Abstract: A 100 kV/60 kJ electric gun was developed. The electrical character and geometric scale of the load,as well as the experimental setup,were presented. The experimental results indicate that the flyer has good integrality and high flatness. The electric gun can accelerate the 0.15-mm-thick Mylar flyer with the diameter of 18 mm (53 mg) to 8.1 km/s,and the 0.2-mm-thick Mylar flyer with the diameter of 12 mm (32 mg) to 9.6 km/s,respectively. The 60 kJ electric gun has high driving capability and can be used as an effective driver to carry out dynamic response of materials under high strain rates and some other relative investigations.
