Orientation of Vortices in a Superconducting Thin-Film: Quantitative Comparison of Spin-Polarized Neutron Reflectivity and Magnetization
S. -W. Han, J. Farmer, H. Kaiser +3
We present a quantitative comparison of the magnetization measured by spin-polarized neutron reflectivity (SPNR) and DC magnetometry on a 1370 Ã -thick Nb superconducting film. As…
Scheduling optimization of parallel linear algebra algorithms using Supervised Learning
G. Laberge, S. Shirzad, P. Diehl +3
Linear algebra algorithms are used widely in a variety of domains, e.g machine learning, numerical physics and video games graphics. For all these applications, loop-level parallel…
Neutronic Design and Measured Performance of the Low Energy Neutron Source (LENS) Target Moderator Reflector Assembly
C. M. Lavelle, D. V. Baxter, A. Bogdanov +12
The Low Energy Neutron Source (LENS) is an accelerator-based pulsed cold neutron facility under construction at the Indiana University Cyclotron Facility (IUCF). The idea behind LE…
Precision neutron interferometric measurements and updated evaluations of the n-p and n-d coherent neutron scattering lengths
K. Schoen, D. L. Jacobson, M. Arif +6
We have performed high-precision measurements of the coherent neutron scattering lengths of gas phase molecular hydrogen and deuterium using neutron interferometry. After correctin…
Measuring the Neutron's Mean Square Charge Radius Using Neutron Interferometry
F. E. Wietfeldt, M. Huber, T. C. Black +4
The neutron is electrically neutral, but its substructure consists of charged quarks so it may have an internal charge distribution. In fact it is known to have a negative mean squ…
Precision neutron interferometric measurement of the nd coherent neutron scattering length and consequences for models of three-nucleon forces
T. C. Black, P. R. Huffman, D. L. Jacobson +6
We have performed the first high precision measurement of the coherent neutron scattering length of deuterium in a pure sample using neutron interferometry. We find b_nd = (6.665 +…
