国際核融合材料照射施設(IFMIF)は核融合材料開発のための加速器型中性子源である。2007年6月より始まったIFMIFの工学実証工学設計活動(EVEDA)では40MeV, 125mAの重陽子加速実現のための原型加速器を青森県六ヶ所村に建設中である。原型機は超電導加速器の初段部までをつくり、9MeV, 125mAの運転を実現するのが目標である。その主な技術仕様や大電流加速器の課題を述べるとともに、原型機運転において期待される成果を概説する。

International Fusion Materials Irradiation Facility (IFMIF) is an accelerator-based neutron irradiation facility dedicated for development of fusion materials. Engineering Validation and Engineering Design Activities (EVEDA) phase of IFMIF project has been initiated in June 2007 and a prototype of the IFMIF accelerator (40 MeV - 125 mA CW Deuteron) is under construction in Rokkasho, Aomori. The target of the prototype is 9 MeV - 125 mA CW beam operation, which is full scale prototyping up to the first tank of superconducting linac section. In this report, the major technical specifications and issues of this extremely high-power machine are overviewed and expected results through operation in future are summarized.
