Chambers for the electrodynamic containment of charged aerosol particles

Abstract

Chambers capable of the electrodynamic containment of electrostatically-charged 20- to 100-micron-diameter particles have been constructed, along with (a) a device for introducing a preselected particle into the chamber and (b) a system for measuring the charge, size, and motion of the particle. One of the chambers contains two hemispheres and a central ring; in the other, the two electrodes are hyperboloidal. The latter chamber incorporates additional provisions for the precise control of the temperature and composition of the gas in the chamber. Measurements of the particle motion agree with theoretical calculations. (Author)
