The IFMIF accelerator system is based on two similar beam lines running in parallel. Each D beam of 40 MeV/125 mA is transported by a High Energy Beam Transport (HEBT) line up to the liquid lithium target where neutrons will be produced. On the target, the specifications of the beam footprint mentioned a rectangular shape (20 cm 5 cm]) with a flat-topped homogenious current density profile and small energy spread. As a view point of the boundary condition management for the interface to the Lithium target, we demonstrate and simulate the beam after HEBT for clarifying the beam character on the beam robustness against the misalignment and mis-accelerated condition etc. regarding the effect to the Lithium target. The tolerance on beam axis off-set at HEBT inlet is estimated around 0.2 mm. The energy acceleration dependence shows small footprint robustness in case of mis-accelerated situation but better robustness for over-accelerated condition.

The IFMIF/EVEDA project, one of the three projects under contract with the BA agreement between EU and Japan, was started in the middle of 2007. During these two years, the design of an accelerator prototype has been progressed as the engineering validation activity and the base point of the engineering design activity for the IFMIF. The accelerator components for the prototype are being shifted to the manufacturing phase through the design reviews. In this article, the summary of the design of the prototype and the beam test plan of the prototype at Rokkasho BA site are described.

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.

Progress of the IFMIF/EVEDA prototype accelerator in fiscal year of 2008 is described. All the sub-systems of the prototype accelerator have started to design, settled the plan of the manufacturing and component tests and fixed the design parameters. As a result of the analysis of planning for the engineering validation of the IFMIF accelerator system, the project duration to be prolonged to the end of 2014 including some months for contingency was approved by the BA Steering Committee. In this article, the design status of each accelerator component, the interface between the accelerator components and the IFMIF/EVEDA Accelerator Building settled in International Fusion Energy Research Centre (IFERC) in Rokkasho and the proposed accelerator commissioning plan for the engineering validation will be presented.

One year has passed after the start of the Engineering Validation and Engineering Design Activities of the International Fusion Materials Irradiation Facility (IFMIF/EVEDA), which is a project performed under the Broader Approach Agreement of the fusion energy research between Japan and Europe. The project team to manage the overall activities was established at Rokkasho in Japan, and 12 people are working for planning and scheduling of whole project plan and for coordinating the annual work programs. In this year the management tools like WBS are defined and the detailed engineering design works are ready to start. However, as the collaboration between the project team and each contributing institutes in Japan and Europe is important to complete the fully integrated design of the IFMIF, a high level of the communication and sharing of information and knowledge is necessary to be established. The workshop like meeting is a good opportunity to discuss about the issues by all contributors at a single place. In the first meeting held in September the details of requirements/specifications for neutron generation, including ion beam - liquid lithium target - neutron irradiation capsule, concerned in their interfaces were defined.

The Accelerator Prototype Building for the IFMIF/EVEDA Project, in which enforce the engineering validation of the Accelerator, will be constructed in the BA site at Rokkasho-mura, Aomori-ken. Before detail design started, Japan and EU implementing agencies concluded the Procurement Arrangement based on agreed basic design. The building length is about 58 m east-west and about 37 m north-south. The area is about 2,020 m. The Accelerator Vault is center of north and south. RF and electric system are in north of the Vault, and HVAC and cooling water system are in south of the Vault. The control room is put in northwest of the building. Shielding design is based on the evaluation estimated by experts of Japan and EU. The Accelerator will accelerate deuteron to approximately 125 mA and 10 MeV, so the Accelerator Vault is covered with 1.5 m thickness normal concrete shield to protect radiation. To protect neutron streaming, the RF wave guides are through the underground pit into the Vault.
