Description
The Short-Baseline Neutrino (SBN) physics program at Fermilab and Neutrino Platform (NP) at CERN are parts of the international Neutrino Program leading to the development of Long-Baseline Neutrino Facility/Deep Underground Neutrino Experiment (LBNF/DUNE) science project. The SBN program consists of three LAr-TPC detectors positioned along the Booster Neutrino Beam (BNB) at Fermilab. The first of these, the MicroBooNE collaboration detector (170 ton LAr mass) was constructed 2011-2014 and operating since 2015. The SBN’s Near Detector (SBND or NP03, ~ 260 ton) is presently under construction. The SBN’s Far Detector (SBN-FD or NP01, ~ 600 tons) is the ICARUS collaboration T600 LAr-TPC, previously operated in Europe and being shipped to Fermilab in 2017. All three LAr-TPC detectors have distinctly different design of their LAr cryostats thus defining specific requirements for the cryogenic systems. CERN and Fermilab are collaborating on the design of the SBN cryogenics while dividing delivery responsibilities for proximity, external and internal subsystems of each detector. CERN is responsible for delivery of the proximity subsystems for all detectors while Fermilab is responsible for delivery of external subsystems, internal subsystem for SBND and integration of subsystems via common safety and controls for all detectors. This contribution presents specific design requirements and typical implementation solutions for each subsystem of the SBND and SBN-FD cryogenic systems.
