NEUTRON NUMBER ENHANCEMENT IN URANIUM THIN FILM WAVEGUIDES

摘要

The feasibility of the miniaturization of nuclear energy production is discussed. It is shown how the characteristics of 4 % enriched uranium thin film waveguides can be optimized in order to allow neutron concentration at high densities. The guiding uranium thin film is sandwiched between two ferromagnetic media. Since the neutron refractive index in thin magnetic films is spin dependent, this permits control of the neutron number in the uranium film by means of external magnetic fields.
