| Research Abstract |
In the Tokai BNCT facility,an 8-MeV proton accelerator is used to realize very low residual radioactivity. An 80-kW beam power is required to generate very intense neutron flux. Target development is a key issue to realize both low residual radioactivity and high blistering tolerance. A beryllium plate with 0.5-mm thickness and 180-mm diameter is bonded on the blistering tough metal in which proton beam is stopped. We use a heat sink made of copper to remove very high heat density of 4.5 MW/m2. Thus this two tier (beryllium and blistering tough metal) has been bonded of a copper heat-sink. Three tier target has a heat conductivity of 200W/m.K, which is about half of pure copper. We successfully have developed the three tier blistering tolerant neutron target for BNCT.
