Definitions
- the present invention relates to a neutron generation target. More specifically, the present invention relates to a neutron generating target that has a palladium layer and a lithium layer on a substrate and generates neutrons by proton irradiation to the lithium layer, and has excellent durability and can maintain neutron generating ability for a long period of time. .
- the present inventors considered that it is necessary to suppress eutectic alloy formation at the interface between the lithium layer and the palladium layer in order to maintain the target ability and prevent peeling.
- the present inventors have conceived the present invention that it is preferable to set a predetermined barrier layer between the two layers in order to avoid direct contact between the lithium layer and the palladium layer.
