JF¡ª3 X-ray crystal Analytical instrument:
Laue camera and high precision definite direction
Purpose:
Take pictures:utilize back shoot Lao E method to take pictures.
The film is installed between the crystal and the radial source.
the incidence beams pass through the eyelet on the film.
Record for backward diffraction beams,use the diffraction
beam direction to measure the unknown shape and size of
the crystal cell and to measure the crystal tropism and to
assess the perfect crystal.
Definite direction:carry on the precision to measure the angle
and definite direction to the crystal material. Use x-ray to
pass the prepositive monochrome machine,the diffraction
beam is monochromatized and then irradiate on the sample.
accord with the formula:n¦Ë=2dsin¦Èdiffraction and received by count tube to enlarge.show the strength by the meter and read the accurate angle value by the clinometer.
