Neutrinos
7 questions tagged Neutrinos — spanning every one of the seven Ws.
Where is the world's largest neutrino detector?
One of the largest neutrino detectors is Super-Kamiokande in Japan, under Mount Ikeno in Gifu Prefecture. It is a huge underground tank lined with thousands of sensors.
Where is the OPERA experiment that detected neutrinos from CERN located?
OPERA was located deep underground at the Gran Sasso National Laboratory in Italy. It studied neutrinos sent from CERN over a distance of about 730 kilometers.
Where is the Sudbury Neutrino Observatory located?
It is located more than 2 kilometers underground in a nickel mine near Sudbury, Ontario, Canada. The underground setting helps block cosmic rays.
Where is the Deep Underground Neutrino Experiment (DUNE) being built?
DUNE is being built between Fermilab in Illinois and the Sanford Underground Research Facility in South Dakota. Its far detector will be deep underground in the former Homestake mine.
Where is the first neutrino detector used in the discovery of the neutrino flux from the Sun located?
The pioneering solar-neutrino work began at the Homestake mine in South Dakota, USA. Raymond Davis Jr. used a large chlorine detector there starting in 1967.
How do scientists use neutrinos to study the weak force?
They detect how rarely neutrinos interact and compare those interactions with weak-force predictions. Neutrinos are one of the best probes of the weak interaction because they only feel the weak force and gravity.
Which force is responsible for the existence of neutrinos in beta decay?
The weak nuclear force produces and interacts with neutrinos in beta decay. Neutrinos were proposed to conserve energy and momentum in radioactive processes.
