Outline of Final Research Achievements

If portable apparatuses for X-ray diffraction analysis are applied more practically in the field of conservation science, the information about the material used in cultural properties will be obtained further. The aim of this research is to develop a 2-dimensional imaging detector for X-ray diffraction and to evaluate its performance.
An X-ray detector was constructed using gas electron multiplier foils. For data acquisition, a new method which processes signals efficiently was adopted. By using this system, the Debye-Scherrer ring from powder sample was successfully detected as a 2-dimensional image. The next step is to improve the resolution of images and safety for investigation of cultural properties.
