抄録

<jats:p>A high intensity deuteron ion source has been developed in order to increase the neutron flax from the D–T neutron source for Fusion Neutronics Source at JAERI. It is possible to extract more than 50 mA of deuteron beam at the beam energy of 50 keV. The lifetime of the tungsten filaments utilized in the ion source has been achieved in over 300 h with continuous operation. The high intensity deuteron ion source for the International Fusion Material Irradiation Facility is being designed on the basis of the experimental results and the experience obtained from the present ion source.</jats:p>
