  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.

  Ion sources providing high current beam with low emittance are required for accelerators to expand to apply them to fusion material science. A 100-keV, 150-mA class deuteron source with low emittance is required for an accelerator-based neutron irradiation facility to develop fusion materials, and the study for space charge effects in the range of a 20- to 150-mA deuteron beam is indispensable to extract the low beam emittance. For this purpose, each ion source to extract the beam current of 20, 50, 100, and 150 mA was designed by the Igun code, under the condition to extract a beam radius of 4 mm, a beam energy of 100 keV, and a normalized emittance of 0.2 PI mm mrad. In this article, these simulation results from the viewpoint of space charge effects will be presented in detail.
