This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrinoless double beta decay (0[nu][beta][beta]) is a rare second-order process that, if observed, would confirm that neutrinos are Majorana fermions. This process violates the conservation of lepton number and hence would provide yet another indication of physics beyond the Standard Model (SM). EXO-200 was an experiment aiming to detect 0[nu][beta][beta], and nEXO is the next generation experiment proposed as a successor to EXO-200 using enriched 136Xe in a time projection chamber. It is projected that nEXO will reach a sensitivity of 1.35×1028yr to the 0[nu][beta][beta] half life of 136Xe with 10 years of data taking. nEXO uses silicon photomultipliers (SiPMs) for light detection. Calibration of SiPMs is very important to meet the energy resolution requirement of

Basharina-Freshville and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's most precise half-life measurement of T 2nu_1/2 = [7.02 ± 0.01(stat) ± 0.46(syst)] × 10 18 years has been made for the 2\nu\beta\beta decay of 100Mo using data from 6.9kg collected with the NEMO3 detector over 1471 days. The 2\nu nuclear matrix element has been extracted using T 2nu_1/2 and is M 2\nu = 0.126 ± 0.004. The 0\nu\beta\beta search yielded a limit on the half-life of T 0\nu_1/2 1/1 > 1.1 × 10 24 years at the 90% CL, corresponding to a limit on the effective Majorona mass of \langle M\nu e\rangle
Download or read book Towards a Precise Energy Calibration of the CUORE Double Beta Decay Experiment written by and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mass of the neutrino may hold the key to many problems in cosmology and astrophysics. The observation of neutrino oscillations shows that neutrinos have mass, which was something that was not accounted for in the Standard Model of particle physics. This thesis covers topics relating to measuring the value of neutrino mass directly using bolometers. The first section will discuss the neutrino mass and different experiments for measuring the mass using bolometers. The mass of the neutrino can be measured directly from -decay or inferred from observation of neutrinoless double beta decay (0). In this work I present Monte Carlo and analytic simulation of the MARE experiment including, pile-up and energy resolution effects. The mass measurement limits of a micro-calorimeter experiments as it relates to the quantity of decays measured is provided. A similar simulation is preformed for the HolMES experiment. The motivation is to determine the sensitivity of such experiments and the detector requirements to reach the goal sensitivity. Another possible method for determining the neutrino mass is to use neutrinoless double beta decay. The second section will cover the Cryogenic Underground Observatory for Rare Events (CUORE) detector calibration system (DCS). CUORE is a neutrinoless double beta decay (0) experiment with an active mass of 206 kg of 130Te. The detector consists of 988 TeO2 bolometers operating at 10 mK. The signature of 0 decay is an excess of events at the Q-value of 2528 keV. Understanding the energy response is critical for event identification, but this presents many challenges. Calibration is necessary to associate a known energy from a with a voltage pulse from the detector. The DCS must overcome many design challenges. The calibration source must be placed safely and reliable within the detector. The temperature of the detector region of the cryostat must not be changed during calibration. To achieve this calibration sources must be cooled before before introducing them to the detector region. The highest acceptable temperature of the calibration sources are estimated using the Stephan-Boltzmann Law. The ability to cool the calibration sources to these temperatures was measured in several tests. The first test established the force required to cool the calibration sources within the time allotted. The second test established the time frame required for cooling the calibration sources to the required temperature. A model for ensuring the calibration sources are below the required temperature and recommended procedure for cooling the calibration sources is provided.

This book was released on 2014 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using the NEMO-3 detector, 410.4 g of 116Cd with a total exposure of 1.65 kg· y and 932 g of 82Se with a total exposure of 3.75 kg· y were used to measure the half-life of two-neutrino double beta decay (2[nu][beta][beta]) to the ground states of 116Sn and 82Kr and to place a lower limit on the neutrinoless double becay decay (0[nu][beta][beta]) to the same ground states. Under the single-states dominance hypothesis, the 2[nu][beta][beta] half-lives are found to be T 1/2(116Cd) = (2.90 ± 0.03(stat) ± 0.15(syst)×1019 yr and T 1/2(82Se) = [10.62±0.11(stat)±0.56(syst)]×1019 yr. 0[nu][beta][beta] is excluded to 90% confidence level at T 1/2 ≥ 1.12 × 1023 yr for 116Cd and T 1/2 ≥ 3.90 × 1023 yr for 82Se. These half-lives correspond to effective Majorana neutrino masses of m ≤ (4.33 - 5.54) eV and m ≤ (2.28 - 2.82) eV, respectively, in the light Majorana exchange mechanism.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The SuperNEMO experiment will search for the neutrinoless double beta decay of 82Se, with an expected half-life sensitivity of >10^26 years. The first stage of the experiment, the SuperNEMO Demonstrator Module, is expected to achieve a half-life sensitivity of 6.6×10^24 years after running for 2.5 years with 7 kg of source isotope. Key results from the construction, and commissioning of the wire tracker for the Demonstrator Module are described, and the drift distance-time relationship of each of the first three quarters measured. The two-neutrino double-beta decay half-life of 100Mo has been measured as 7.01±0.01(stat)±0.46\(syst)×10^18 years using a sample of 6914 g of isotope measured for 5.25 years by the precursor experiment, NEMO-3. The summed electron energy spectrum was unfolded, allowing for a limit of -1.12×10^-1
