cryogenic Test Facility for Large and Heavy Superconducting Magnets
/ Serio, Luigi (CERN) ; Schnizer, Pierre (Darmstadt, GSI) ; Arnaud, Michel (CERN) ; Bertone, Caterina (CERN) ; Blanco, Enrique (CERN) ; Calcoen, Daniel (CERN) ; Charrondiere, Maryline (CERN) ; Cho, Eun Jung (Darmstadt, GSI) ; Coelingh, Gert-Jan (CERN) ; Dahlerup-Petersen, Knud (CERN) et al.
CERN has recently designed and constructed a new cryogenic facility for testing large and heavy superconducting magnets at liquid helium temperatures. The facility, erected in a large assembly hall with cranes capable of up to 100 t, provides a cooling capacity of 1.2 kW at 4.5 K equivalent, 15-kW LN$_2$ cooling and warming capabilities for up to three magnets in parallel.

A Smart Framework for the Availability and Reliability Assessment and Management of Accelerators Technical Facilities
/ Serio, Luigi (CERN) ; Antonello, Federico (Milan, Polytech.) ; Baraldi, Piero (Milan, Polytech.) ; Castellano, Andrea (CERN ; Milan, Polytech.) ; Gentile, Ugo (CERN) ; Zio, Enrico (Milan, Polytech.)
CERN operates and maintains a large and complex technical infrastructure that serves the accelerator complex and experiments detectors. A performance assessment and enhancement framework based on data mining, artificial intelligence and machine-learning algorithms is under development with the objective of structuring, collecting and analysing the operation and failure data of the systems and equipment, to guide the identification and implementation of adequate corrective, preventive and consolidation interventions.
