The Long-Baseline Neutrino Facility

Montanari, David


The Deep Underground Neutrino Experiment (DUNE) collaboration is developing an international multi-kiloton Long-Baseline Neutrino experiment to be located about a mile underground at the Sanford Underground Research Facility (SURF), in Lead, SD, USA. In the current configuration four cryostats will contain a modular detector and a total of 68,400 ton of ultra pure liquid argon, with a level of impurities lower than 100 parts per trillion (ppt) of oxygen equivalent contamination. The Long-Baseline Neutrino Facility (LBNF) provides the conventional facilities and the cryogenic infrastructure (including the cryostats housing the detector) to support DUNE. This contribution presents the modes of operations, layout and main features of the LBNF cryogenic system.
The system is comprised of three sub-systems: External/Infrastructure (or LN2), Proximity (or LAr) and Internal cryogenics. The External/Infrastructure provides the infrastructure and equipment to store, produce and distribute the cryogenic fluids needed for the operation of the Proximity Cryogenics, which delivers them to the Internal at the pressure, temperature, mass flow rate, quality and purity required by the detector inside the cryostat. ... mehr
