EFFICIENT, SELF-LIMITING CORONA DEVICE FOR POSITIVE OR NEGATIVE CHARGING

摘要

ABSTRACT OF THE DISCLOSUREA miniaturized scorotron corona generator forcharging a receiver surface includes a thin wire or asawtooth coronode partially surrounded by a conductiveshield with a control screen attached to the shield.The control screen is closely spaced to the receiversurface such that fringing fields between the screen andreceiver surface contribute significantly both toefficient ion pumping and to potential leveling.
