ABSTRACT:
A miniaturized scorotron corona generator for charging a thin wire or a receiver surface includes a sawtooth coronode partially surrounded by a conductive shield with a control screen attached to the shield. The control screen is closely spaced to the receiver surface such that fringing fields between the screen and receiver surface contribute significantly both to efficient ion pumping and to potential leveling.
