Neutron multiple reflections excited in cylindrically bent perfect crystals and their possible use for high-resolution neutron scattering

Result description

In the paper there are presented results of studie sof multiple reflections observed in elastically bent perfect crystals of Si. Feasibility of neutron diffractometer equipped with a high-resolution multiple-reflection monochromator was tested for noncoventional radiography experiments. Multiple-reflection monochromator extracts a highly monochromatic and highly collimated neutron beam from the polychromatic one. Excellent parameters of the monochromatic beam then permit one to use it for some special radiography experiments. Moreover, a highly monochromatic beam provides the possibility of imaging by means of phase contrast radiography.

    Vícenásobné reflexe neutronů buzené v cylindricky ohnutých dokonalých monokrystalech a jejich možné využití pro metody neutronového rozptylu s vysokým rozlišením

  • Czech description

    V článku jsou presentovány výsledky studia vícenásobných reflexí pozorovaných v elasticky ohnutých křemíkových destičkách. Dále je diskutovaná možnost využití neutronového difraktometru vybaveného monochromátorem na bázi vícenásobných reflexí k nekonvenčním experimentům v oblasti neutronové radiografie. Monochromátor na bázi vícenásobných reflexí poskytuje vysoce monochromatický svazek, který je současně vysoce kolimovaný a tím dovoluje jeho využití ve vybraných radiografických experimentech. Vysoká kolimace neutronového svazku umožňuje dokonce experimenty v oblasti radiografie na bázi fázového kontrastu.
