Abstract
We have proposed a new configuration for the improvement of neutron yield without the application of external ion sources in an inertial electrostatic confinement (IEC) device. The application of a double grid cathode to the IEC device is expected to generate a higher ion current than a single grid cathode. This paper verifies the effect of the double grid cathode by both fluid and particle simulation. Through the fluid simulation the optimal shape and applied voltage of the double grid cathode is determined, and through the particle simulation the usefulness of that is confirmed.
