GTT announced that it has been awarded a contract by the Lawrence Berkeley National Laboratory to support research work for the Deep Underground Neutrino Experiment (“DUNE”) under the auspices of the U.S. Department of Energy's Fermi National Laboratory (“Fermilab”). Under this contract, GTT will provide engineering and construction studies for the adaptation of its membrane technology inside a cryostat designed by the Lawrence Berkeley National Laboratory and its partners. DUNE is a major international experiment that aims to increase the understanding of neutrinos.

The project takes advantage of the neutrinos produced by the Long-Baseline Neutrino Facility (LBNF) at Fermilab, which are subsequently screened in the particle detectors filled with liquid argon. Liquid argon used in this experimental context has to be maintained at an extremely stable temperature of -186°C, in an environment that secures, through perfect tightness, the purity of materials and a high level of thermal isolation. This new contract follows the contract signed by GTT in 2018 with the CERN, on behalf of the LBNF/DUNE-US Project.

In the framework of this previous collaboration, GTT contributed the final design of the far detector cryostats. The new contract will focus on the inner vessel design installed inside a warm support structure, for the liquid argon near detector.
