The rotating sample holder in an X-ray diffractometer is a key component used for precise adjustment and fixation of the sample position,the sample can rotate within its own plane, which is beneficial for errors caused by coarse grains. For samples with texture and crystallography, rotating sample holder ensures good reproducibility of diffraction intensity and eliminates preferred orientation. Working principle of rotating sample holder: When the X-ray diffractometer is working, high-energy X-rays generated by the X-ray source are irradiated onto the sample fixed on the rotating sample stage. Due to the specific crystal structure and lattice parameters of the sample, X-rays will undergo scattering, absorption, and diffraction phenomena when interacting with the sample, where diffraction phenomena occur according to the requirements of the Bragg equation. The rotating sample holder can rotate at smaller angles according to the setting, allowing the sample to receive X-ray irradiation at different angles, thereby obtaining diffraction patterns at different angles. In this way, the detector can measure the X-ray intensity after sample diffraction and convert it into an electrical signal to be transmitted to the computer for data processing.
