In Situ Cosmogenic Backgrounds In The Majorana Demonstrator, Andrew Lopez
In Situ Cosmogenic Backgrounds In The Majorana Demonstrator, Andrew Lopez
Doctoral Dissertations
Neutrino-less double-beta decay is a proposed type of radioactive decay that, if observed, could answer several outstanding physics questions, such as "Is the neutrino its own antiparticle otherwise known as a Majorana particle?", "What is the mass of the neutrino?", and "What is the neutrino mass hierarchy?" As technology and experimental techniques improve, the sensitivity of experiments looking for rare events becomes more dependent on the backgrounds. Some of these backgrounds can be reduced using shielding techniques such as implementing a veto system, selecting radiopure components, and conducting the experiment deep underground. However some amount of cosmogenically induced backgrounds remain …

Neutrinoless double-β decay (0νββ) searches typically involve large-scale experiments for which backgrounds can be complex. One possible source of background near the 0νββ signature in the observed spectra is γ rays arising from inelastic neutron scattering from the materials composing or surrounding the detector. In relation to searches for the 0νββ of 136Xe to 136Ba, such as the EXO-200 and KamLAND-Zen projects, inelastic neutron scattering γ-ray production cross sections for 136Xe and 134Xe are of importance for characterizing such γ rays that may inhibit the unambiguous identification of this yet-to-be-observed …

We report the final result of the CUORICINO experiment. Operated between 2003 and 2008, with a total exposure of 19.75 kg · y of 130Te, CUORICINO was able to set a lower bound on the 130Te 0vββ half-life of 2.8 x 1024 years at 90% C.L. The limit here reported includes the effects of systematic uncertainties that are examined in detail in the paper. The corresponding upper bound on the neutrino Majorana mass is in the range 300–710 meV, depending on the adopted nuclear matrix element evaluation.

We present a search for β+/EC double beta decay of 120Te performed with the CUORICINO experiment, an array of TeO2 cryogenic bolometers. After collecting 0.0573 kg · y of 120Te, we see no evidence of a signal and therefore set the following limits on the half-life: T0v 1/2 > 1.9 · 1021 y at 90% C.L. for the 0v mode and T2v1/2 > 7.6 · 1019 y at 90% C.L. for the 2v mode. These results improve the existing limits by almost three orders of magnitude (four in the case of 0v mode).

To better understand the contribution of cosmic ray muons to the CUORICINO background, 10 plastic scintillator detectors were installed at the CUORICINO site and operated during the final 3 months of the experiment. From these measurements, an upper limit of 0.0021 counts/(keV kg yr) (95% CL) was obtained on the cosmic ray-induced background in the neutrinoless double beta decay region of interest. The measurements were also compared to GEANT4 simulations.

The main purpose of the Cryogenic Underground Observatory for Rare Events (CUORE) experiment is the search for the Neutrinoless Double Beta Decay (0νDBD) of n130Te reaching a sensitivity on Majorana mass better than 50 meV. Cuoricino represents not only the first stage of CUORE, but also the most massive 0νDBD experiment presently running. Present results and future planning of these experiments will be described in the paper.

A novel technique has been developed to build vessels for liquid xenon ionization detectors entirely out of an ultra-clean fluoropolymer. One such detector was operated inside a welded, He leak tight, all-fluoropolymer chamber. The measured energy resolution for 570 keV gamma rays is σ/E=5.1% at a drift field of 1.5 kV/cm, in line with the best values obtained for ionization only detectors run in LXe using conventional, metal vessels.

After an introduction on the various experimental techniques to be adopted in searches for double beta decay, the new approach based on the use of cryogenic low temperature detectors is described. The present results are reported on the limit for neutrinoless double beta decay of n130Te obtained with the large bolometric detector CUORICINO. This setup consists of 44 cubic crystals of natural TeOn2 with 5 cm sides and 18 crystals of 3 × 3 × 6 cmn3. Four of these latter crystals are made with isotopically enriched materials: two in n128Te and two …

Nuclear matrix elements (M_{GT}) for two-neutrino double beta transitions of selected nuclei were calculated via a QRPA approach by considering the charge-exchange spin-spin interactions in the particle-hole channel among nucleons. Calculations were performed for both spherical and deformed cases of nuclei. As a result of these calculations, it has been seen that, although the value of the nuclear matrix elements in deformation case are 2-4 times smaller when compared with that of the spherical case, it is still 2-8 times greater than the experimental values.
