The graphite element is mounted on a perfect Si single crystal 1 mm thick to minimize any phonon scattering, while the highly perfect extinction-limited crystal essentially eliminates
Bragg scattering from the mount.
Another recipient, Professor Tai-Wen Hsu, with research foci on wave turbulence model,
Bragg scattering of water waves, numerical simulation of near-shore hydrodynamics, WWM wave model, two-phase flow, RANS turbulence model, and management of coastal environment.
Short wavelength neutrons can be filtered from the beam using
Bragg scattering from polycrystalline materials, the most common being beryllium.
The successful observation of the clear Bragg scattering pattern from the single crystal converter and the reasonable results from the first experimental trial of the ultracold neutron production with the single crystal are shown.
The present study reports on the results of our preliminary experiments of the orthodeuterium single crystal preparation as the UCN converter and its Bragg scattering observed, and further the first trial of UCN production with the single crystal of orthodeuterium.

Bragg scattering on a CoFe crystal with known analyzing power.
In the configuration where P [perpendicular to] [tau], half the magnetic
Bragg scattering involves a reversal of the neutron spin (denoted by the (- +) configuration), and half does not, and for a purely magnetic reflection the spin-flip (- +) and non-spinflip (+ +) intensities should then be equal in intensity.
