Description

Technical Field

[0001] The utility model relates to the technical field of X-ray scattering, in particular to the field of a fine-tuning X-ray small-angle scattering monitoring device. Background Art

[0002] X-rays are electromagnetic waves with very short wavelengths. They have unique physical properties. They have strong penetrability. X-rays have a short wavelength, so they have great energy and strong penetrability. They can penetrate samples and display the composition information of samples by different absorption degrees of X-rays at different positions. Ionization: When a substance is irradiated by X-rays, the electrons outside the nucleus can be separated from the atomic orbit and ionized. The amount of X-ray irradiation can be measured by the amount of ionized charge. Fluorescence: When it irradiates certain compounds such as phosphorus, barium platinum cyanide, cadmium zinc sulfide, calcium tungstate, etc., it can cause the substance to fluoresce (visible light or ultraviolet light). The intensity of the fluorescence is proportional to the amount of X-rays. Interference, diffraction, reflection, and refraction, these basic properties of visible light are also applicable to X-rays. Based on the physical properties of X-rays, the application research of X-rays has made great progress. In the medical field, the penetrability of X-rays is used as a means of diagnosing diseases. Its fluorescence effect can also be used to make a fluorescent screen, which is used to observe the image of X-rays passing through human tissues during fluoroscopy. It can also be made into an intensifying screen, which is used to enhance the photosensitivity of film during photography. In scientific research, it is used in X-ray microscopy, wavelength measurement and material structure analysis.

[0003] Small angle X-ray scattering is a scattering phenomenon that occurs when X-rays pass through a sample within a small angle range of 2° to 5° close to the original beam. Small angle X-ray scattering is used to analyze the structure of extremely large unit cell materials and to determine the size, shape and distribution of ultrafine powder particles (or ultrafine holes in solid materials) with a particle size of less than tens of nanometers. For polymer materials, it can measure the size and shape of polymer particles or voids, analyze the phase structure of blended polymers, analyze the long period, branching degree, molecular chain length, and measure the glass transition temperature.
