The so-called “Missing Xe” problem is a long standing unsolved problem and is related to many fields in Earth science: formation process and evolution of the Earth, origin and evolution of the atmosphere, and geochemistry. Although the long-held expectation was the retention of xenon in the iron-rich core, present experimental result clarified that it is unlikely to occur. This implies that we have to reconsider the missing xenon problem and encourage many scientists to pursuit other possibilities.

X-ray diffraction studies under high pressure using synchrotron radiation at the Photon Factory are reviewed. In 1983, a system named "MAX80" was constructed, which consists of a cubic anvil type high pressure vessel combined with a 500-ton hydraulic ram and a posi-tioning stage. High quality powder X-ray diffraction studies can be performed using this system in the pressure range up to 12 GPa and in the temperature range from 300 K to 1700 K. Various studies such as precise measurement of the equations of state, phase diagram, and the kinetics of the phase transformations have been carried out using this system.
