The Neutrino Ettore Majorana Observatory (NEMO experiment) is an international collaboration of scientists searching for neutrinoless double beta decay (0νββ). The collaboration has been active since 1989. Observation of 0νββ would indicate neutrinos are Majorana particles and could be used to measure the neutrino mass. It is located in the Modane Underground Laboratory (LSM) in the Fréjus Road Tunnel. The experiment has (as of 2018) had 3 detectors, NEMO-1, NEMO-2, NEMO-3 (and a demonstrator module of SuperNEMO-detector) and is planning (as of 2018) to construct a new detector SuperNEMO. The NEMO-1 and NEMO-2 prototype detectors were used until 1997. Latest experiment NEMO-3 was under design and construction from 1994 onwards, took data from January 2003 to January 2011 and the final data

- The Neutrino Ettore Majorana Observatory (NEMO experiment) is an international collaboration of scientists searching for neutrinoless double beta decay (0νββ). The collaboration has been active since 1989. Observation of 0νββ would indicate neutrinos are Majorana particles and could be used to measure the neutrino mass. It is located in the Modane Underground Laboratory (LSM) in the Fréjus Road Tunnel. The experiment has (as of 2018) had 3 detectors, NEMO-1, NEMO-2, NEMO-3 (and a demonstrator module of SuperNEMO-detector) and is planning (as of 2018) to construct a new detector SuperNEMO. The NEMO-1 and NEMO-2 prototype detectors were used until 1997. Latest experiment NEMO-3 was under design and construction from 1994 onwards, took data from January 2003 to January 2011 and the final data analysis was published in 2018. The NEMO-2 and NEMO-3 detectors produced measurements for double neutrino decays and limits for neutrinoless double-beta decay for a number of elements, such as molybdenum-100 and selenium-82. These double beta decay times are important contributions to understanding the nucleus and are needed inputs for neutrinoless decay studies, which constrain neutrino mass. The NEMO collaboration remains active and is constructing an improved SuperNEMO detector. Planning of SuperNEMO and commissioning of SuperNEMO demonstrator module is on-going as of 2019. (en)
- L'expérience NEMO (Neutrino Ettore Majorana Observatory) résulte d'une collaboration internationale scientifique, on peut citer en France: le CENBG (Centre d'Études Nucléaires de Bordeaux-Gradignan), l'IN2P3 du CNRS ou encore le LAL (Laboratoire de l'Accélérateur Linéaire), au Royaume-Uni l'université de Manchester. La collaboration recherche les désintégrations double bêta sans émission de neutrinos. L'observation de telles désintégrations indiquerait que le neutrino est une particule de Majorana, et pourrait être utilisée pour mesurer la masse des neutrinos. En réalité, on ne peut remonter qu'à la masse effective du neutrino, ce qui donne déjà une bonne idée de sa masse intrinsèque. L'expérience NEMO3 s'est déroulée dans le Laboratoire souterrain de Modane (LSM) dans le tunnel routier du Fréjus sur 7 ans, la prise de données commençant en janvier 2003 pour s'arrêter le 18 janvier 2011, après avoir permis de déterminer une masse maximale du neutrino inférieure à 1 eV. Le détecteur ne permettant pas de descendre plus bas, son démontage doit être suivi du projet Super-Nemo, toujours en cours de mise en œuvre mi-2016. (fr)
