(Boursier.com) — GTT announces the award of a contract by the Lawrence Berkeley National Laboratory to support the research work of the Deep Underground Neutrino Experiment (“DUNE”) project, under the auspices of the Fermi National Laboratory (“Fermilab”) of the United States Department of energy. Under this contract, GTT is carrying out the engineering and construction studies for the adaptation of its membrane technology inside a cryostat designed by the Lawrence Berkeley National Laboratory and its partners.
This new contract follows the contract signed by GTT in 2018 with CERN, on behalf of the LBNF/DUNE-US project. As part of this previous collaboration, GTT contributed to the final design of the far detector cryostats. The new contract covers the design of the inner vessel, installed in a hot support structure, for the near detector.
DUNE is a major international research project that aims to better understand neutrinos. The project uses neutrinos produced by Fermilab’s Long-Baseline Neutrino Facility (LBNF), which are then filtered through particle detectors filled with liquid argon. The liquid argon used in this experimental context must be maintained at an extremely stable temperature of -186oC, in an environment guaranteeing, through perfect sealing, the purity of the materials and a high level of thermal insulation.
