In the laser-driven ion acceleration experiments, several-tens MeV class protons with broad energy spectrum are accerelated by intense laser. To measure the precise energy spectrum of laser-accelerated protons, the stacked detector, which consists of CR-39 track detector and energy degrader, has been designed by using Monte Carlo particle transport simulation code PHITS.
