Zusammenfassung:	PROBLEM TO BE SOLVED: To increase the efficiency of the cooling of a cold head by a pulse tube refrigerating machine, and at the same time, to achieve universality. SOLUTION: The lower end of a cold head 15 being cooled by a pulse tube refrigerating machine is thermally connected to one end of a cold finger 19 where an X-ray detection element 12' is provided at the other by using a flexible material 17 ' with large thermal conductivity. While the cold head 15 is positioned directly below a body 14 of the pulse tube refrigerator for retaining, the X-ray detection element 12' is allowed to oppose a sample S.
