次世代放射光施設の展望

摘要

In the aftermath of the 2011 Great East Japan Earthquake and tsunami, the national government embarked on extensive development work in the region, including the Synchrotron Light in Tohoku, Japan (SLiT-J) project. Plans for this new 3 GeV facility sparked discussion about the great demand for next generation low emittance SR (Synchrotron Radiation) rings from the perspective of industrial science and technology. In 2017,"High brilliance light source project to make a new epoch of scientific and technological nation" was adopted as one of the "Road Map 2017” of Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan. In 2018, MEXT included "The promotion of next generation SR facility by the public and private sectors partnership" in 2018 budget. This paper reviews prospects of upcoming low emittance 3 GeV SR in Magnetic Materials Science.
