Macroscopic study of fine particle plasmas generated by the boat method

Abstract

The aluminum fine particles generated by the boat method were made into the fine particle plasmas by the irradiation of u.v. light and mixture of gaseous plasmas. The motion of the cloud around the charged sphere indicated that the fine particle cloud irradiated by u.v. light was in mixtures of positively charged particles and negatively charged particles. When fine particle plasmas immersed in argon glow discharge plasmas, the fine particles took a negative charge and were attracted to a positively charged small sphere and wire. This fact was clearly explained by Spitzer's investigation.
