In order to improve energy utilization ratio of initiation system, three kinds of exploding foils Cu, Cu/Au and Cu/Al/Ni were prepared by the closed-field unbalanced magnetron sputtering iron plating technology and pico-second laser micromachining system.And their electro explosive performances were studied by designed test circuit.It is found when charging voltage are 2000 V or 2500 V, initiation voltage can match with Cu exploding foil in high energy utilization rate.And the electrical explosion performances in three kinds of exploding foils were also tested at 2000 V and 2500 V.which indicates that Cu/Al/Ni burst current is much higher than the Cu/Au and Cu with an increase of 36% compared with Cu at charging voltage of 2500 V, and 15% compared with Cu at 2000 V.The plasma plumes generated during the explosion in three kinds of exploding foils were observed by high-speed photography when the charging voltage is 2500 V.Results show that the size of the plasma plumes Cu/Al/Ni > Cu/Au > Cu.Finally, Cu/Al/Ni exploding foil is more conducive to low energy exploding foil initiator systems under the same initiating condition.
