The exploding foil, which is a main influence factor of exploding foil initiator (EFI), was studied to improve the utilization rate of energy in EFI. The burst currents of three bridge foils with different shapes were measured, and the sensitivity of initiation charge made of HNS-IV was tested by slappers. The test results show that, for O-shaped bridge foil, the burst current density is maximal, and the initiating voltage at 50% of firing probability of HNS-IV is minimal. The O-shaped bridge foil can be used to improve the utilization rate of energy in EFI and reduce the firing energy.
