Abstract:
The main scope of this presentation is the test of SEEs induced by neutrons on electronics intended to be operated in a neutron flux near a fusion reactor (DD or DT plasma neutrons). Regardless of the intensity of the gamma and neutron fluxes, this presentation focuses on the energy spectra of neutrons and its effects, whose energy degradation can vary from one place to another in the reactor building depending on the elastic and inelastic interactions of neutrons with the surrounding structures, such as shields and walls.
Although the neutron fluxes depend on the design of the machine and the building as well as the operation of the reactor, the energy spectra of the neutrons should be quite similar in fusion reactors. Analogies but also differences can be evoked comparing with the case of Fission reactors and with the well described case of the natural atmospheric neutron spectrum.
