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