Development of the compact furnace for the in-situ observation under ultra-high temperature by synchrotron x-ray surface diffraction

摘要

We have established the grazing-incidence x-ray diffraction (GIXD) method under ultra-high temperature for in-situ crystal growth observation. For this purpose, we have developed the compact furnace which can be mounted on a goniometer used for the GIXD experiment. Using the custom-designed furnace, we have succeeded in controlling very high temperature around 1800℃. Subsequently, we have proved the performance of the furnace through the measurement of the temperature dependence of a-lattice constant of 4H-SiC in the range from room temperature to 1500 ℃.
