Abstract: In one aspect, the invention is an improved pulsed-neutron monochromator of the vibrated-crystal type. The monochromator is designed to provide neutron pulses which are characterized both by short duration and high density. A row of neutron-reflecting crystals is disposed in a neutron beam to reflect neutrons onto a common target. The crystals in the row define progressively larger neutron-scattering angles and are vibrated sequentially in descending order with respect to the size of their scattering angles, thus generating neutron pulses which arrive simultaneously at the target. Transducers are coupled to one end of the crystals to vibrate them in an essentially non-resonant mode. The transducers propagate transverse waves in the crystal which progress longitudinally therein. The wave are absorbed at the undriven ends of the crystals by damping material mounted thereon. In another aspect, the invention is a method for generating neutron pulses characterized by high intensity and short duration.

Abstract: Neutron optics based on the two-reflection geometries are capable of controlling beams of long wavelength neutrons with low angular divergence. The preferred mirror fabrication technique is a replication process with electroform nickel replication process being preferable. In the preliminary demonstration test an electroform nickel optics gave the neutron current density gain at the focal spot of the mirror at least 8 for neutron wavelengths in the range from 6 to 20 Å. The replication techniques can be also be used to fabricate neutron beam controlling guides.

Abstract: The subject of the invention is a procedure for manufacturing a neutron-guiding flat surface of low waviness in the course of which a thin plate coated by a material suitable for neutron reflection, advantageously of multilayered structure, is glued onto a significantly thicker carrier surface. The procedure is characterised by placing the thin neutron-reflecting plate onto a base surface of low flatness, typically of the order of magnitude of 10−5 radian, advantageously onto a vacuum table, so that the thin plate lies on the base surface with the neutron-reflecting coating facing the base surface, then the thin plate is positioned on the base surface by means of applying reclining contact points formed along the base edge determined by the size of the thin plate, the thin plate is fixed onto the base surface by means of vacuum suction, then the reclining contacts are removed and a glue is attached to the upper surface of the fixed thin plate which displays low absorption capacity to neutrons and retains its binding strength in the presence of incident neutrons, then the thick carrier plate is stuck to the upper surface of the thin plate by moving the thick plate back and forth thus providing the homogeneous dispersion of the glue, then the thick carrier plate is fixed onto the base surface by reclining points and the binding process of the glue is accelerated by a known and appropriately selected procedure of binding acceleration, then finally the glued plates are removed from the base surface by undoing the reclining points.

Abstract: A polarized neutron guide for separating neutrons into polarized neutrons while minimizing loss of the neutrons is provided. The polarized neutron guide includes a body, the first space and the second space, and a neutron separation space. The body includes super mirrors coated with a neutron-reflective thin film and the first and second spaces are formed by the first plate inside the body. The neutron separation space is formed by the second plate disposed at the entry of the first space and the third plate disposed at the entry of the second space. Spin-up polarized neutrons and spin-down polarized neutrons are simultaneously separated and transferred in the first and second spaces, respectively. Therefore, with minimum loss of the neutrons, the spin-up polarized neutrons and the spin-down polarized neutrons are effectively separated and collected.
