PURPOSE: To carry out precise analysis of a sample by X-ray by making the temperature of the surface part of the sample which is a subject of X-ray diffraction be almost same as the temperature of a sample holder which is measured as the temperature of the sample. CONSTITUTION: A first stage 24 and a second stage 25 are installed as cooling parts in the inside of an air-tight case 5, a sample holder 41 is fixed in a second cooling point 27 of the second stage 25, a sample 4 is fixed in the surface of the sample holder 41 through a sample board 11, and at the same time a heat uniformalizing block 51 which surrounds the outer circumference of the sample 4 is installed in the sample holder 41. Consequently, heat is exchanged between the surface of the sample 4 and the heat uniformalizing block 51 by heat radiation and thus the temperature of the surface of the sample 4 can be kept almost same as the temperature of the heat uniformalizing block 51 and the temperature the sample holder 41 thermally conductively joined with the heat uniformalizing block 51. |
