The core function of the graphite curved crystal monochromator is to precisely filter out the desired Kα characteristic radiation from complex X-ray signals. This process is based on the Bragg diffraction principle, utilizing the precise arrangement and curved shape of the graphite crystal lattice to achieve selective transmission of X-rays. In practical applications, this component effectively eliminates interference from continuous X-rays, Kβ radiation, and fluorescent radiation generated by the sample itself. This filtering effect is particularly significant when analyzing samples containing elements such as manganese, iron, cobalt, and nickel using copper-target X-ray tubes. Dandong Tongda offers both graphite curved crystals and flat crystals. The use of graphite curved crystal monochromators can enhance the peak-to-background ratio, reduce background noise, improve the resolution of weak peaks, achieve a reflection efficiency of n ≥ 35%, and lower the diffraction angle of the diffractometer. The mosaic spread is ≤ 0.55°, and the crystal surface can be tilted by ±2°. These parameters ensure the stable performance of the instrument over long-term use. In X-ray analysis, the quality of data directly impacts the reliability of research conclusions. The graphite curved crystal monochromator significantly improves the quality of the collected signals by enhancing the peak-to-background ratio and reducing background noise. For diffractometer applications, this component also moderately lowers the diffraction angle, making weak peaks more distinct and improving the instrument's ability to resolve trace components. While this improvement may seem minor, it can play a critical role in key experiments.

Multiple Safety Interlocks: Equipped with multiple safety protection features including door-operation interlock, emergency stop, and overdose protection, ensuring the safety of operators and the environment. Precise Control and Good Reproducibility: Utilizes a digital control system, allowing users to precisely set irradiation parameters—including voltage (kV), current (mA), and irradiation time—via a touchscreen interface. The system enables stable dose output, ensuring uniformity in experimental conditions and reproducibility of results. Easy Operation and Simple Maintenance: The user interface is simple and intuitive, easy to learn and operate, lowering the barrier to use. Compared to isotope sources which require regular replacement and decay monitoring, the main maintenance for this equipment focuses on the periodic replacement of the X-ray tube, resulting in relatively fixed and manageable long-term maintenance costs. Flexible Sample Compatibility: The irradiation chamber is designed to accommodate various samples, from cell culture dishes and multi-well plates to small animals (e.g., fruit flies, mosquitoes, or mice). The sample stage can be designed to rotate, ensuring uniformity in radiation dose distribution. III. Main Application Scenarios Biomedical Research: Used for creating immunodeficient animal models (e.g., ablating bone marrow cells in mice), inducing cell apoptosis, synchronizing cell cycles, oncology research, and pre-treatment for stem cell transplantation. Sterile Insect Technique (SIT): This is a significant application area. It can be used to irradiate pupae of agricultural pests (e.g., Mediterranean fruit fly) or mosquitoes to render them sterile, thereby supporting green, pollution-free population control programs. Material Modification Research: Can be used to study the effects of X-rays on the properties of various materials (e.g., polymers, semiconductors). IV. Typical Model Parameters (Using WBK-01 as an example) X-ray Tube Voltage: Adjustable based on requirements, typically within a range from several tens to hundreds of kilovolts (kV), to suit different penetration depths and dose rate needs. Dose Rate: Can be adjusted based on voltage, current, and distance to meet the specific requirements of different experimental protocols. Uniformity: Ensured through optical system design and a sample rotation mechanism, guaranteeing uniform dose distribution within the irradiation field for reliable experiments. Summary The core value of the Dandong Tongda X-ray Irradiator lies in its replacement of inconvenient radioactive isotope sources with a safe, controllable, electrically generated X-ray source.
