GTT membrane technology to equip a great international scientific project, the Deep underground neutrino experiment
Paris – October 6the, 2022. GTT announces that it has been awarded a contract by the Lawrence Berkeley National Laboratory to support the research work of the Deep Underground Neutrino Experiment1 (“DUNE”) under the auspices of the US Department of Energy Fermi National Laboratory (“Fermilab”). Under this contract, GTT will provide the engineering and construction studies for the adaptation of its membrane technology inside a cryostattwo designed by Lawrence Berkeley National Laboratory and partners.
DUNE is a large international experiment that aims to increase understanding of neutrinos. The project harnesses neutrinos produced by the Long Baseline Neutrino Facility (LBNF) at Fermilab, which are then analyzed in liquid argon-filled particle detectors. The liquid argon used in this experimental context must be kept at an extremely stable temperature of -186 °C, in an environment that ensures, through perfect hermeticity, the purity of the materials and a high level of thermal insulation.
This new contract follows the one signed by GTT in 2018 with CERN3on behalf of the LBNF/DUNE4-US project. Within the framework of this previous collaboration, GTT contributed with the final design of the far sensing cryostats. The new contract will focus on the design of the inner vessel installed within a warm support structure for the nearby liquid argon detector.
Philippe Berterottière, President and CEO of GTT, stated: “This new contract To showaces the reliability and flexibility of the technologies developed by the GTT group. We are proud of provide technologies that can meet the technical and scientific requirements of the DUNE Project, Y youworked with the Lawareness B.erkeley northnational Llaboratoryone of the most prestigious National Laboratories in the United States.”
Fabrice maticard, LBNF/DUNE-US Chief Engineer Close Detector Subproject and Responsible for Lawrence berkeley national laboratory Department of Mechanical Engineering stated: “Our collaboration with GTT will provide the membrane technology for the liquid argon detector. This new cryostat design incorporates features such as the ability to travel on rails and a low density composite wall to probe neutrinos with the level of precision required by the DUNE experiment.”
GTT is a technological expert in cryogenic membrane containment systems for the transport and storage of liquefied gases. For more than 50 years, GTT has been designing and providing state-of-the-art technologies for better energy performance, combining operational efficiency and safety, to equip methane tankers, floating terminals, shore storage and multi-gas vessels. GTT also develops systems dedicated to the use of LNG as a fuel, as well as a full range of services, including digital services in the field of Smart Shipping. The Group is also active in hydrogen through its subsidiary Elogen, which designs and assembles electrolysers, in particular for the production of green hydrogen.
GTT is listed on Euronext Paris, Compartment A (ISIN FR0011726835 Euronext Paris: GTT) and is included in particular in the SBF 120, Stoxx Europe 600 and MSCI Small Cap indices.
