Testing the Leggett-Garg inequality with solar neutrinos
… measurement outcomes. The flavor oscillations of solar neutrinos provide an interesting way to test the Leggett-Garg inequality, and on an astrophysical length scale. Beginning as electron neutrinos in the solar core, they undergo the Mikheyev-Smirnov-Wolfenstein Effect and exit the sun in either …

Feasibility Analysis and Prototype Measurements of a Novel Approach for the Real-Time Spectroscopy of Low Energy Solar Neutrinos
… aims at the real-time spectroscopy of low energy solar neutrinos. Detection would proceed via inverse-EC to an isomeric state. The coincidence of prompt electron and delayed nuclear de-excitation gives a specific signature for background suppression. The most promising targets are Yb-176 and …

PURIFICATION AND CHARACTERIZATION OF THE JUNO LIQUID SCINTILLATOR: FIRST RADIOPURITY RESULTS
… scintil- lator experiment devoted to study neutrinos. JUNO (Jiangmen Underground Neutrino Observatory) is the largest organic liquid scintillator detector ever built. It exploits 20000 tons of organic liquid scintillator contained in a huge Acrylic Vessel (d = 35 m), detecting neutrinos and …

An Analysis of the 3-He Proportional Counter Data from the Sudbury Neutrino Observatory Using Pulse Shape Discrimination
… by the neutral current interaction of 8-B solar neutrinos with deuterium. Previously published results from this phase were based on a spectral analysis of the energy deposited in the proportional counters. The work in this thesis introduces a new observable based on the time-profile of the …

Science and Technology of a Low-Energy Solar Neutrino Spectrometer (LENS) and Development of the MiniLENS Underground Prototype
… real time low energy spectral measurement of the neutrinos coming from the Sun will give us a greater understanding of energy production in the Sun, and the mechanisms of neutrino mixing. We will, for the first time, measure the solar neutrino spectrum for all solar neutrinos <2MeV in particular …

Direct and Indirect Searches for Anomalous Beta Decay
… of several isotopes may have been influenced by solar activity (perhaps by solar neutrinos). A mechanism in which (anti)neutrinos can influence the decay process suggests that a sample of decaying nuclei emitting neutrinos could affect its own rate of decay. Past experiments have searched for …

Aging tests for dielectric-coated aluminum to be used in the Sudbury Neutrino Observatory
… heavy water Cerenkov detector designed to detect solar neutrinos. Its main objective is to confirm or negate the solar neutrino problem. To achieve maximum counting rates and, thus, minimum statistical uncertainties, collection of Cerenkov light must be maximized. Our group at UBC, working with …

Internal Radioactive Source Calibration of the Borexino Solar Neutrino Experiment
A measurement of solar neutrinos below 1 MeV of energy will further our knowledge of the neutrino's mass and mixing properties and will provide a probe to possible physics beyond the standard model of particle physics, as well as advance our understanding of energy production in the Sun. Borexino …

Neutrino capital of the world
Neutrinos are ubiquitous particles, but they don't like to mingle. Each second, billions of them pass through our bodies, slicing imperceptibly through our delicate internal organs. They can barrel through the sun, stars, and planets without a single interaction. Only one in every ten billion of …

The Development of the SNO+ Experiment: Scintillator Timing, Pulse Shape Discrimination, and Sterile Neutrinos
… double beta decay, and will measure low energy solar neutrinos. This thesis will describe three main development activities for the SNO+ experiment: the measurement of the timing parameters for the liquid scintillator cocktail, using those timing parameters to estimate the ability of SNO+ to …

Reactor Antineutrinos In The Sno+ Water Phase And Detector R&d For Large-Scale Neutrino Detectors
… detector using a 190.3 day dataset. Reactor neutrinos have never before been detected in a water Cherenkov detector, primarily due to the difficulty in detecting the low energy signal from neutron captures on free protons. However, enormous effort towards driving the trigger threshold to an …

Neutrino Oscillations: Eighty Years In Review
