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.

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.

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.

IFMIF/EVEDA Prototype Accelerator Building is a facility for validation of prototype accelerator which will be made for the Engineering Validation and Engineering Design Activity (EVEDA) of the International Fusion Material Irradiation Facility (IFMIF). This building is constructed the International Fusion Energy Research Center in Rokkasho village, Aomori prefecture, as a part of the Broader Approach activity which is an international cooperation between Japan and EU. The detail design was completed in 2007, and its construction work was started in March, 2008. The building is an one story, steel construction. The width of east-west is 58 m, north-south is 37 m, maximum height is 10.95 m, and floor area is 2019.5 m. The Accelerator Vault which made of concrete is in center of the building. The southern side is HVAC and cooling machines room, and the other side is Radio Frequebcy power supply area. Its underground was constructed in 2008, and the Accelerator Vault was constructed in May, 2009. Now, roofing work is doing. The building will be completed in May, 2010.
