Abstract

In this paper we report the detection and mass analysis of negative ions formed in a negative corona discharge using ambient air at atmospheric pressure. All of the detected anions are observed in the form of clusters, predominately containing water demonstrating the importance of humidity in atmospheric discharges. The formation mechanisms for such clustering phenomena are discussed
