	The International Fusion Materials Irradiation Facility (IFMIF) aiming at generating materials irradiation test data for DEMO and future fusion power plants is based on an accelerator-driven, D-Li neutron source to produce high energy neutrons at sufficient intensity and irradiation volume. IFMIF Engineering Validation and Engineering Design Activities (EVEDA) have been conducted since mid 2007 in the framework of the Broader Approach Agreement and the scope of the project has been recently revised to set priority on the validation activities, especially on the Accelerator Prototype (LIPAc) with extending the duration up to mid 2017 in order to better fit the development of the challenging components and the commissioning of the whole accelerator. This paper summarizes the present status of the LIPAc, currently under construction at Rokkasho in Japan, outlines the engineering design and the developments of the major components, as well as the expected outcomes of the engineering work, associated with the experimental program.

THPPP003	Coupling Impedance Study of the New Injection Kicker Magnets of the JPARC Main Ring	3725

	New lumped inductance kicker magnets have been developed for the J-PARC main ring injection system. For high intensity beam operation, the beam coupling impedance of the new kickers is a critical issue, which not only generates significant heating inside the ferrite impairing the performance of the kickers, but also drives beam instability. Numerical simulations based on CST studio have been studied during the design stage to optimize the kicker structure. Impedance measurements based on wire method have been carried out. The measured results agree well with the simulation results.

THPPP004	Design and Test of Injection Kicker Magnets for the JPARC Main Ring	3728

	The present injection kicker magnets of the JPARC main ring consists of three transmission type kickers. To overcome the operational problems, four lumped inductance kicker magnets have been developed for the simplicity and the high reliability. The tight requirements on the rise and fall time create difficulties for the new design. Magnetic field measurements, coupling impedance measurements and have been carried out. The measurement results show that the new kicker magnets can satisfy the requirements of beam injection.

	An accelerator-based BNCT (Boron Neutron Capture Therapy) facility is now under construction and the entire system including the patient treatment system will be installed in the Ibaraki Medical Center for Advanced Neutron Therapy (tentative name). The linac specification is 8 MeV with 10 mA of average current (80 kW) with a duty factor of 20%. The linac is composed of a 3-MeV RFQ and a drift-tube linac and can accelerate a peak current of 50 mA up to 8-MeV. The neutron producing target is a 0.5 mm thick beryllium disk 150 mm in diameter which is formed on a heat sink plate. The material components used in the neutron moderator system, including the target, should be selected to have a reduced residual radio-activity. Special attention should be paid to mitigate the swelling of target materials due to hydrogen implantation as well. The development of an accelerator-based BNCT suited for practical application requires input from a wide spread of technical specialties. To obtain the needed breath and strength, we have organized our team with contributing members from diverse institutes and companies. The research and development activities of this integrated team will be presented.
