Increased interference fringe visibility from the post-fabrication heat treatment of a perfect crystal silicon neutron interferometer

Heacock, Benjamin; Arif, Muhammad; Cory, David G.; Gnaeupel-Herold, Thomas; Haun, Robert; Huber, Michael G.; Jamer, Michelle E.; Nsofini, Joachim; Pushin, Dimitry A.; Sarenac, Dusan; Taminiau, Ivan; Young, Albert R. (AIP Publishing, 2018-02-08)

We find that annealing a previously chemically etched interferometer at 800 degrees C dramatically increased the interference fringe visibility from 23% to 90%. The Bragg plane misalignments were also measured before and ...
Three Phase-Grating Moire Neutron Interferometer for Large Interferometer Area Applications

Sarenac, Dusan; Pushin, Dimitry A.; Huber, Michael G.; Hussey, Daniel S.; Miao, Haixing; Arif, Muhammad; Cory, David G.; Cronin, Alex D.; Heacock, Benjamin; Jacobson, David L.; LaManna, Jacob M.; Wen, Han (American Physical Society, 2018-03-12)

We demonstrate a three phase-grating moire neutron interferometer in a highly intense neutron beam as a robust candidate for large area interferometry applications and for the characterization of materials. This novel ...
