1. Analysis of Coincidence-Time Loopholes in Experimental Bell Tests
Emanuel H Knill, B. G. Christensen, A. Hill, Y. Zhang, Scott C Glancy, Kevin J Coakley, Lynden Krister Shalm, Sae Woo Nam, P. G. Kwiat
We apply a distance-based Bell-test analysis method ["Bell inequalities for continuously emitting sources" E. Knill et al. arXiv:14097732 (2014)] to three experimental data sets where conventional analyses failed or required additional assumptions. T ...
2. Update on the MiniCLEAN Dark Matter Experiment
Kevin J Coakley, K. Rielage, M. Akashi-Ronquest, M. Bodmer, R. Bourque, B. Buck, A. Butcher, T. Caldwell, Y. Chen, F. A. Duncan, E. Flores, J. A. Formaggio, D. Glaster, F. Giuliani, M. Gold, E.

McFarlane, D. N. McKinsey, S. MacMullin, A. Mastbaum, D.-M. Mei, J. Monroe, J. A. Nikkel, J. Oertel, G. D. Orebi Gann, K. Palladino, G. Perumpilly, L. Rodriguez, R. Schnee, S. Seibert, J. Walding, B. Wang, J. Wang, C. Zhang
The direct search for dark matter is entering a period of increased sensitivity to the hypothetical Weakly Interacting Massive Particle (WIMP). One such technology that is being examined is a scintillationonly noble liquid experiment, MiniCLEAN. Mi ...
3. Bell Inequalities for Continuously Emitting Sources
Emanuel H Knill, Scott C Glancy, Sae Woo Nam, Kevin J Coakley, Yanbao Zhang
A common experimental strategy for demonstrating non-classical correlations is to show violation of a Bell inequality by measuring a continuously emitted stream of entangled photon pairs. The measurements involve the detection of photons by two spat ...
4. Improving Photoelectron Counting and Particle Identification in Scintillation Detectors with Bayesian Techniques
Kevin J Coakley, M. Akashi-Ronquest, P.-A. Amaudruz, B. Beltran, M. Bodmer, M.G. Boulay, R. Bourque, B. Buck, A. Butcher, B. Cai, T. Caldwell, M. Chen, Y. Chen, B. Cleveland, F. A. Duncan, E.

Perumpilly, T. Pollmann, W. Rau, F. Reti'ere, L. Rodriguez, R. Schnee, S. Seibert, P. Skensved, T. Sonley, E. V'azquez Ja' uregui, J. Walding, B. Wang
Many current and future dark matter and neutrino detectors are designed to record scintillation light with a large array of photomultiplier tubes (PMTs). The energy resolution and particle identification capabilities of these detectors depend in part ...
5. Adaptive and Robust Statistical Methods for Processing Near-Field Scanning Microwave Microscopy Images
Kevin J Coakley, Samuel Berweger, Atif A. Imtiaz, Thomas M Wallis, Joel C Weber, Pavel Kabos
Near-field scanning microwave microscopy offers great potential to facilitate characterization, development and modeling of materials. By acquiring microwave images at multiple frequencies and amplitudes (along with the other modalities) one can stud ...
6. Nonproportionality in the scintillation light yield of bismuth germanate
Thomas R Gentile, M J Bales, H Breuer, T E. Chupp, Kevin J Coakley, R L Cooper, Jeffrey S Nico, Brian O'Neill
We present measurements of nonproportionality in the scintillation light yield of bismuth germanate (BGO) for gamma-rays with energies between 6 keV and 662 keV. The scintillation light was read out by avalanche photodiodes (APDs) with both the BGO c ...
7. Detection of Hazardous Liquids using Microwave
Michael D Janezic, Jolene D Splett, Kevin J Coakley, James R. Baker-Jarvis
The primary objective of this study is to determine the feasibility of using low-power microwaves to distinguish between hazardous and non-hazardous liquids at security checkpoints.
According to the 2008 High-Priority Technology Needs, a report publi ...
8. Stochastic Modeling and Simulation of Marginally Trapped Neutrons
Kevin J Coakley
For a magnetic trapping experiment, I present an efficient method for simulating experimental beta−decay rates which accounts for loss of marginally trapped neutrons due to wall collisions and other possible loss mechanisms. Monte Carlo estima ...
9. Gallium Nitride Nanowire Probe for Near-Field Scanning Microwave Microscopy
Joel C Weber, Paul Timothy Blanchard, Aric Warner Sanders, Atif A. Imtiaz, Thomas M Wallis, Kevin J Coakley, Kristine A Bertness, Pavel Kabos, Norman A Sanford, Victor M. Bright
We report on the fabrication of a GaN nanowire probe for near-field scanning microwave microscopy.
A single nanowire was Pt-bonded to a commercial Si cantilever prior to evaporation of a Ti/Al
coating to provide a microwave signal pathway. Test ...
10. Neutron Tomography of a Fuel Cell: Statistical Learning Implementation of a Penalized Likelihood
Kevin J Coakley, Dominic F. (Dominic F.) Vecchia, Daniel S Hussey, David L Jacobson
At the NIST Neutron Imaging Facility, we collect neutron projection data for both the dry and wet
states of a Proton-Exchange-Membrane (PEM) fuel cell. Transmitted neutrons captured in a
scintillator doped with Lithium-6 produce scintillation li ...
