Özet

A new cathode modeling with stationary multi-component cathode approach is suggested for an inertial electrostatic confinement fusion device and some preliminary simulation studies based on the potential function of this cathode have been presented. The ions are accelerated due to the Coulomb force on a 2D plane and the central grid is assumed to have 6 point-wise and negatively charged at the middle. The model includes a repulsive force that stems from the screening effect of atoms at the vicinity of cathode. The simulations have proven that the particle trajectories are highly complex in the new potential well; in fact, the prediction of the particle route is observed to be strictly dependent on the control parameters such as the grid radius, ion current, voltage and initial position of the ion.
