Abstract
An explosive safety junction which can meet the high reliability and safety standards of conventional or nuclear weapon safing devices. The safety junction is an explosive logic device having an inlet trail which diverges into one or more tiers of safety trails and converges to form an outlet trail. The safety trails are crossed by a control trail which propagates a control detonation wave which severs the safety trails and prevents an input detonation wave from proceeding from the inlet trail to the outlet trail to detonate the weapon.
