Method of determining nuclear fusion irradiation coordinates, device for determining nuclear fusion irradiation coordinates, and nuclear fusion device

Abstract

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 Sof virtually arranging electric charges Qat initial coordinates of the number of irradiation coordinates Non a spherical surface Sset by using random numbers, a coordinate analysis step Sof analyzing coordinates rof the electric charges Qin time series based on coulomb forces acting among the electric charges Qby constraining the coordinates ronto the spherical surface S, potential evaluation steps Sand Sof determining a timing at which potential energies of the electric charges Qwere stabilized based on the coordinates r, and an irradiation coordinate deriving step Sof deriving coordinates rat 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.
