76. Improved TPB-coated Light Guides for Liquid Argon TPC Light Detection Systems: Air Measurements

Mr Alexander Moss (MIT)

09/06/2015, 13:15

This talk will discuss the outcome of recent research and development of wavelength-shifting lightguides for LArTPCs. The response of the lightguides was characterized in both air and liquid argon. Attenuation lengths over 100cm were consistently measured in air, which is an important step in the development of meter-scale lightguides for future LArTPCs. Additionally, good agreement was found...

73. Characterization of New Meter Scale Light Guides for Liquid Argon TPC Light Collection

Mr Jarrett Moon (MIT)

The ability to detect 128 nm scintillation light from liquid argon (LAr) is of critical importance in current and future liquid argon time-projection chamber (LarTPC) experiments. To this end, tetraphenyl butadiene (TPB) has been employed in light collection systems to shift 128 nm light to visible wavelengths. Work has been done recently using TPB in conjunction with light guides to improve...

30. Dirt Neutrons in MicroBooNE

Katherine Woodruff (New Mexico State University)

The MicroBooNE detector will allow a measurement of neutral-current elastic interactions at an unprecedented low momentum transfer. The most problematic background to these low Q^2 interactions are from neutrons produced by interactions in the dirt surrounding MicroBooNE. A scintillator detector just upstream of MicroBooNE could provide us with a clean sample of dirt neutron events in...

88. Searches for neutron-antineutron oscillations with Liquid Argon TPC experiments

Mr Jeremy Hewes (The University of Manchester)

09/06/2015, 14:00

Neutron to antineutron (nnbar) oscillation is a baryon number violating process, predicted by several classes of Grand Unified Theories. The planned Deep Underground Neutrino Experiment (DUNE) will utilise an underground 40kt Liquid Argon time projection chamber (LArTPC), uniquely equipped to carry out a low-background search for such oscillations of neutrons bound in the argon nucleus. There...

40. Searching for dark sector phenomena at LArTPC fixed target experiments

Ms Brooke Russell (Yale University)

09/06/2015, 14:15

A significant region of parameter space for weakly interacting massive particle dark matter has been ruled out by direct detection experiments. New models have suggested extensions to the Standard Model, known as dark sectors, proposing sub-GeV dark matter candidates which could have eluded most direct detection experiments. In this talk, I will discuss searches for evidence of these dark...

39. LArIAT - Liquid Argon In A Testbeam

Elena Gramellini (Yale University)

09/06/2015, 14:30

The Liquid Argon Time Projection Chamber (LArTPC) represents one of the most advanced experimental technologies for physics at the Intensity Frontier due to its full 3D-imaging, excellent particle identification (PID) and precise calorimetric energy reconstruction. By deploying LArTPCs in a dedicated calibration test beam line at Fermilab, the LArIAT program aims to experimentally...

54. Scintillation light detection in the LArIAT TPC

Pawel Kryczynski (Fermilab/INP PAS Krakow)

09/06/2015, 14:45

LArIAT is a Liquid Argon TPC currently taking data at Fermilab with the aim of calibrating the argon response for neutrino detectors. In parallel, it will help develop and evaluate the performance of the simulation, analysis and reconstruction software, used in other LAr neutrino experiments. LArIAT is running on a test beam of charged particles (mainly protons, pions and muons), ...
