IEC 60749-17 pdf download Semiconductor devices – Mechanical and climatic test methods – Part 17: Neutron irradiation Once the neutron energy spectrum has been determined and the equivalent monoenergeticfluence calculated, then an appropriate monitor foil (such as 32S,54Fe, or 58Ni) should beused in subsequent irradiations to determine the neutron fluence. Thus, the neutron fluence isdescribed in terms of the equivalent...
