FE.00001: The MINERvA Neutrino Scattering Experiment Ronald Ransome MINERvA part 1. MINERvA is a neutrino scattering experiment in the NuMI beamline at Fermilab. MINERvA began taking data in November, 2009. The detector is fully active and includes targets of helium, carbon, iron, and water upstream of the active region. We will describe the detector and its capabilities, including tracking resolution, energy resolution, and particle identification, and brief overview of physics objectives. [Preview Abstract] |

FE.00002: Anti-Neutrino Quasi-Elastic Scattering at MINERvA Emily Maher Quasi-elastic neutrino scattering provides a means of measuring the axial form factor of the nucleon, and is a valuable tool for determining the neutrino beam energy in oscillation experiments. There are disagreements between measurements for neutrino energies below 1 GeV on scintillator and those at higher energies. MINERvA provides a bridge between the two regimes. Preliminary results for charge current quasi-elastic scattering results for anti-neutrinos ($\bar{\nu}_{\mu} + p \rightarrow \mu^+ + n$) on scintillator will be presented. [Preview Abstract] |

FE.00003: Neutrino Exclusive Charged Current Quasi-Elastic Scattering in MINERvA Tammy Walton MINERvA part 3. The MINERvA experiment will measure neutrino and antineutrino quasi-elastic scattering on helium, water, carbon, iron, and lead for neutrinos in the few GeV range. We will present an overview and status of the analysis for neutrino exclusive charged current quasi-elastic scattering on lead, iron, and carbon. [Preview Abstract] |

FE.00004: Inclusive Neutrino Cross Section Measurements at MINERvA Brian Tice MINERvA part 4. The knowledge of inclusive neutrino cross sections is valuable for neutrino oscillation experiments. Determination of the A dependence of the cross section can help determine the role of nuclear effects in neutrino scattering, which is poorly known and difficult to model. Preliminary ratios of cross sections on carbon, iron and lead will be shown. [Preview Abstract] |
Thursday, October 25, 2012 4:48PM - 5:00PM |
FE.00005: Neutrino induced pion production at MINERvA Trung Le MINERvA part 5. Pion production with neutrinos can proceed through several means, including resonances, deep inelastic scattering, or coherent scattering. Determination of the cross section and understanding of the reaction requires good identification of both charged and neutral pions. Studies of pion production in MINERvA will be presented.

FE.00006: Performance of the LENS Detector Architecture Bertis Rasco The Low-Energy Neutrino Spectroscopy (LENS) experiment will precisely measure the energy spectrum of low-energy solar neutrinos via charged-current neutrino reactions on indium. The LENS detector concept applies indium-loaded scintillator in an optically-segmented lattice geometry to achieve precise time and spatial resolution with unprecedented sensitivity for low-energy neutrino events. The LENS collaboration is currently developing prototypes at the Kimballton Underground Research Facility (KURF) that aim to demonstrate the performance and selectivity of the scintillation lattice technology. Benchmarking of the prototypes with Monte Carlo simulations is an important step towards understanding the as-built detector performance and implementing the full LENS. We will present an overview of the LENS experiment, general results of Monte Carlo simulations, and the comparison of measurements with the LENS prototypes to the Monte Carlo simulations. [Preview Abstract] |

FE.00007: Testing the LENS Scintillation Lattice with MicroLENS Liudmyla Afanasieva The LENS Collaboration is developing a next-generation instrument to precisely measure the full spectrum of solar neutrinos, including low energy neutrinos from hydrogen fusion (pp-neutrinos). Detection lies in charged-current capture of neutrinos on 115In in metal-loaded scintillator. The detector architecture employs a lattice structure with a low index of refraction immersed into scintillator to provide precise time and spatial resolution to distinguish the neutrino signal from background. A first generation prototype, microLENS, has been constructed and is currently operating. Measurements with microLENS test the basic optical properties of the lattice detector architecture that is fundamental to the approach. Results from measurements with the microLENS prototype will be discussed. [Preview Abstract] |

FE.00008: Low Radioactivity Film Light Guides for Large Neutrino Detectors Zachary Yokley Light guides having ultra-low radioactivity, high-efficiency, and low cost are being developed to solve light collection in large neutrino experiments requiring extensive shielding between fiducial volumes and photomultiplier tubes (PMTs) and other external backgrounds. Such guides are particularly useful when segmentation of the detector is possible. The Low Energy Neutrino Spectrometer (LENS) detector uses an optically segmented 3D lattice that channels light via total internal reflection from an internal scintillation event down channels parallel to the 3 primary Cartesian axes to the edge of the detector. This unprecedented spatial resolution allows the LENS experiment to measure the solar neutrino spectrum above $\sim $115 keV in the presence of its background In decay. Retaining the channel information prohibits use of traditional non-imaging light collectors. Thus, the LENS collaboration has developed guides made from multilayer films, providing both total internal and specular reflections. This talk will present the design and construction of these novel film guides in the context of LENS, and the construction of a 400 liter prototype miniLENS. [Preview Abstract] |
