M17.00001: A First Search for a Low Energy Excess in MicroBooNE David Kaleko MicroBooNE is a neutrino experiment which began taking Booster Neutrino Beam data at Fermilab in October 2015. It employs an 89 ton (active volume) liquid argon Time Projection Chamber (TPC) to record ionization signals from particles produced in neutrino interactions and uses scintillation light detected by a PMT array to provide precise interaction timing information. The flagship physics measurement for which the MicroBooNE experiment was designed is the investigation of the excess of electromagnetic events observed by MiniBooNE. This talk will discuss initial analysis techniques aimed at confirming and understanding the source of this ``low energy excess", including event selection, neutrino energy reconstruction, and various techniques for mitigating expected backgrounds that will affect this analysis.

M17.00002: Prospects for the neutral current single $\pi^{0}$ cross section with the MicroBooNE detector Ryan Grosso MicroBooNE is an 89 ton active volume liquid argon TPC that has been collecting neutrino data in the Booster Neutrino Beamline at Fermilab since October 2015. The experiment is designed to study the low energy excess of electromagnetic events observed by MiniBooNE and to measure a large suite of cross sections in argon with an average neutrino energy of about 800 MeV. A measurement of the neutral current single $\pi^{0}$ cross section in argon is particularly valuable as it forms an important background for $\nu_{e}$ appearance searches at MicroBooNE and other liquid argon based experiments. This talk will present some of the challenges associated with identifying and reconstructing neutral current $\pi^{0}$ interactions in MicroBooNE and discuss prospects for upcoming cross section measurements of this channel.

M17.00003: Reconstructing Michel Electrons in the MicroBooNE Detector David Caratelli MicroBooNE is a Liquid Argon Time Projection Chamber (LArTPC) neutrino detector located in the Booster Neutrino Beamline at Fermilab which began collecting neutrino data in October 2015. MicroBooNE aims to explore the low-energy excess in the $\nu_e$ spectrum reported by MiniBooNE as well as perform $\nu$-Ar cross-section measurements. In this talk, we present the current status of reconstructing Michel electrons from cosmic ray muons in the MicroBooNE detector. These Michel electrons are distributed uniformly inside the detector, and serve as a natural and powerful calibration source to study the detector's response for low energy (10s of MeV) interactions as a function of position. We have developed a reconstruction software tool to successfully identify such Michel electrons which could be of benefit to LArTPC experiments generically. [Preview Abstract] |

M17.00004: Monitoring Liquid Argon Time Projection Chambers With A Raspberry Pi Camera Crystal Patteson The MicroBooNE detector is the first of three liquid argon (LAr) time projection chambers (TPCs) that are central to the short-baseline neutrino program at Fermilab. These chambers consist of thousands of stainless steel or beryllium-copper sense wires that detect ionization electrons produced when neutrinos interact with liquid argon nuclei inside the detector. The wires are several hundred microns in diameter to several meters in length. The construction of such LAr TPCs often takes place in an assembly hall, which is different from the detector hall where the experiment will operate, as was the case with MicroBooNE. Since in situ access to the chamber and its wires in the beamline enclosure can be limited, we investigate the possibility of using a Raspberry Pi single-board computer connected to a low-cost camera installed inside the cryostat as a cost-efficient way to verify the integrity of the wires after transport. We also highlight other benefits of this monitoring device implemented in MicroBooNE, including detector hall surveillance and verification of the status of LED indicators on detector electronics.

M17.00005: Overview of the CAPTAIN program Qiuguang Liu Liquid argon time projection chamber detectors are taking center stage for the next large projects that the high-energy physics society will pursue. A series of tens of kiloton liquid argon detectors are under development to be used to measure the neutrino oscillation parameters, the CP violation in the neutrino sector, and the neutrino mass hierarchy, while also for the opportunity to the search for proton decay and supernova measurement as part of the DUNE program. ~However, several smaller liquid argon detectors are needed to study cross-sections and perform studies at various energies. ~The CAPTAIN Collaboration is building a 10-ton liquid argon detector as well as a prototype detector to perform measurements that include neutron interactions in liquid argon using the beam at LANSCE and neutrino measurements using the beam at Fermilab. The prototype experiment, MiniCAPTAIN, has been commissioned and is successfully running with laser operations, cosmic rays, and recently with neutrons from LANSCE. ~I will present an overview and status of the CAPTAIN program.

M17.00006: The CAPTAIN-MINERvA Experiment Jieun Yoo The CAPTAIN-MINERvA experiment aims to measure neutrino-argon interactions in the few GeV energy range, which corresponds to the first oscillation maximum for DUNE. It uses the CAPTAIN LArTPC as an active target in conjunction with MINERvA to measure the neutrino interactions and will provide the only high-statistics measurement of the neutrino-argon cross section above 2 GeV before DUNE. CAPTAIN is a liquid argon TPC which is currently being built at LANL. It will be moved to Fermilab and be used in conjunction with MINERvA. Using MINERvA as the tracking detector will allow us to measure the muon energy by dE/dx and thus more completely measure the incoming neutrino energy. And, by measuring the ratio of cross sections in argon to hydrocarbon in the scintillator, we will be able to make stringent tests of nuclear effect models. Thus, through this unique combination of detectors, CAPTAIN-MINERvA will be able to study neutrino-argon interactions and serve as an important source of input for DUNE. [Preview Abstract] |
