Target for neutron scattering installation

A target for a neutron scattering installation comprising:

• a container body configured such that a proton beam advancing approximately horizontally to a base of the container body enters a forward end of the container body and the proton beam divides the container body in two halves;
• a plurality of incoming-passage guide vanes with upper and lower edges contiguous with an inner surface portion of the container body, said plurality of incoming-passage guide vanes being disposed in a first half of the container body, laterally spaced apart from each other with a gradual enlargement of a radius of each incoming-passage guide vane, and curved toward a center of the container body in a direction from an end of the base toward the forward end of the container body;
• a plurality of return-passage guide vanes with upper and lower edges contiguous with the inner surface portion of the container body, said plurality of return-passage guide vanes being disposed in a second half of the container body, laterally spaced apart from each other with a gradual enlargement of a radius of each return-passage guide vane, and curved toward the center of the container body in the direction from the base end to the forward end of the container body;
• a liquid-heavy-metal inflow port configured to allow an inflow of liquid heavy metal from outside of the container body to the incoming-passage guide vanes in the container body;
• and
• a liquid-heavy-metal outflow port configured to allow an outflow of the liquid heavy metal from the return-passage guide vanes outside the container body.
