Multipoint Exploding foil Initiator System

This proposal details the development of a multipoint exploding foil initiator trigger system that enables programmable delays between EFI detonations. The temporal jitters are less than 50 ns from the initial trigger signal to the firing of each EFI. This enables precise control of the detonation wave in an explosive from multiple initiation points. The system is comprised of a control module which generates programmable delay signals to 1.5 cm3 EFI drivers that are co-located near the EFI itself to minimize inductive and resistive losses. All components are COTS for reduced cost and quick development. Feasibility is demonstrated at the end of the Phase I OPTION by measuring the performance of a system firing 4 EFIs with independent delays for each EFI up to 5 microseconds and 50 ns jitter. Two EFI manufacturers and a commercial end user are assisting in this development to assure its success.
