For any space mission utilising commercial or Hi-rel parts, or a mix of the two, an understanding of the radiation susceptibility of the active EEE parts and the associated impacts at equipment, sub-system and system level is invaluable and typically a project requirement. RASL provides expert consultancy no matter the stage of your project based on over 18 years experience in the space radiation field... When involved at an early stage, RASL can provide a specialist skillset into the design phase, particularly regarding component selection trade-offs, susceptibilities and de-risking. RASL also delivers informed guidance in determining the most useful radiation testing of components to perform, design mitigation options for SEE and shielding options for cumulative radiation effects. If the design is already established or heritage RASL can perform a full review to indicate areas of particular risk for which design changes, additional mitigations, etc. can be implemented. This can also be a very useful for retrospective in-orbit anomaly investigation. A radiation analysis of an equipment / sub-system / system and an understanding of the mission radiation environment can greatly reduce the risk of radiation induced failure in components which could lead to a loss of mission.
