Neutrino Ettore Majorana Observatory

from Wikipedia, the free encyclopedia

The Neutrino Ettore Majorana Observatory (NEMO) is an international physical experiment (under French management) with the purpose of investigating the double beta decay of molybdenum -100 and thus indirectly the properties of neutrinos . It is named after Ettore Majorana .

NEMO 1 and 2

After the start of the NEMO collaboration, two prototype detectors, NEMO 1 and NEMO2, were built from 1989 and operated until 1997.

NEMO 3

Since 2003, NEMO 3 has been used to search for the neutrino-free double beta decay that has never been observed . The measurements ended in 2011. A follow-up experiment, SuperNEMO, is in preparation.

The observation of neutrino double beta decay would fundamental insights into the absolute mass and the matter / antimatter - Symmetry supply of neutrinos. The most important discovery would be the decision as to whether neutrinos are Dirac or marjoram particles .

The experiment is located in the Fréjus Underground Laboratory (LSM) in Modane ( Savoie , France ).

Note and individual evidence

  1. Despite the designation Observatory , NEMO is not one of the facilities mentioned under Neutrino Observatory , because no neutrinos from distant sources are observed.
