A beam plastic body for treatment is caught to neutron

The utility model provides a beam plastic body for treatment is caught to neutron, including the beam entry, the target, border on in the slow fast body of target, the encirclement is at the external reflector of slowly inviting, personally experience sth. Part of the body with the thermal neutron absorption that the slow fast body borders on, the setting is in internal radiation shield and the beam export of beam plastic, the nuclear reaction takes place in order to produce the neutron with the proton beam that incides from the beam entry for the target, the neutron forms the neutron beam of injecing a main shaft, delay the fast body subzone to the super -heated in of will slowing down from the neutron that the target produced, the material that delays the fast body is by containing liF, li2CO3, al2O3, alF3, at least a material among caF2 or the mgF2 is made, it becomes piece through powder sintering process by powder or powder pressed compact through powder sintering equipment, the reflector will deviate the neutron of main shaft and lead back the main shaft in order to improve super -heated neutron beam intensity, the thermal neutron absorption body and function is in the absorption heat neutron in order to avoid when treatment and shallow layer normal structure to cause too much dosage, neutron and photon that the radiation shield is used for shielding the seepage shine the normal structure dosage in district in order to reduce the non -.
