Paris –
October
6th,
2022. GTT announces that it has been awarded a
contract by the Lawrence Berkeley National Laboratory to support
research work for the Deep Underground Neutrino Experiment1
(“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 cryostat2 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 CERN3, on behalf of the LBNF/DUNE4-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.
Philippe Berterottière, Chairman and CEO
of GTT, declared: “This new contract showcases the
reliability and flexibility of the technologies developed by the
GTT group. We are proud to provide technologies that can meet the
technical and scientific requirements of the DUNE project, and to
work with the Lawrence Berkeley National Laboratory, one of the
most prestigious National Laboratories in the United States.”
Fabrice
Matichard, Lead Engineer
for the LBNF/DUNE-US Near
Detector Subproject and Head of
the Lawrence Berkeley
National Laboratory Mechanical Engineering
department 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.”
