内容記述
If portable apparatuses for X-ray diffraction analysis are applied more practically in the field of conservation science, it would be possible to obtain further information about the materials used in cultural properties. The aim of the present study is to develop atwo-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, new IC chips called “STRIPIX”,which were developed for tracking detectors in high energy physics,were mounted on the signal readout board.Pixel-type electrodes arearranged two-dimensionally on the STRIPIX chip and electric signals deposited on each row and column are collected and added,thus reducing the number of readout channels.By using this new and simple system, the Debye-Scherrer ring from a powder sample was successfully detected as a two-dimensional image. The next step is to improve the resolution of images and safety to cultural properties during investigation.
