SPEED-1500 (SPring-Eight Energy Dispersive system with a hydraulic ram of 1500 ton, Fig. 1) is a uniaxial large-volume press consists of a Kawai-type high-pressure vessel　and two single-axis goniometers (the vertical one is for CCD imaging and the horizontal one is for X-ray diffraction with 2θ range from -10° to 23°). SPEED-1500 can be moved in the 4-axis directions (x-, y-, z-axis) with a precision of 1 micron around the z-axis rotation. SPEED-1500 is a double-stage type (Kawai-type) compression with 1500-ton ram force, and the outside first-stage consists of six cubic type anvils in the [100] axis direction. The inside second-stage consists of eight cubic anvils, each of which has one corner truncated into a triangular face. The eight faces form an octahedral cavity. The eight second-stage anvils that are compressed by the six first-stage anvils compress an octahedral shaped pressure medium (Kawai-type (6-8 type) cell). In the present system, a 26 x 26 x 26 mm3 tungsten carbide (WC) cube can be used as the second anvil. 30 GPa over 2500 K has been reached with the WC anvils. 

A white X-ray beam from the bending magnet light source is collimated with vertical and horizontal slits to form a thin beam possessing a cross section of typically 0.05 x 0.1 mm2. In order to carry out the energy-dispersive X-ray diffraction on the Kawai-type system, the first-stage anvils are cut holes to pass the X-ray beam. The incident white X-ray beam from the first-stage passes through the gaps between the second-stage anvils in a horizontal plane. X-rays diffracted by samples under high-pressure and high-temperature is detected by a pure Ge solid state detector (Ge-SSD) with a 4096 multi-channel analyzer. Diffraction data can be obtained with an energy range from 20 to 150 keV. Use of a collimator (0.05 mm width) and a receiving slit at a fixed angle to the direct beam permits only the diffracted X-rays from the sample to be detected. The horizontal goniometer covers a range of 2θ angles from -10 to 23° with an accuracy of 0.0001°. The X-ray acquisition time to obtain a diffraction profile is typically one to several minutes. 

X-ray radiography system compose of GaGG sintilator, Mirror, lens and CMOs Camera. 

A Si(111) double crystal monochorometer can extract X-rays with energies of 30-60 keV. Monochromatic X-rays pass 8 mm above white X-rays.
