Nuclear Reactions Induced by 14 MeV Neutrons

in fairly good agreement if the region sensitive to the SEUs (sensitive volume) is
properly dened. Adopting the calculation to atmospheric neutrons, the frac-
tion of the SEU rates induced by elastic scattering accounted for approximately
26%–32% of the total fast-neutron-induced SEUs in the atmospheric neutron
environment. Reducing well depth will eectively reduce the number of SEUs.
Lambert etal. (2006) investigated the sensitivity of SOI and bulk SRAMs to
neutron irradiations with energies from 14 to 500 MeV. e technology sen-
sitivity is analyzed with both experiments and Monte Carlo simulations. In
particular, simulations include the nuclear interactions of neutrons with both
