Thick Lithium Metal Target for Fast Neutron Production |
|
| Abstract: | A high flux fast neutron was produced by the (d, n) reaction of a lithium metal target. A thick lithium layer for the target was prepared by a simple method of melt-coating on a copper plate. The fast neutron (>9 MeV) flux at a distance of 6mm from the target was (9.0±1.6)×l06 n/cm2·sec·μA with use of a 2.0 MeV deuteron beam. A flux of 2.7×109 n/cm2·sec was obtained by bombarding the target with the deuteron beam of 300 μA. |
