In this research work, target performance under different spike pulse(s) time behavior is studied. It is shown that by applying two equal spike pulses with appropirate time delay, leads to enhancement of the target gain and reduction of the total ignitor energy. The lower spike energy is required for the lower total driver energy to be used for commercial energy production. Two trapezoidal pulses with 50 picoseconds rise time, different power levels, pulse duration, launching and delay time have been applied on a HiPER baseline target. A one- dimentional simulation by MULTI code has shown that the figure of merit for a double shock ignition scheme varies in a range of 1.1<FM<1.7. The FM>1 demonstrates that for the same compression energy the splitting of the ignitor pulse into two equal lower energy pulses has more benefit compared with the conventional method of shock ignition.
