| Outline of Final Research Achievements |
For liquid metal lithium jet used as a beam target in accelerator-based neutron source such as IFMIF, we proposed innovative magnetically guided liquid metal target (MGLT), which enable us to control liquid metal jet using magnetic field, and demonstrated the performance of MGLT using two dimensional simulation. In this demonstration, we showed that interaction coefficient, which was the ratio of the inertia force with the electormagnetic force, was effective to get the condition for curving liquid metal jet by magnetic field. Next, we optimized the size and the shape of MGLT for gallium jet, which is the alternative liquid metal to lithium, used in our substantiative experiment. In addition, using simulation, we obtained experimental conditions of gallium jet and demonstrated the performance of MGLT for gallium jet. Finally, based on these results of simulation, we designed and made gallium test loop.
