“…36 The three crystal plates have to be parallel to high accuracy 89 and the whole device needs to be protected from vibrations in order to observe interference. 91 A monoenergetic neutron beam is split by the splitter plate (BS0). Neutrons refracted by beam splitters BS1 and BS2 (mirror plate) are directed to the analyzer plate (BS3), also acting as a BS, thereby first passing through a rotatable-plate phase shifter (e. g. aluminum foil 36 ).…”

We review an event-based simulation approach which reproduces the statistical distributions of wave theory not by requiring the knowledge of the solution of the wave equation of the whole system but by generating detection events oneby-one according to an unknown distribution. We illustrate its applicability to various single photon and single neutron interferometry experiments and to two Bell-test experiments, a single-photon Einstein-Podolsky-Rosen experiment employing post-selection for photon pair identification and a single-neutron Bell test interferometry experiment with nearly 100% detection efficiency.

Off-diagonal geometric phases acquired in the evolution of a spin-1/2 system have been investigated by means of a polarized neutron interferometer. Final counts with and without polarization analysis enable us to observe simultaneously the off-diagonal and diagonal geometric phases in two detectors. We have quantitatively measured the off-diagonal geometric phase for noncyclic evolutions, confirming the theoretical predictions. We discuss the significance of our experiment in terms of geometric phases (both diagonal and off-diagonal) and in terms of the quantum erasing phenomenon.

“…The pinhole system was the collimator instrument (V4) 27) of the Hahn-Meitner Institut (HMI), Berlin, Germany, while the DC systems were the high resolution double bentcrystal instrument (DN-2) 24) of the Nuclear Physics Institute (NPI), Rez, Czech Republic, and the ultra high resolution Bonse-Hart instrument (S18) 28) of the Institut Laue-Langevin (ILL), Grenoble, France. Figure 2(a) shows a schematic view of the collimator SANS instrument, which is equipped with a two-dimensional 3 He-detector with 64 × 64 elements of 10 × 10 mm 2 .…”

Characterization of Cavities in Superplastically Deformed Tetragonal Zirconia Polycrystals by Means of Small Angle Neutron Scattering

Small angle neutron scattering (SANS) method was applied to investigate morphology of cavities in superplastically deformed 3 mol% yttria stabilized tetragonal zirconia polycrystals (3Y-TZP). The 3Y-TZP specimens were deformed in tension at 1723 K with an initial strain rate of 3.3 × 10 −4 s −1 in the air to pre-determined nominal strains ranging from 0.0 to 200%. Three kinds of SANS instruments having individually different scattering vector ranges were used. Results obtained from a pinhole SANS instrument revealed that initially fine and equi-axed cavities evolved, with the progress of the deformation, into the anisotropic ones with their longest diameters parallel to the tensile direction. Results obtained from a double bent-crystal and a Bonse-Hart SANS instruments showed that the average radius of all cavities existing in the specimens decreased initially with increasing nominal strain, but subsequently this trend was reversed when the nominal strain exceeded about 100%. Specific surface of cavities began to increase at a nominal strain of approximately 20%. Size distributions obtained from the SANS data showed that highest peaks appeared at a cavity radius of around 200 nm for each of the specimens deformed to different strains, which indicated that the cavities with radius of around 200 nm accounted for the largest in number among all the cavities existed.
