What is it about?

This study is about neutralizing of an ion plasma beam by electrons emitted by an external source. We discovered unusually long solitary waves during the neutralization process. This work is a theoretical analysis which sheds light on why such unique phenomena is seen in a neutralizing ion beam.

Why is it important?

The study of these waves is important because these solitary waves hinder the process of beam neutralization as they create 'bumps' in the beam.


This article is a culmination of two year effort in understanding beam plasma waves from numerical and theoretical point of view. We hope this article answers some and also creates more questions about similar waves found in plasma experiments and space plasmas.
