Abstract: A doublepulse line induced accelerator (LIA) module is reconstructed based on a usual singlepulse LIA module. By changing the length of one of the cables between the inductive cell and the Blumlein pulse forming line, two induction pulses are generated by the ferrite cores inductive cell. The interval time of the pulses is adjustable by changing the lengths of the cable, also the input voltage is changed in different experiments. The results show that it is possible for the existing LIA power system to generate multipulses; the ferrite cores of LIA can induct multipulses when their voltagesecond range is enough; and the resetting effect of the cores is tied up with the resetting time and resetting voltage.
