LBNF Long-Baseline Neutrino Facility LBNF Cryogenics (Current status) David Montanari Cryogenic Instrumentation & Slow Controls Joint Consortium Meeting 22 December 2017
Outline • Introduction. • Proximity Cryogenics in Detector Cavern. • Internal Cryogenic. • Cryostat feedthroughs. • Proximity Cryogenics in CUC. • LN2 Refrigeration System. • Lar/LN2 Receiving Facilities on surface. • Next Steps. 2 12.22.17 David M. | LBNF Cryogenics (Current Status) LBNF
Introduction • Technical talk, no funding considerations. • Information is current and design a draft/work in progress. • Different design maturity for various parts. • Designs based on LBNF/DUNE requirements and real size components. • All items transportable down the Ross Shaft. • Preliminary installation sequences thought out (to be finalized). • Lifting eyes on roof of Detector’s cavern and CUC for equipment lifting and positioning. • Goal of design effort is to prepare design packages that could be procured, by DOE and non-DOE parties. 3 12.22.17 David M. | LBNF Cryogenics (Current Status) LBNF

LN2 Refrigeration System The LN2 refrigeration system Big Compressors did not change. on Surface • 4 Commercial units: - Cold boxes and gas boosters in the cavern. Cold boxes & Expanders - GN2 compressors above ground. Underground • Units assembled in cavern, based on transport limits. • 3 units for cryostats 1, 2 and 4 th unit added for cryostats 3, 4. • 4x97 kW units. • Piping in shaft is CF responsibility. 15 12.22.17 David M. | LBNF Cryogenics (Current Status) LBNF
LAr/LN2 Receiving Facilities Proposed additional temporary LAr Current Cryogens Storage and Vaporizers (LAr fill only) Storage and vaporizers LN2 System Compressors Building LAr Storage Tanks LN2 Storage Tank and Vaporizers and Vaporizer 16 12.22.17 David M. | LBNF Cryogenics (Current Status) LBNF
Next Steps • Proximity Cryo in Detector’s cavern: - Continue to add details to the cryogenics on the mezzanine. - Prepare design documentation (Technical Specifications, 3D models with not-to-exceed envelopes, etc.) for non-DOE parties to take on. - Implement new LAr pumps model (in progress). • Internal Cryogenics: - Update the height over the floor, if needed. - Discuss with stakeholders and finalize the design. - Prepare design documentation (Technical Specifications, 3D models with not-to-exceed envelopes, etc.) for procurement process. • Proximity Cryogenics in CUC: - Continue to prepare design documentation for LAr Purification #1:ICDs, Functional Requirements Specifications for LAr Purification Vessel. - Prepare same documentation for Gar Purification #1, #2 and Regen #1. • LN2 Refrigeration System: - Continue the iteration with DOE on AP and RFP docs. - Issue RFP, get bids, evaluate bids, and select a vendor. - Award contract for design (full system) and fabrication of first 3 units. • LAr/LN2 Receiving Facilities: - Finalize the amount of LAr storage (in consultation with potential LAr vendors). - Prepare AP and RFP docs and iterate with DOE. - Issue RFP, get bids, evaluate bids, and select a vendor. - Award contract for design (full system) and fabrication of first 3 units. 17 12.22.17 David M. | LBNF Cryogenics (Current Status) LBNF
