专利汇可以提供Recording of fast neutron images专利检索,专利查询,专利分析的服务。并且The formation of a permanent image of a fast neutron beam on cellulose nitrate film. The cellulose nitrate film is positioned between a converter film made of a suitable hydrogen-containing material, such as polyethylene, and the assembly attached to a back plate of aluminum. The neutron exposure is made with the neutrons impinging on the uncovered polyethylene face. Elastic scattering of fast neutrons by the nuclei of the hydrogen atoms in the polyethylene film produces protons which travel into the cellulose nitrate, leaving sensitized spikes therein. The cellulose nitrate film is etched by suspending in a sodium hydroxide solution and the image on the dry film viewed by transmitted light with the light source off the viewing axis.,下面是Recording of fast neutron images专利的具体信息内容。

  • 2. A method in accordance with claim 1 wherein the hydrogen-containing film component is selected from the group consisting of polyethylene, titanium hydride, zirconium hydride, and niobium hydride.
  • 3. A method in accordance with claim 1 wherein the hydrogen-containing film is polyethylene.
  • 4. A method in accordance with claim 1 wherein the low neutron scattering component is aluminum.
