The process of electron-ion collisions and superheated electron transport It is pointed out that the addition of weak ions in the electron ion enhances the collision absorption, increases the temperature of the hot electron and decreases the field energy when the electrostatic wave breaks down, which changes the total energy and distribution of the hot electron and concentrates on The existence of electron-ion collisions also enhances the self-consistent electric field and hinders the transport of hot electrons, which is also one of the reasons for the decrease of the energy of the hot electrons. In the meantime, in order to ensure the reliability of the calculation results, The influence of the initial conditions on the PIC simulation shows that it is easy to introduce non-physical factors into the random hot start of the space position, which has a significant adverse effect on the calculation results
