Characterization of the Radiation Environment Capabilities of Exploding Foil Initiators (EFIs)

In response to the NavyÆs need to investigate and demonstrate the ability of low energy exploding foil initiators (LEEFIs or EFIs) to function in the Strategic Systems ProgramsÆ Trident II (D5) missile system, Corvid Technologies proposes to develop a concept for characterizing EFI bridge foil parameters during and after exposure to harsh radiation environments. Corvid will combine the experience of our advanced warhead design group and our radiation detection and testing group to develop a robust radiation effects testing plan. Our warhead group has performed dozens of energetics detonation tests using LEEFIs, while the radiation group has built novel radiation detectors and successfully carried out detector testing using radioactive sources and accelerated particle beams. Combining our warhead design and radiation testing capabilities uniquely positions Corvid to model, simulate, and live test EFIs exposed to high radiation environments to ensure compliance with the MIL-STD-1316 and MIL-STD-1901 standards. Upon completion of Phase I, we will deliver a plan to characterize EFIs with an accompanying analysis-based handbook that includes military specification pass/fail criteria, radiation and particle transport simulation results, and recommendations for EFI design advancement. These deliverables will support the Navy and SSPÆs mission to maintain and modernize the Trident II (D5) missile system.
