Special corrugated ceramic tubes, metal ceramic tubes, and glass tubes for analytical instruments, suitable for various models of XRD, XRF, crystal analyzers, and orientation instruments at home and abroad. An X-ray tube is a vacuum electronic device that generates X-rays by high-speed electron impact on a metal target material. Its structure, principle, and application involve various technical characteristics. 1. Basic structure of X-ray tube (1) Cathode (electron emission source) Composed of tungsten filament, X-ray tube heats up and emits electrons after being powered on, and is wrapped around a focusing cover (cathode head) to control the direction of the electron beam. The filament temperature is about 2000K, and the electron emission is regulated by current. (2) Anode (target material) Usually high melting point metals (such as tungsten, molybdenum, rhodium, etc.) are used to withstand high-energy electron bombardment and generate X-rays. Contains anode head (target surface), anode cap, glass ring, and anode handle, responsible for heat dissipation (through radiation or conduction) and absorption of secondary electrons. (3) Vacuum shell and window Glass or ceramic shell maintains a high vacuum environment (not less than 10 ⁻⁴ Pa) to avoid electron scattering. Window materials require low X-ray absorption, commonly using beryllium sheets, aluminum, or Lindemann glass. 2. Working principle of X-ray tube (1) Electron Acceleration and Impact The electrons emitted by the cathode filament are accelerated by high voltage (in the range of kilovolts to megavolts) and collide with the anode target material. The process of converting electronic kinetic energy into X-rays includes: Bremsstrahlung: Continuous spectrum X-rays released when electrons decelerate or deflect. Characteristic radiation: X-rays (such as Kα and Kβ lines) released by electron transitions in the inner layer of the target material. (2) Energy Conversion and Efficiency Only about 1% of the electron energy is converted into X-rays, and the remaining is dissipated in the form of heat, requiring forced cooling (such as a rotating anode design). 3. Classification and application scenarios of X-ray tubes (1) By generating electronic means Inflatable tube: an early type that relies on gas ionization to generate electrons, with low power and short lifespan (now obsolete). Vacuum tube: Modern mainstream, high vacuum environment improves electronic efficiency and stability. (2) By purpose In the medical field, diagnostic (such as dental and breast examinations) and therapeutic (such as radiotherapy) X-ray tube often use rotating anodes to increase power density. Industrial testing: non-destructive testing, material structure analysis, etc., with a focus on high penetration (hard X-rays). (3) According to the cooling method Fixed anode: simple structure, suitable for low-power scenarios. Rotating anode: The target surface rotates at high speed (up to 10000 revolutions per minute) to improve heat dissipation and support high-power output. 4. Performance characteristics and limitations of X-ray tubes (1) Advantages Low cost, small size, easy operation, suitable for routine medical and industrial testing. Flexible adjustment of target materials (such as tungsten, molybdenum, copper) to meet different energy requirements. (2) Limitations Poor brightness and collimation, large X-ray divergence angle, requiring additional collimators. The energy spectrum is continuous and contains characteristic lines, requiring filtering or monochromatization (such as using nickel filters to remove Kβ lines). 5. Comparison between X-ray tubes and synchrotron radiation sources (1) Brightness and flux X-ray tube: Low brightness, suitable for routine testing. Synchrotron radiation light source: with a brightness 106~1012times higher, suitable for cutting-edge research such as nanoimaging and protein crystallography. (2) Spectral characteristics X-ray tube: Discrete characteristic lines+continuous spectrum, energy range limited by acceleration voltage. Synchrotron radiation: wide continuous spectrum (from infrared to hard X-rays), precisely tunable. (3) Time characteristics X-ray tube: Continuous or microsecond level pulses (rotating target). Synchrotron radiation: Femtosecond level pulses, suitable for studying dynamic processes such as chemical reactions. 6. Technical parameters of X-ray tube (1) Optional target material types: Cu, Co, Fe, Cr, Mo, Ti, W, etc (2) Focus type: 0.2 × 12mm2 or 1 × 10mm2 or 0.4 × 14mm2 (fine focus) (3) Larger output power: 2.4kW or 2.7kW Overall, X-ray tube dominate in fields such as medical diagnosis and industrial testing due to their practicality and economy, but are limited by performance bottlenecks. For scenes that require high resolution and high brightness (such as cutting-edge scientific research), advanced technologies such as synchrotron radiation sources need to be relied upon. Future development directions include improving energy conversion efficiency, optimizing heat dissipation structures, and developing miniaturized X-ray sources.

X-ray absorption fine structure spectrometer (XAFS)​ is a powerful tool for studying the local atomic or electronic structure of materials, widely used in popular fields such as catalysis, energy, and nanotechnology. The basic principle of X-ray absorption fine structure spectrometer (XAFS) is that when the energy of X-rays resonates with the energy of an inner electron shell of an element in the sample, a sudden increase in electrons is excited to form a continuous spectrum, which is called the absorption edge. Near the absorption edge, as the X-ray energy increases, the absorption rate monotonically decreases as the penetration depth of the X-ray increases. When the spectrum is extended beyond a specific edge, fine structures can be observed, where X-ray absorption near edge structures (XANES) regions appear as soon as peaks and shoulders with a width exceeding 20 to 30 electron volts pass through the starting point of the edge. The fine structure located on the high-energy side of the edge where energy decays to several hundred electron volts is called X-ray Absorption Fine Structure (XAFS).

Strong elemental characteristics: The X-ray absorption edge has elemental characteristics, and for atoms of different elements in the sample, the atomic neighbor structure of different elements in the same compound can be studied by adjusting the incident X-ray energy. High sensitivity: Fluorescence method can be used to measure samples of elements with concentrations as low as one millionth. Comprehensive acquisition of structural information: able to provide parameters that determine the local structure, such as the distance between absorbing atoms and neighboring atoms, the number and type of these atoms, and the oxidation state of absorbing elements. Sample preparation is simple: no single crystal is required, and under the experimental conditions, the data collection time is relatively short. Using a synchrotron X-ray source usually only takes a few minutes to measure a spectral line. The main advantages of X-ray absorption fine structure spectrometer (XAFS) are: Core advantage: highest luminous flux product Photon flux exceeding 1000000 photons/second/eV, with spectral efficiency several times higher than other products; Obtain data quality equivalent to synchrotron radiation Excellent stability: The stability of monochromatic light intensity of the light source is better than 0.1%, and the energy drift during repeated collection is less than 50 meV 1% detection limit: High luminous flux, excellent optical path optimization, and excellent light source stability ensure that high-quality EXAFS data can still be obtained when the measured element content is>1%. 4. Application areas of X-ray absorption fine structure spectrometer (XAFS) : Energy field: such as research on lithium batteries and other secondary battery materials, fuel cell research, hydrogen storage material research, etc. XAFS can be used to obtain the concentration, valence state, coordination environment, and dynamic changes of core atoms during charge discharge cycles and electrochemical reactions. Catalysis field: used for research on nanoparticle catalysis, single atom catalysis, etc. Obtain the morphology of the catalyst on the support, the interaction form with the support, and its changes during the catalytic process through XAFS, as well as the neighboring structures of metal ions with extremely low content. In the field of materials science, X-ray absorption fine structure spectrometer (XAFS) is used for the characterization of various materials, the study of complex systems and disordered structural materials, the research of radioactive isotopes, the study of related properties of surface and interface materials, and the study of dynamic changes in materials.
