Neurychlovačová astročásticová fyzika v podzemní laboratoři LSM (Francie)

AbstraktAbstract

Cílem projektu je pokračování a postupné rozšiřování dlouhodobé vědecké spolupráce mezi českým řešitelským týmem a podzemní laboratoří LSM spolu s dalšími zahraničními institucemi a týmy, které v LSM realizují svoje projekty z oblasti základního výzkumu a rozvíjejí související technologie (neutrinová fyzika, měření velmi nízkých aktivit, studium vlivu ionizujícího záření na živé organismy). Konkrétní cíle stanovené na období řešení projektu: 1) Dokončení publikací s výsledky experimentu NEMO 3 (poločasy rozpadu dvojného rozpadu beta pro izotopy 100Mo, 82Se, 96Zr, 116Cd, 130Te a 48Ca). 2) Dlouhodobé studium dvojného elektronového záchytu na jádře 106Cd v rámci experimentů TGV a SPT. 3) Uvedení do provozu prvního modulu experimentu SuperNEMO (bezneutrinový dvojný rozpad beta). 4) Rozvoj technologií pro nízké radioaktivní pozadí (nízkopozaďový HPGe detektor, monitorování radonu na úrovni mBq/m3). 5) Zapojení dalšího českého pracoviště (ÚJF AV ČR) do aktivit v LSM (radiobiologie).

The aim of the project is a continuation and gradual expansion of long-term scientific cooperation between the Czech team and underground laboratory LSM along with other foreign institutions and teams cooperating with LSM, which realize their projects in the field of basic research and develop related technologies (neutrino physics, measurements of very low activities, study of the effects of ionizing radiation on cells, etc.). The specific objectives of the project : 1 ) Completion of publications with the results of the experiment NEMO 3 (half-lives of double beta decay of isotopes 100Mo, 82Se, 96Zr, 116Cd, 130Te and 48Ca). 2 ) Long-term study of double electron capture the nucleus 106Cd in the experiments TGV and SPT. 3 ) Commissioning of the first module of the experiment SuperNEMO (neutrinoless double beta decay). 4 ) Development of technologies for low radioactive background (ultra-low background HPGe detector, monitoring of radon on level mBq/m3). 5 ) Involvement of another Czech institution (NPI ASCR) into the activities of LSM (radiobiology).
