MicroBooNE, A Liquid Argon Time Projection Chamber (LArTPC) Neutrino Experiment  [PDF]
Teppei Katori
Physics , 2011, DOI: 10.1063/1.3661595
Abstract: Liquid Argon time projection chamber (LArTPC) is a promising detector technology for future neutrino experiments. MicroBooNE is an upcoming LArTPC neutrino experiment which will be located on-axis of Booster Neutrino Beam (BNB) at Fermilab, USA. The R&D efforts on this detection method and related neutrino interaction measurements are discussed.
LANNDD---A Massive Liquid Argon Detector for Proton Decay, Supernova and Solar Neutrino Studies, and a Neutrino Factory Detector  [PDF]
David B. Cline,Franco Sergiampietri,John G. Learned,Kirk McDonald
Physics , 2001, DOI: 10.1016/S0168-9002(03)00656-9
Abstract: We describe a possible Liquid Argon Neutrino and Nuclear Decay Detector (LANNDD) that consists of a 70kt magnetized liquid argon tracking detector. The detector is being designed for the Carlsbad Underground Laboratory.
Solar nuclear energy generation and the chlorine solar neutrino experiment  [PDF]
H. J. Haubold,A. M. Mathai
Physics , 1994, DOI: 10.1063/1.47009
Abstract: The study of solar neutrinos may provide important insights into the physics of the central region of the Sun. Four solar neutrino experiments have confirmed the solar neutrino problem but do not clearly indicate whether solar physics, nuclear physics, or neutrino physics have to be improved to solve it. Nonlinear relations among the different neutrino fluxes are imposed by two coupled systems of differential equations governing the internal structure and time evolution of the Sun. We assume that the results of the four neutrino experiments are correct and are concerned not with the discrepancy between the average rate and the predicted rate, but with a possible time dependence of the argon production rate as revealed in the Homestake experiment over a time period of 20 years. Based on the subtlety of the solar neutrino problem we review here quantitatively the physical laws employed for understanding the internal solar structure and conjecture that the interlink between specific nuclear reactions of the PPIII-branch of the proton-proton chain may allow the high-energy solar neutrino flux to vary over time.
Implementation of a local principal curves algorithm for neutrino interaction reconstruction in a liquid argon volume  [PDF]
J. J. Back,G. J. Barker,S. B. Boyd,J. Einbeck,M. Haigh,B. Morgan,B. Oakley,Y. A. Ramachers,D. Roythorne
Physics , 2013, DOI: 10.1140/epjc/s10052-014-2832-4
Abstract: A local principal curve algorithm has been implemented in three dimensions for automated track and shower reconstruction of neutrino interactions in a liquid argon time projection chamber. We present details of the algorithm and characterise its performance on simulated data sets.
Implications of the GALLEX Source Experiment for the Solar Neutrino Problem  [PDF]
Naoya Hata,Wick Haxton
Physics , 1995, DOI: 10.1016/0370-2693(95)00598-F
Abstract: We argue that, prior to the recent GALLEX $^{51}$Cr source experiment, the excited state contributions to the $^{71}$Ga capture cross section for $^{51}$Cr and $^7$Be neutrinos were poorly constrained, despite forward-angle (p,n) measurements. We describe the origin of the uncertainties and estimate their extent. We explore the implications of the source experiment for solar neutrino capture in light of these uncertainties. A reanalysis of the $^7$Be and $^8$B flux constraints and MSW solutions of the solar neutrino puzzle is presented.
Cosmogenesis Backgrounds, Experiment Depth and the Solar Neutrino TPC  [PDF]
G. Bonvicini,A. Schreiner
Physics , 2002, DOI: 10.1016/S0168-9002(02)01550-4
Abstract: A Time Projection Chamber (TPC) is one of the promising candidates to perform unique measurements in solar neutrino physics. Its features will enable it to work at depths of the order of 2000 mwe. This paper describes an estimation of the expected cosmogenic background at different depths including also the background due to fission activation of the TPC material above ground.
Critical review of the results of the Homestake solar neutrino experiment  [PDF]
Paolo Walter Cattaneo
Physics , 2002,
Abstract: The radiochemical experiment in the Homestake mine was designed to measure the solar neutrino flux through the detection of $^{37}Ar$ produced in the reaction $\nu_e + ^{37}Cl \longrightarrow e^-+^{37}Ar$. The comparison between this measurement and the theoretical predictions from solar models evidences a substantial disagreement. I reanalyzed the data evidencing a bias with high statistical significance and suggesting a new interpretation of the data.
Which solar neutrino experiment after KamLAND and Borexino?  [PDF]
Alessandro Strumia,Francesco Vissani
Physics , 2001, DOI: 10.1088/1126-6708/2001/11/048
Abstract: We estimate how well we will know the parameters of solar neutrino oscillations after KamLAND and Borexino. The expected error on Delta m^2 is few per-mille in the VO and QVO regions, few per-cent in the LMA region, and around 10% in the LOW region. The expected error on sin^2 2theta is around 5%. KamLAND and Borexino will tell unambiguously which specific new measurement, dedicated to pp solar neutrinos, is able to contribute to the determination of theta and perhaps of Delta m^2. The present data suggest as more likely outcomes: no measurement, or the total pp rate, or its day/night variation.
Results and perspectives of the solar neutrino experiment Borexino  [PDF]
G. Ranucci,Borexino Collaboration
Physics , 2008,
Abstract: Borexino is a massive, calorimetric, liquid scintillator detector aimed at the detection of low energy sub-MeV solar neutrinos, installed at the Gran Sasso Laboratory. After several years of construction, data taking started in May 2007, providing immediately incontrovertible evidence of the unprecedented radiopurity of the target mass, at the level required to ensure the successful detection of 7Be solar neutrinos, which was then announced in the 2007 summer. In this talk first the main technical characteristics of the detector will be highlighted, with special emphasis on the exceptional purity challenges successfully faced by the Collaboration, and afterwards the physics outputs reached so far will be carefully reported and illustrated, together with the perspectives for the future measurements that will complete the broad program of the experiment.
Neutrino Magnetic Moment Solution for the Solar Neutrino Problem and the SNO Experiment  [PDF]
Joao Pulido
Physics , 2000, DOI: 10.1016/S0920-5632(01)01414-1
Abstract: The motivations for the magnetic moment solution to the solar neutrino problem are briefly reviewed and the expected values for a number of observables to be measured by the SNO experiment are calculated assuming three different solar magnetic field profiles. The observables examined are the charged current event rate, the ratio of the neutral current to the charged current event rates and the charged current electron spectrum as well as their first and second moments. The dependence of results on the hep neutrino flux is also analysed and a comparison is made with the corresponding oscillation results.
