A linear induction accelerator (LIA) cell includes the pulse power system, the cavity and the reset system. By methods of cable delay and cable open circuit reflection, a burst double-pulse output can be generated by traditional LIA pulse power system. With the original reset system and the reconstructive power system, the experimental inductive cavity filled with ferrite cores will be worked in burst double-pulse mode. The experimental results prove that by simple reconstruction, an LIA cell can generate double accelerating pulses of interval less than 1 μs with the voltage intensity more than 200 kV, risetime less than 35 ns and flattop more than 60 ns.
