摘要

An object of the present invention is to efficiently improve uniformity of energy lines to be irradiated. A method of determining nuclear fusion irradiation coordinates according to the present invention is a method of calculating irradiation coordinates when energy lines are irradiated onto a nuclear fusion target, and comprises an initial arrangement step S202 of virtually arranging electric charges Q i at initial coordinates of the number of irradiation coordinates N B on a spherical surface S 0 set by using random numbers, a coordinate analysis step S203 of analyzing coordinates r i of the electric charges Q i in time series based on coulomb forces acting among the electric charges Q i by constraining the coordinates r i onto the spherical surface S 0 , potential evaluation steps S205 and S206 of determining a timing at which potential energies of the electric charges Q i were stabilized based on the coordinates r i , and an irradiation coordinate deriving step S207 of deriving coordinates r i at the timing at which potential energies were stabilized as irradiation coordinates of energy lines in a case where a nuclear fusion target is arranged at the center of the spherical surface S 0 .
