Qualification of Electronic Systems for Radiation Environments of High Energy Accelerator

Unlike a typical Radiation Hardness Assurance (RHA) methodology, this work presents a system level radiation qualification of a complex electronic system prior to component radiation characterization tests. Such a top-down approach reduces the beam time needed for qualification of components by carefully analyzing failure modes observed on the system level and performing only a subset of component tests for identified cases. This avoids system overdesign, reduces the testing workload and cost by accepting a certain residual failure rate.
