A possibility of parallel and anti-parallel diffraction measurements on neutron diffractometer employing bent perfect crystal monochromator at the monochromatic focusing condition

Original language description

In a conventional diffractometer having single monochromator, only one position, parallel position, is used for the diffraction experiment (i.e. detection) because the resolution property of the other one, anti-parallel position, is very poor. However, abent perfect crystal (BPC) monochromator at monochromatic focusing condition can provide a quite flat and equal resolution property at both parallel and anti-parallel positions and thus one can have a chance to use both sides for the diffraction experiment. From the data of the FWHM and the Deltad/d measured on three diffraction geometries (symmetric, asymmetric compression and asymmetric expansion), we can conclude that the simultaneous diffraction measurement in both parallel and anti-parallel positions can be achieved.

Možnosti měření paralelní a antiparalelní difrakce neutronovými difraktometry s ohnutým perfektním krystalem jako monochromátorem a monochromatickou fokusační podmínkou

Czech description

V konvenčních difraktometrech s jednoduchým monochrámoterm je užívána pouze paralelní pozice v difrakčních experimentech protože rozlišení v antiparalelní pozici je velmi nízké. Monochromátory s perfektním ohnutým krystalem splňující monochromatickou fokusační podmínku poskytují relativně široké a stejné rozlišovací vlastnosti v obou pozicích.
