摘要:
When small airborne conducting particles and fibrils strike a conducting surface with an electric charge distribution on it, they acquire charge and are repelled from the surface. If the conducting surface is connected to a power supply of constant potential, a charging pulse is observed as each particle or fibril makes contact with the surface. A collection of such charging pulses can be processed by a pulse height analyzer to yield information about the size and frequency of conducting airborne particles.
