A test apparatus utilizing a Phase Doppler Particle Analyzer was developed to non-intrusively determine charge on small particles. Optimum operating conditions for the system were determined using highly characterized silica spheres with an average particle diameter of 60{mu} in a dry N{sub 2} gas. The silica spheres were triboelectrically charged, and passed through a high intensity electric field. The charged particle trajectories, diameter, and number density were monitored using a two… CONTINUE READING
