| Abstract: | Numerical simulation is made to SSJ/460°cylindrical electron detector boardedon DMSPsatellites. The potential distribution in the analyzer is found from solvingLaplace equation by means of SORiteration procedure. Based on the numericalsolutions of path equation, the responses of the detector are computed by using MontCarlo method. The appropriate choice of time and energy scale in the simulationleads to simple scaling laws of the response functions and the geometrical factor. |
