Exploding foil initiator using a thermally stable secondary explosive

摘要: An exploding foil initiator for operation with perforating gun assemblies or other equipment placed in a well borehole is set forth. This device utilizes bridge adjacent to flyer layer and barrel having central bore. When the vaporized, disk cut by bore, directed through bore of barrel, traveling at high velocity deliver impact against secondary explosive. The explosive formed BRX which pellet material 1,3,5-trinitro-2,4,6-tripicrylbenzene. Detonation accomplished voltage, current pulse substantial voltage amplitude about 1100 not more than 2000 volts.
