Dark matter is also in the process of being detected via underground detectors (to prevent noise from cosmic rays).
Other research in the laboratory and with underground detectors, searching for neutrinos from the sun and in cosmic rays, has produced preliminary results suggesting that some neutrinos have mass.
At the instant the explosion occurred, a flood of neutrino particles was released and simultaneously recorded by underground detectors in Japan and the United States.
To link the surface GPS location to the coordinates of the underground detector, traffic had to be partially stopped on the access road to the lab.
The clock value noted above-ground had to be transmitted to the underground detector with an 8 km fiber cable.
Fermi will search for evidence that dark matter is composed of weakly interacting massive particles, complementing similar experiments with the Large Hadron Collider and other underground detectors.
(That accelerator has its own set of four underground detectors, each much smaller than Atlas.)
Dark matter particles could accumulate in the Sun or Earth and annihilate, producing neutrinos observable in large underground detectors.
Worldwide Efforts To Unlock Secrets Members of the Kamiokande collaboration have not limited their investigations to huge underground detectors.
Fermilab is a leader in the search for dark matter and dark energy at both underground detectors and ground-based telescopes.
