Preparation of Al_2O_3 Insulation Layer in Laser-driven Flyer Target

CHEN Shao-jie,WU Li-zhi,SHEN Rui-qi,YE Ying-hua,HU Yan(School of Chemical Engineering,Nanjing University of Science and Technology,Nanjing,210094)  
The velocity of the flyer can be improved significantly with Al2O3insulation layer to ensure reliable initiation of high explosives.In this paper,the Al2O3insulation layer in laser-driven flyer target was prepared by RF magnetron sputtering.In conditions of 238W sputtering power,0.4Pa sputtering pressure,30sccm Ar flow and 11cm target-substrate distance,the deposition rate of Al2O3film is 125nm/h.The prepared Al2O3film is showed amorphous structure by X-ray diffraction(XRD) characterization.The surface of the Al2O3film is uniform and dense observed by scanning electron microscope(SEM),and with no holes or other defects.The study provides support to further multi-layer flyer target preparation.
