Abstract
We have achieved electrostatic removal of micron-size particles adhering to conductive surfaces. Electric fields much greater than the breakdown field for air (30 kV/cm) are needed for removing particles having diameters of the order of microns (µm), so these measurements were done in vacuum. We have also measured the fraction of particles removed versus applied electric field. For spherical nickel particles, the field needed to remove 50% of the particles of a given size was approximately inversely proportional to particle size. Removal of 95% of the particles tested (nickel, SiO2, polystyrene latex) typically required about twice the field, about four times the force, that removal of 50% of the particles required.
