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.

LN2 Refrigeration System

12.22.17 David M. | LBNF Cryogenics (Current Status) 15

The LN2 refrigeration system did not change.

  • 4 Commercial units:
  • Cold boxes and gas

boosters in the cavern.

  • GN2 compressors above

ground.

  • Units assembled in

cavern, based on transport limits.

  • 3 units for cryostats 1, 2

and 4th unit added for cryostats 3, 4.

  • 4x97 kW units.
  • Piping in shaft is CF

responsibility.

Next Steps

12.22.17 David M. | LBNF Cryogenics (Current Status) 17

  • 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.
