| 内容記述 | Over one century passes since plasma is thought to be produced in swift heavy ion irradiation, theoretically. However, it is still unclear if this irradiation forms plasma or not. In simulations, plasma formation was not incorporated using the binary collision model before our simulation model was proposed. We developed a new simulation model to confirm the production of this plasma. In heavy ion irradiation, huge number of molecules are ionized along the incident ion path (IP) and, as a result, a lot of molecular ions are produced. In our model, strong electric field created by these molecular ions and the effect of this electric field on the motion of secondary electrons are incorporated. Only our simulations reproduced the measurement of secondary electron. This measurement and our simulations indicated that slow secondary electrons were trapped by this electric field. These trapped secondary electrons are expected to form plasma. Further, using plasma theory, we derived a new formulation which almost reproduced our simulations. | |||||
