Welcome !!

Cyclotron Materials Irradiation Facility was established in 1987 at the former National Research Institute for Metals, STA, with a partial modification of the Environmental Effect Research Building and construction of the cyclotron housing at its Sengen site. The facility is now operated by National Institute for Materials Science. Since then, it has been actively utilized primarily for the irradiation effect studies of nuclear materials. Also a number of collaborative research with universities, national laboratories such as JAERI, and industries have been carried out using this facility. Presently, the 1st and the 2nd laboratories of Mechanical Properties Research Group of NIMS are jointly in charge of the facility.

One of the most significant features of this facility is a capability of in-situ irradiation experiments. Various techniques and equipment, as well as experiences, have been accumulated to satisfy these requirements. Furthermore, the cyclotron is dedicated only to the materials research so that a very long, continuous irradiation is possible in this facility. Such uniqueness makes it very valuable for the studies of radiation effects on materials even from a global point of view.
