Base on this standard configuration, if we install related accessories, it can do analysis structure of thin films, texture of metal materials, stress measurement,and material structure under high and low temperature.
Within the most advanced technology at present, the accuracy of the goniometer had reached the current world advanced level. The X-ray source and detector can work stably for a long time to ensure the accuracy of measurement of diffraction peak position, peak shape and intensity. Phase structure analysis, including: phase content, grain size judgment, crystallinity, austenite content, cell measurement, second class stress calculation, diffraction line indexing, phase structure analysis,thin film material analysis, small angle particle size analysis, etc. DW-XRD-Y3500 includes high-stability X-ray generator, high-precision goniometer, scintillation detector, data processing software, and related application software.
Features of DW-XRD-Y3500
- High-frequency and high-voltage X-ray source: Solid X-ray generator greatly improves the stability of the measurement results of the XRD;
- Long life X-ray tube: metal ceramic X-ray tube, with good heat dissipation, high operating power (40kV×40mA), long service life;
- High precision goniometer: It is controlled by optical coding technology. Based on the traditional turboworm transmission technology, incremental optical coding technology is adopted. The optical digital coding can directly read the angle from both arms (invention patent), which greatly improves the accuracy and repeatability of the goniometer. The new generation of direct optical coding systems ensures the accuracy of the goniometer over the life of the instrument through the accurately calibrated Heidenhain optical encoder and trajectory tracking technology.
The goniometer adopts “coaxial &different core” technology to avoid the interference between the arms during scanning, ensuring the accuracy and stability of the goniometer.
- Multiple XRD accessories: high temperature, low temperature, multi-function and other XRD accessories installation to achieve “plug and play”, software automatic identification control technology, convenient for operators to use the instrument;
- Safe X-ray protection: X-ray scattering line protection device is more safe and reliable, the X-ray protection door is forbidden to open when the sample is measured, and double protection can avoid the operator from scattering line radiation under any circumstances.
