Beam physics issue was investigated using a Malmberg-Penning trap device as a small experimental apparatus with electrons, which can be regarded as equivalent to the charged particle beam. In this study, we investigated numerically the particle dynamics in comparison with the experiment result from the view point of softening parameter adjusting. It is considered that the process of the fast electron generation was caused by multi-particle collisions.
