Abstract
The first system with DIA type apparatus for synchrotron radiation study named MAX80 was installed at the Photon Factory in 1982. In this article, progress of the kick-off, planning, designing, construction and commissioning of MAX80 is briefly introduced. High pressure X-ray studies have suffered from the weak diffraction intensities, and synchrotron radiation was greatly expected to be a bright X-ray source. This makes the construction of MAX80 as a nation-wide project for high pressure community. Prof. S. Akimoto played an inevitable role, especially in the stage of beginning, in the construction of MAX80.
