Abstract

A simple method to confirm the dust charge number and the radius of dust particles in dusty plasma is deduced. Based on the orbit-limited motion method and the charging theory of dust particles in dusty plasma, the equation of dust particles charging is formed, and the formula of the ratio of dust charge number to the radius of dust particles is deduced. Based on the data of MD-06 campaign, the ratio of dust charge number to the radius of dust particles at occurring polar mesosphere summer echoes(PMSE) is analyzed. The dust charge number and the radius of dust particles are obtained. The results show that the average charge number of dust particles in the polar mesopause is less than one and the average radius of dust particles is about 20nm.
