A Model for the Global Quantum Efficiency for a TPB-based Wavelength-Shifting System used with Photomultiplier Tubes in Liquid Argon in MicroBooNE
S. F. Pate, T. Wester, L. Bugel +7
We present a model for the Global Quantum Efficiency (GQE) of the MicroBooNE optical units. An optical unit consists of a flat, circular acrylic plate, coated with tetraphenyl buta…
Summary of the Second Workshop on Liquid Argon Time Projection Chamber Research and Development in the United States
R. Acciarri, M. Adamowski, D. Artrip +41
The second workshop to discuss the development of liquid argon time projection chambers (LArTPCs) in the United States was held at Fermilab on July 8-9, 2014. The workshop was orga…
Improved TPB-coated Light Guides for Liquid Argon TPC Light Detection Systems
Z. Moss, L. Bugel, G. Collin +5
Scintillation light produced in liquid argon (LAr) must be shifted from 128 nm to visible wavelengths in light detection systems used for liquid argon time-projection chambers (LAr…
Breakdown voltage of metal-oxide resistors in liquid argon
L. F. Bagby, S. Gollapinni, C. C. James +10
We characterized a sample of metal-oxide resistors and measured their breakdown voltage in liquid argon by applying high voltage (HV) pulses over a 3 second period. This test mimic…
A Simulation of the Optical Attenuation of TPB Coated Light-guide Detectors
B. J. P. Jones
This note describes simple simulations which were performed in order to understand the attenuation behaviors of acrylic light-guides operated in air and argon, which were character…
TPB-coated Light Guides for Liquid Argon TPC Light Detection Systems
C. M. Ignarra
Light detection systems in Liquid Argon Time Projection Chambers (LArTPCs) require the detection of the 128 nm light produced during argon scintillation. Most detectors use Tetraph…
A Measurement of the Absorption of Liquid Argon Scintillation Light by Dissolved Nitrogen at the Part-Per-Million Level
B. J. P. Jones, C. S. Chiu, J. M. Conrad +3
We report on a measurement of the absorption length of scintillation light in liquid argon due to dissolved nitrogen at the part-per-million (ppm) level. We inject controlled quant…
Testing of Cryogenic Photomultiplier Tubes for the MicroBooNE Experiment
T. Briese, L. Bugel, J. M. Conrad +13
The MicroBooNE detector, to be located on axis in the Booster Neutrino Beamline (BNB) at the Fermi National Accelerator Laboratory (Fermilab), consists of two main components: a la…
Photodegradation Mechanisms of Tetraphenyl Butadiene Coatings for Liquid Argon Detectors
B. J. P. Jones, J. K. VanGemert, J. M. Conrad +1
We report on studies of degradation mechanisms of tetraphenyl butadiene (TPB) coatings of the type used in neutrino and dark matter liquid argon experiments. Using gas chromatograp…
Benchmarking TPB-coated Light Guides for Liquid Argon TPC Light Detection Systems
B. Baptista, L. Bugel, C. Chiu +5
Scintillation light from liquid argon is produced at 128 nm and thus must be shifted to visible wavelengths in light detection systems used for Liquid Argon Time Projection Chamber…
Environmental Effects on TPB Wavelength-Shifting Coatings
C. S. Chiu, C. Ignarra, L. Bugel +5
The scintillation detection systems of liquid argon time projection chambers (LArTPCs) require wavelength shifters to detect the 128 nm scintillation light produced in liquid argon…
Demonstration of a Lightguide Detector for Liquid Argon TPCs
L. Bugel, J. M. Conrad, C. Ignarra +4
We report demonstration of light detection in liquid argon using an acrylic lightguide detector system. This opens the opportunity for development of an inexpensive, large-area lig…
