J-4 - Internal Cryogenics - App C - Internal Cryogenics Interface Matrix.xlsx

This document is an interface matrix for the internal cryogenics system of the LBNF (Long-Baseline Neutrino Facility) project. The matrix provides detailed technical specifications for thirty cryogenic transfer lines and their supports required to transfer liquid and gaseous argon within the DUNE (Deep Underground Neutrino Experiment) cryostats. Key details include the pipe type, fluid, operating conditions, physical interface, and insulation requirements for each transfer line. The matrix covers recirculation, cool-down, emergency return, and boil-off lines. This technical information supports the LBNF-357777-JD solicitation for the engineering, manufacturing, and delivery of the internal cryogenics piping systems for the first two LBNF cryostats located at the Sanford Underground Research Facility in Lead, South Dakota. The successful bidder will be responsible for providing these cryogenic transfer line systems to the project.
