A new approach for the prediction of the neutron-induced SEU rate

A new approach for SEU rate prediction in components submitted to neutron environment is presented. The method aims to take into account the characteristics of the secondary particles in terms of electrical effect. So, in addition to the critical energy/charge criterion generally used until now, two criteria are tentatively proposed : a critical LET and a limited distance in which energy must be deposited. The starting point of each computation is a common neutron-silicon interaction database.
