Multi-anvil-type high-pressure systems have been successfully applied to synchrotron radiation experiments. The first system with DIA type apparatus named MAX80 was installed at Photon Factory in 1980. A Kawai type double stage assembly with thrust of 1500 ton was installed at the 3rd generation SR facility SPring-8 in 1997. The family is widely spread all over the world. Using these systems, the quality of X-ray diffraction under pressure was revolutionary developed. In addition to the diffraction experiment, XAFS, viscosity measurement, density measurement, high pressure generation using sintered diamond anvil and ultrasonic measurement have been newly developed and opened new fields in high pressure science.
