Quantitative method for designing systems with radiation damage considered

Abilities against radiation effects denote the sensitivity of systems to radiation damage, which can be achieved by design and manufacture, and represent the development level of radiation-hardening by design. In this paper, based on the QMU method, a flow of quantitative method for designing systems with radiation damage considered is raised. Firstly, the overall design of systems should be optimized, by dividing a system into different sub-systems, parts, and with different failure modes considered. Secondly, the radiation environment and the uncertainties have to be quantitatively verified. Then the corresponding radiation damage and uncertainties of the devices and sub-systems need to be evaluated, to make sure that the system operates safely. In the end, the overall ability of the system against radiation damage is predicted and verified.
