Xenon NMR Measurements of Permeability and Tortuosity in Reservoir Rocks
R. Wang, T. Pavlin, M. S. Rosen +3
In this work we present measurements of permeability, effective porosity and tortuosity on a variety of rock samples using NMR/MRI of thermal and laser-polarized gas. Permeability…
Study of Gas-Fluidization Dynamics with Laser-Polarized 129Xe
R. Wang, M. S. Rosen, D. Candela +2
We report initial NMR studies of gas dynamics in a particle bed fluidized by laser-polarized xenon (129Xe) gas. We have made preliminary measurements of two important characteristi…
3He Lung Imaging in an Open Access, Very-Low-Field Human MRI System
R. W. Mair, M. I. Hrovat, S. Patz +7
The human lung and its functions are extremely sensitive to gravity, however the conventional high-field magnets used for most laser-polarized 3He MRI of the human lung restrict su…
Tortuosity Measurement and the Effects of Finite Pulse Widths on Xenon Gas Diffusion NMR Studies of Porous Media
R. W. Mair, M. D. Hurlimann, P. N. Sen +3
We have extended the utility of NMR as a technique to probe porous media structure over length scales of ~ 100 - 2000 micron by using the spin 1/2 noble gas 129Xe imbibed into the…
Applications of controlled-flow laser-polarized xenon gas to porous and granular media study
R. W. Mair, R. Wang, M. S. Rosen +3
We report initial NMR studies of continuous flow laser-polarized xenon gas, both in unrestricted tubing, and in a model porous media. The study uses Pulsed Gradient Spin Echo-based…
New Clock Comparison Tests of Lorentz Symmetry
Ronald L. Walsworth, David F. Phillips
We present two new measurements constraining Lorentz and CPT violation using the Xe-129 / He-3 Zeeman maser and atomic hydrogen masers. Experimental investigations of Lorentz and C…
