The Homestake experiment was followed by other experiments with the same purpose, such as Kamiokande in Japan, SAGE in the former Soviet Union, GALLEX in Italy, Super Kamiokande, also in Japan, and SNO (Sudbury Neutrino Observatory) in Ontario, Canada. SNO was the first detector able to detect neutrino oscillation, solving the solar neutrino ...
The Sanford Underground Research Facility (SURF), or Sanford Lab, is an underground laboratory in Lead, South Dakota. The deepest underground laboratory in the United States, it houses multiple experiments in areas such as dark matter and neutrino physics research, biology, geology and engineering. There are currently 28 active research ...
Neutrino experiments are scientific studies investigating the properties of neutrinos, which are subatomic particles that are very difficult to detect due to their weak interactions with matter. Neutrino experiments are essential for understanding the fundamental properties of matter and the universe's behaviour at the subatomic level.
The Sudbury Neutrino Observatory (SNO), a 2,100 m (6,900 ft) underground observatory in Sudbury, Canada, is the other site where neutrino oscillation research was taking place in the late 1990s and early 2000s. The results from experiments at this observatory along with those at Super-Kamiokande are what helped solve the solar neutrino problem.
The Homestake Mine is famous in scientific circles because of the work of a deep underground laboratory that was established there in the mid-1960s. This was the site where the solar neutrino problem was first discovered, in what is known as the Homestake Experiment.
Detailed observations of the neutrino spectrum from more advanced neutrino observatories produced results which no adjustment of the solar model could accommodate: while the overall lower neutrino flux (which the Homestake experiment results found) required a reduction in the solar core temperature, details in the energy spectrum of the ...
Within the Homestake Gold Mine in Lead, South Dakota, Davis placed a 380 cubic meter (100,000 gallon) tank of perchloroethylene 1,478 meters (4,850 feet) underground as a neutrino target. [22] The experiment would measure neutrino interactions with chlorine , since perchloroethylene is a common dry-cleaning fluid rich in that element.
τ), to which Homestake detector was insensitive. This explained the deficit in the results of the Homestake experiment. The final confirmation of this solution to the solar neutrino problem was provided in April 2002 by the SNO (Sudbury Neutrino Observatory) collaboration, which measured both ν e flux and the total neutrino flux.
