Transmission crystals (Le Cauchois)
Transmission crystals have been invented and used by Yvette Le Cauchois, a French Physicist.
In a transmission crystal configuration, the lattice planes are orientated perpendicularly to the surface of a crystal plate, so that the X rays are diffracting along their path through the crystal thickness.
They can be tilted from the perpendicular to enlarge the spectra.
It allows to use uncollimated X Ray beam and get better spectrum in a lower time of exposure of the sample than the conventional X Ray spectroscopy at this time.
AlpyX applies very rigorous preparation of the geometry of the crystal plate in order to master stringent parameters.
Once produced and controlled, the crystal plate is curved onto a holder having an opened window in its center to allow the monochromatized X ray to reach the detector.
