How does an exploding foil initiator work

WebOur Exploding Bridge Wire (EBW) contains a lead-free explosive (CLCP) functioned with an ECOSSE PX-1 Firing Set and initiate secondary booster detonation in wireline guns. Exploding bridge wires (EBW) detonators have a small … WebThe exploding foil itself consists of a narrowing in the copper transmission line. The current will mainly heat this part of the foil. When a critical current and current rise time is exceeded, the foil will turn into a plasma. The plasma pressure and the Lorentz forces of the current will accelerate the flyer through the barrel.
