As a method to evaluate high-pressure equation of state data of fissile materials precisely and safely,we numerically examined an experiment based on a subrange target of fissile materials and a pulsed heavy-ion beam.To heat the target homogeneously,we adjusted the target thickness and the incident beam energy so that the Bragg peak could be used for energy deposition[1].For this setup,we calculated hydrodynamic motion of the target using a 1D code[2].
