[2][3] The project assessed the feasibility of developing the observatory-infrastructure and the observatory particle detectors themselves, as well as looking for a deployment site (seven candidates) in Europe.
[1] The construction of DUNE started in 2017 in Sanford Lab in South Dakota, USA with expected completion 2027.
These noise particles do not penetrate the Earth at that depth, but the neutrinos that interact only weakly with normal matter do.
LENA (Low Energy Neutrino Astronomy) is a liquid scintillation detector with a mass about 50 kton.
[7] LENA's aim is to study low energy neutrinos originated by supernova explosions, Sun and Earth's interior.
