Abstract :
We have simulated an IECF (inertial electrostatic confinement fusion) device by developing and using a particle code. Because a virtual anode is built up at large current region, which decelerates ions and reduces neutron yield, suppression of this virtual anode by supply of electrons from an additional electrode inside the cathode has been tried in the simulations. The simulation results show that with increase of electron supply current, potential profile changes drastically and the neutron yield increases at a threshold value. Also the mechanism of the drastic change has been explained well
