5. Magnet development process 2013-12-12 MSC Technical Meeting5 Physics Community From needs, formulate functional requirements Functional & operation requirements  Prototyping Engineering design of an accelerator magnet (full-length, with all necessary features for “accelerator”: bus bars, protection, geometry and alignment, vacuum, cooling, cold mass envelope, interfaces, …) Analysis, tooling, integration-interfaces, constraints Full-length prototype fabrication and testing in real operation conditions, in view of validating the design Interactions with physicists, and partner technologies (vacuum, cryogenics, cryostating, power supply, protection, …) Prototyping  Final Design For series production Taking into account industrial constraints Interaction with industry New, and innovative concept Functional requirements  Conceptual Design Research & Development Cable development Electro-magnetic & mechanical analyses Material selection and testing Tooling development Short model fabrication and testing in view of validating the concept Demonstrator

6. Concept Have companies experienced in the field of superconducting accelerator magnet technology working with/at CERN on the prototyping and industrialization of Nb 3 Sn magnets for HL-LHC Through special industrial service contracts The standard Field Support Unit (FSU) contracts do not provide answer to our specific needs because they are too generic 2013-12-12 MSC Technical Meeting6

7. Objectives 1. Compensate the temporary lack of resources due to the LS1 Project (consolidation of the LHC machine) 2. Understand better, at an early stage, the inevitable constraints of the industrial world, and adapt the final design as needed, wherever possible 3. Make use of the know-how and specific expertise of specialized firms 4. Anticipate technology transfer towards industry a) To avoid unnecessary margins aimed covering unknowns/uncertainties @ bidding stage b) To prepare industry for the future series production of a new type of superconducting magnets c) To shorten, as much as possible, the duration of the learning phase in the beginning of the production 2013-12-12 MSC Technical Meeting7

8. Procurement process 2013-12-12 MSC Technical Meeting8 Market Survey [to well known companies, #10] Technical description [short], tech. questionnaire, and qual. criteria Identification of suitable bidders within the CERN member states Invitation to tender [to qualified bidders, #7] Technical specification, and annexes [checked by TS Committee] Work packages, and qualifications of personnel defined Tender form, hourly rates, offers for 3600 hours/year over 2 years Offers [#5] and contracts award [#4] Adjudication based on lowest bid Submission to CERN Finance Committee for approval (3 contracts proposed) Finally, 4 contracts were given to 4 different firms in 4 different countries Brainstorming: how do we do it? What do we need/ask? What scope? What adjudication criteria? Risk? How to ensure we get quality service, how to evaluate our level of satisfaction, what quality indicators, how to keep things under control? Preliminary discussions conducted with the firms to ‘measure’ interest

14. Critical item: Intellectual property In application of the CERN General Conditions of Contract, all intellectual property generated during the execution of the contract will belong to CERN. Accordingly, CERN is free to give access to the results generated during the execution of the contract to third parties at its sole discretion. The contractor thus acknowledges that the results of work related to the prototyping and industrialization of Nb 3 Sn magnets will be made available to the successful bidder(s) for the series production. Furthermore, the contractor hereby agrees to grant CERN a royalty-free license on its pre-existing intellectual property needed to make use of the results generated during the execution of the contract, sub-licensable to third parties within the scope of CERN’s activities. The contractor shall provide to CERN a list of its pre-existing intellectual property needed to make use of the results generated during the execution of the contract within 60 days after signature of the contract. CERN hereby agrees to grant the contractor a license on the results for the commercial exploitation of the results beyond HL-LHC procurement at preferential conditions. 2013-12-12 MSC Technical Meeting14
