Several firms available in Europe and interested. 2 LBNF Far Site Facilities Scope and Requirements Scope Element Funding Source Excavation of 4850L detector and utility caverns and drifts DOE Surface buildings, utility infrastructure, cavern outfitting DOE LN2 cryogenic systems DOE Four 10kt fiducial cryostats Non-DOE LAr cryogenic systems Non-DOE LAr and LN2 cryogenic fluids procurement DOE and Non-DOE CD-3a Scope • CERN is doing the final design of the cryostats, in contact with the LNG industrial community. We are constructing large prototypes (-> ProtoDUNEs). • CERN has accepted to finance the first cryostat construction. • We have the opportunity to build a consortium with several FAs for cryostat number 2. Several EU firms can be involved. • There are plenty of opportunities to participate in the engineering of the cryostats, in particular for all the penetrations to the liquid. • Same for the LAr cryogenics. We could effectively use the EU knowledge 3 LBNF and market. In practice: - We need to engineer an European in-kind for the second cryostat: - involve European firms in the various procurements - more engineering effort (distributed also outside CERN) - Prepare the installation scenario (technical teams, QA teams, ….) - All this can start with teh first cryostat - We need to engineer an European in-kind for LAR cryogenics: - involve European firms - We need to strength the CERN cryogenics group - Distribute the engineering design work also outside CERN - Work out the scenarios for installation and commissioning 4 LBNF
