Ion Sampling Through Small Orifices as Related to Stratospheric Measurements.

Abstract

An experimental laboratory apparatus has been assemblied to study the problem of sampling of low density ions from the stratosphere. The ion sampling efficiency was found not to depend strongly on the sampling orifice configuration or material of construction, and scaled in proportion to the orifice area. A model including the effects of ion diffusion to the sampling orifice plate is suggested to account for the low sampling efficiency observed. The apparatus was also used to develop an ion optical lens system for for use in a stratospheric ion measurement package. (Author)
