An electrostatic Particle-in-Cell (PIC) simulation is developed to investigate the origin of irreversibility in the electron plasma wave By giving two external pulse electric field to the plasma the temporal plasma echo is observed in the PIC simulation If Coulomb collisional effects are considered the plasma wave echo will become irreversible phenomena The Coulomb collisional effect is manifested as the time-shift of the echo peak and the damping of the echo peak amplitude Binary collisions into the PIC simulation is incorporated to demonstrate collisional effects on the plasma wave echo A simplified algorithm which can approximate the N-body force calculation is employed learning from the Barnes and Hut algorithm by the gravitational problems
