The X-ray crystal orienter​ operates based on the principle of X-ray diffraction. The high voltage generated by the high-voltage transformer acts on the X-ray tube, producing X-rays. When the X-ray is irradiated onto the sample, diffraction occurs when the Bragg diffraction condition (n λ=2dsin θ) is satisfied. Among them, λ is the wavelength of X-rays, d is the spacing between atomic planes inside the crystal, and θ is the angle between the incident X-rays and the crystal plane. The diffraction line is received by the counting tube and displayed on the microampere meter of the amplifier.
