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。

In the frame of the IFMIF/EVEDA project, a high-intensity (125 mA) CW deuteron accelerator will be installed and commissioned at the Rokkasho Broader Approach (BA) site. The main objective of this 9 MeV prototype is to provide information on the feasibility of the design, the manufacturing and the operation of the two linacs (up to 40 MeV) foreseen for IFMIF. Based on the requirements for each system (accelerators, lithium target and tests facility) which are deduced from the IFMIF fusion material irradiation requirements, given by the users, the objectives of this accelerator prototype are defined and presented here. Also, because of the distributed nature of the design work and the procurement of the accelerator, organization of the installation and commissioning phase is essential. The installation and commissioning schemes, the organization proposed and the overall plans are presented.

The objectives of the IFMIF/EVEDA project are to produce the detailed design of the entire IFMIF facility, as well as to build and test a number of prototypes, including a high-intensity CW deuteron accelerator (125 mA @ 9 MeV). Most of the accelerator components (injector, RFQ, superconducting RF-linac, transport line and beam dump, RF systems, local control systems, beam instrumentation) are designed and provided by European institutions (CEA/Saclay, CIEMAT, INFN/LNL, SCK-CEN), while the RFQ couplers, the supervision of the control system and the building including utilities constructed at Rokkasho BA site are provided by JAEA. The coordination between Europe and Japan is ensured by an international project team, located in Rokkasho, where the accelerator will be installed and commissioned. The design and R&D activities are presented, as well as the schedule of the prototype accelerator.

During 6 years of IFMIF/EVEDA project since July 2007, design, construction, operation and maintenance of a prototype accelerator as an engineering validation activity and an accelerator engineering design activity for IFMIF including the interfaces with the Li loop target system and the material irradiation test facilities will be performed. The prototype accelerator consists of a 100 keV injector equipped with an ECR ion source, a radio-frequency quadrupole (RFQ) linac accelerating the beam up to 5 MeV, the first section of the superconducting drift tube linac (SC-DTL) accelerating the beam up to 9 MeV and subsystems. Most of the accelerator components are provided by European institutions (CEA/Saclay, CIEMAT, INFN/LNL etc.), while the RF couplers for the RFQ linac, the supervision of the accelerator control system and the accelerator prototype building constructed at Rokkasho BA site for the accelerator test and beam diagnosis are provided by JAEA. The R&D activities and the future schedule of the prototype accelerator of the IFMIF/EVEDA project will be presented.

幅広いアプローチ活動のもとで実施しているIFMIF/EVEDA事業では工学実証活動の大きな柱として、IFMIF加速器の前段部の原型加速器を製作し、青森県六ヶ所において建設・運転試験を行う準備が進められている。原型加速器では、IFMIF加速器の仕様(40MeV, 125mAのD
をCWモードで供給)を実現するうえで最重要課題とみなされる、入射器からRFQリニアック,超伝導リニアックの初段までの前段部を実規模で実証するのがねらいであり、9MeV, 125mA CWのD加速を目標に各機器及びシステムとしての性能を検証する。2012年以降、上流側から順次、機器の設置、及び調整試験を行い、2014年には原型加速器全体のCW運転を含む実証試験を行う予定である。全段を通して、ビームのエネルギー,ビーム形状等の計測を行うことで、設置誤差等によるビーム品質の安定性,良好さの確認が不必要な放射化を抑えるために必要である。また、RF源・RF伝送,ビームダイナミクス,冷却系・制御系等の補機系の開発,放射線安全等の検討も平行して進められている。
