LBNF Liquid Argon LAr Circulation Equipment

2026-11-03

A brief summary of the scope is provided below . For complete details please download the Statement of Work attached to this notice . The LAr Circulation System VD and HD Equipment is responsible for transferring liquid argon coming from the Cryostat VD and Cryostat HD to the low - pressure suction side of the main LAr Circulation Pump ( not part of this scope ). It is also responsible for transferring liquid argon downstream of the main LAr Circulation Pump ( not part of this scope ) through the system resistance ( friction and internal losses in valves , piping , etc .) to the LAr Purification system . The selected vendor will engineer and manufacture the vacuum jacketed pump valve box ( part of the scope ) that will house the pump , the MLI insulated upstream and downstream piping , isolation valves , and instrumentation required for this operation laid out above . The cryogenic equipment in the Detector Caverns will need to be properly protected and accessible with the use of platforms , ladders , support beams and railings ( all part of this scope ). Scope Overview of the Supply StructureThe LAr Circulation System VD and HD acquisition is broken down into the equipment , valves and instrumentation that are detailed in the SOW • Vacuum Jacketed Pump Valve Box • MLI insulated upstream and downstream piping of the main LAr Circulation Pumps ( Pumps are not part of Supply )• Instrumentation • Isolation Valves • Pressure Safety Valves • Cryogenic Equipment Protection ( Platforms , Ladders and Supports
