The diffractometer shown on the left is a specialized instrument for
 structural analysis of powder samples. An analyzer crystal and a detector are
 mounted on each detector arm. Only 15-degrees of rotation is required for
 measurement in an angle range of 60 degrees. This instrument incorporates
 MAX-G400 and MAX-G600. The axial coincidence of the ??-2???axes is kept
 at approximately 5 ??m. This instrument is now in service at SPring-8 (Super Photon ring-8 GeV) BL08B2 in Japan.
