“…Reactor neutrino experiments played an important role in neutrino physics since the first experimental observation of antineutrinos by Reines and Cowan et al [1]. In 2012 Daya Bay experiment observed non-zero neutrino mixing angle θ 13 with a significance more than 5 σ [2], consistent with recent measurements from other experiments [3][4][5][6].…”

Abstract. The Daya Bay Reactor Neutrino Experiment uses an array of eight underground detectors to study antineutrinos from six reactor cores with different baselines. Since the start of data-taking from late 2011, Daya Bay has collected the largest sample of reactor antineutrino events to date, and has made the most precise measurement of the neutrino oscillation parameters sin 2 2θ 13 and ∆m 2 ee . Using the data from the four detectors in the near experimental halls, Daya Bay has made a high statistics measurement of the absolute reactor antineutrino flux and spectrum. In this paper we will present this measurement and its comparison to predictions based on different flux models.

“…Three years later, Enrico Fermi named this particle the neutrino (v). It wasn't until 1956 where Frederick Reines and Clyde Cowon found the first experimental evidence for the electron (anti-) neutrino using a large 400 L water and cadmium chloride (Cd0 2 ) detector 12 m underground [18). In this experiment, Reines and Cowon looked at the inverse ,B-decay (v+p ..... n+e+) and measured the gamma ray photons produced from positrons annihilating with electrons using photomultiplier tubes.…”

We certify that we have read this thesis and that, in our opinion, it is satisfactory in scope and quality as a thesis for the degree of Master of Science in Physics. at SLAC (Stanford Linear Accelerator Center), radio Cherenkov detection techniques are possible in the ultra-high energy regime (10 18 -+ 1022 eV) while observing electromagnetic cascades in dielectric media. This method of detection has now moved into the field of neutrino astrophysics. Recently, the interest in using ice as a dielectric medium to observe coherent microwave Cherenkov pulses from ultra-high energy neutrino induced particle showers has grown considerably with advances from experiments such as RICE, FORTE, and ANITA-lite. ANITA (ANtarctic Impulsive Transient Antenna), is a radio telescope designed to exploit this effect while looking for UHE neutrino interactions in Antarctic ice.In June 2006, ANITA observed these highly coherent radio impulses in SLAC's ESA (End Station A) with 28.5 GeV electrons interacting with a 7.5 tonne ice target to produce the EM shower. These first measurements of the Askaryan effect in ice were consistent with shower and electrodynamics simulations for ice and provided a clear indication that the radiation is coherent over the 200-1200 MHz frequency window. In addition to the ANITA payload in SLAC's ESA, four log-period dipole array antennas, two monocone antennas, and one high frequency gain hom (nominally 2.6-3.95 GHz) recorded impulsive events emanating from the ice target. I report on further analysis of coherent radio Cherenkov impulses using the standard gain hom and demonstrate that the results are fully consistent with theoretical expectations.vii

“…As early as 1932 Enrico Fermi provided a theoretical framework for β-decay which included the neutrino but it took another 25 years before the neutrino was detected experimentally. In 1957 Frederick Reines and Clyde Cowan made the first observation of the free antineutrino through the inverse β-reaction ν e + p → e + + n utilizing the flux of ν from the Savannah River nuclear reactor 1 . The muon neutrino was finally detected by Schwartz, Lederman, and Steinberger in 1961…”

Neutrino mass and mixing are amongst the major discoveries of recent years. From the observation of flavor change in solar and atmospheric neutrino experiments to the measurements of neutrino mixing with terrestrial neutrinos, recent experiments have provided consistent and compelling evidence for the mixing of massive neutrinos. The discoveries at Super-Kamiokande, SNO, and KamLAND have solved the long-standing solar neutrino problem and demand that we make the first significant revision of the Standard Model in decades. Searches for neutrinoless double-beta decay probe the particle nature of neutrinos and continue to place limits on the effective mass of the neutrino. Possible signs of neutrinoless double-beta decay will stimulate neutrino mass searches in the next decade and beyond. I review the recent discoveries in neutrino physics and the current evidence for massive neutrinos. Neutrinos Within the Standard ModelIn 1930 Pauli postulated the neutrino as a "desperate remedy" to the energy crisis of the time -the continuous energy spectrum of electrons emitted in nuclear β-decay. With the postulate of a new particle Pauli could account for the continuous spectrum. He assumed that nuclear β-decay emits a neutron together with an electron in such a way that the sum of the energies is constant. Sensitive measurements of the energy and momentum of β-decay electrons and the recoiling nuclei in cloud chambers indicated that substantial quantities of energy and momentum were missing. These experiments left little doubt that a third particle had to be involved. As early as 1932 Enrico Fermi provided a theoretical framework for β-decay which
