Fiber Accessories utilize the X-ray diffraction (transmission) method to analyze the unique crystal structure of fibers. Parameters such as crystallinity and full width at half maximum (FWHM) are used to determine the orientation degree of the sample. ​ Main Functions and Features of Fiber Accessories: Maintaining Fiber Orientation: This is the most critical aspect. Fibers typically exhibit high anisotropy, with crystals preferentially aligned along the fiber axis. Fiber Accessories can straighten and secure fiber bundles, preserving their original orientation to measure orientation degree and distribution. Adapting to Different Sample Forms: Single Fiber: Extremely thin, requiring special clamps or frames for fixation. Fiber Bundle: Multiple fibers arranged in parallel; Fiber Accessories must align and tension them uniformly. Fiber Fabric: Materials like cloth require a flat frame to stretch them taut. Enabling Special Testing Modes: Transmission Mode: Suitable for thin fiber bundles or single fibers. Fiber Accessories include a dedicated frame to tension the fiber, allowing X-rays to penetrate the sample directly. Reflection Mode: Used for thicker fiber bundles or fabrics. Fiber Accessories provide a flat sample surface for this mode. Fiber Sample Holder: This is a simple metal or plastic frame equipped with slots or knobs. During operation, both ends of the fiber bundle are fixed to the holder, and knobs are rotated to tension the fiber, keeping it straight and parallel. The entire holder can be placed in the XRD goniometer for testing, similar to a standard sample. In summary, Fiber Accessories for XRD are specialized sample fixation devices designed for testing fibrous samples with anisotropic structures. Their core function is to maintain and regulate fiber orientation, while advanced versions may support in-situ stretching and other functionalities, providing critical insights into the orientation of crystal structures in fibers.

In the field of lithium-ion battery research and development, understanding the dynamic changes in the microstructure of electrode materials during charge and discharge processes is crucial. Traditional offline detection methods cannot capture these changes in real time, while the emergence of in situ characterization techniques provides researchers with a powerful tool. Leveraging its expertise in X-ray diffraction (XRD) technology, Dandong Tongda Technology Co., Ltd. has developed an in situ battery accessory for battery research, offering an efficient window to explore the reaction processes inside the "black box" of batteries. Technical Principle: Dynamically Monitoring Microscale Changes in Battery Materials The core design goal of Dandong Tongda's originally battery accessory​ is to enable real-time monitoring of the evolution of the crystal structure of electrode materials using X-ray diffraction (XRD) technology while the battery is operating normally (during charge and discharge). This accessory typically needs to work in synergy with an electrochemical testing system (such as the LAND battery test system) and an X-ray diffractometer (such as Tongda Tech's TD-3500 model). It forms a specialized battery chamber that allows X-rays to penetrate and probe the electrode materials of the battery during operation. The key lies in the design of window materials (such as beryllium windows) with extremely low X-ray absorption rates on the battery components, ensuring effective incidence and emission of X-rays. Simultaneously, the accessory integrates necessary electrodes, insulation, and sealing components to ensure normal electrochemical reactions and maintain excellent sealing during testing. Key Functions and Application Value The value of this in situ battery accessory lies in its ability to help researchers intuitively and dynamically observe a series of microscopic changes in electrode materials during battery charge and discharge processes: Real-Time Observation of Phase Transition Processes: Many electrode materials undergo phase transitions during lithium-ion intercalation and deintercalation. In situ XRD can capture the formation, disappearance, and transformation of these phases in real time, which is critical for understanding the battery's reaction mechanisms. Monitoring Lattice Parameter Changes: By precisely tracking the shifts in XRD diffraction peaks, subtle changes in lattice parameters can be calculated, reflecting the expansion and contraction of the lattice. This is closely related to battery performance metrics such as voltage platforms and cycle life. Unveiling Capacity Decay Mechanisms: Capacity decay during battery cycling is often related to structural degradation of electrode materials, side reactions, and other factors. In situ monitoring can correlate electrochemical performance degradation with structural changes, providing direct insights for improving battery materials and optimizing design. Accelerating New Material Development: For evaluating novel electrode materials, in situ XRD technology can quickly provide key information on structural stability and reaction pathways, speeding up the R&D process.

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.

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.
