An Inertial Electrostatic Confinement (IEC) device is often referred to as a portable neutron source and can be used as a research reactor due to its simple structure and low cost. This device includes two electrodes and a feed stalk. By using a power source, a voltage difference is applied between two electrodes, by means of a feed stalk connected to the inner electrode. A lot of experimental and simulation research has been done on this device all over the world. In this work, the IEC device is kinetically modeled using the particle-in-cell (PIC) method. This modeling has been done at a constant voltage of −25 kV and pressure range of 1 x 10&sup(−2) to 1 x 10&sup(−4) Torr. According to the obtained results, the number of ions increases with decreasing pressure. At 1 x 10&sup(−2) Torr, the number of ions is equal to 1.03 x 10&sup(11), while at 1 x 10&sup(−4) Torr, this value increases to 9.35 x 10&sup(12). This increase in ions shows that the mean free distance increases with the decrease in pressure, and the probability of collision between ions and neutrals decreases.
