Plasma formed by heavy-ion irradiation has been investigated in this study. For this study, a simulation model that effectively uses recent computers is developed. Here, the effect of the Coulomb interaction between secondary electrons on the formation of plasma is demonstrated. This interaction plays a role in plasma swelling and decreases the probability of secondary electrons escaping from the electric field formed due to heavy ion irradiation.
