Simulation of cylinder SGEMP radiated by X-ray
2021
The whole 3D simulation of SGEMP from X-ray to electromagnetic field environment is realized by developing 3D PIC code with compiling MC function modules in it, so that photoelectrons of arbitrary energy, angular, spatial and time distributions which calculated by transport code JMCT could be transformed into the initial current source used in PIC simulation directly. The simulation results are analyzed preliminarily. It is obtained that the emitted current is 0.11 A while the electric field could get 100 kV/m and magnetic field is over 1.6×10−6 T when the blackbody X-ray of temperature 1 keV and emitted fluence 1 J/cm2 perpendicularly irradiates the side of cylindrical object with material of Al and height of 2.0 cm, radius of 1.0 cm.
