Characterization of a Nd-loaded organic liquid scintillator for neutrinoless double beta decay search of Nd with a 10-ton scale detector
نویسندگان
چکیده
Several liters of an organic liquid scintillator (LS) loaded with Nd have been made. We report on performances of this scintillator in terms of optical properties, radiopurity and light yield for a Nd concentration of 6.5 g/l. A possible application to search for the Nd neutrinoless double beta (0νββ) decay with a 10-ton scale LS detector is discussed together with further improvements.

Neutrinoless double beta decay with SNO+
SNO+ will search for neutrinoless double beta decay by loading 780 tonnes of linear alkylbenzene liquid scintillator with O(tonne) of neodymium. Using natural Nd at 0.1% loading will provide 43.7 kg of Nd given its 5.6% abundance and allow the experiment to reach a sensitivity to the effective neutrino mass of 100-200 meV at 90% C.L in a 3 year run. The SNO+ detector has ultra low backgrounds w...

The third and final phase of the Sudbury Neutrino Observatory (SNO) experiment utilized a series of He proportional counters called Neutral Current Detectors (NCDs) to detect the neutrons produced by the neutral current interactions of solar neutrinos in the detector. The number of neutrons detected by the NCDs, and hence the total flux of B solar neutrinos, has been determined using two novel ...

The ongoing search for neutrinoless double beta decay is one of the most active fields in particle physics today. Neutrinoless double beta decay, if observed, will provide insight into physics beyond the standard model. Improving scintillator composition in order to optimize light yield and eliminate background is one way to increase detector sensitivity. This paper presents studies on the ligh...

EXO is a search for neutrinoless double beta decay in 136 Xe. An active R&D program for a 10 ton, enriched 136 Xe liquid phase detector is now underway. Current research projects are: decay product extraction, Xe purity studies, energy resolution studies, and Ba+ ion laser-tagging. Half lives of up to 5.0x10 28 yr will be ultimately probed, corresponding to a sensitivity to Majorana neutrino ma...

The NEMO-3 detector, which has been operating in the Fréjus Underground Laboratory since February 2003, is devoted to searching for neutrinoless double beta decay (ββ0ν). The expected performance of the detector has been successfully achieved. Half-lives of the two neutrinos double beta decay (ββ2ν) have been measured for 150 Nd. After 265 days of data collection from February 2003 until March ...
