Abstract
An apparatus for generating ions which can be operated by a low signal voltage. The apparatus includes, a first voltage source for applying to a first electrode a first voltage slightly less than a critical voltage for constant ion generation; and a second voltage source for applying to a second electrode a second voltage significantly less than the first voltage having such an amplitude that a total of the first and the second voltages exceeds the critical voltage such that the ion generation by the first electrode takes place only while the second voltage is being applied to the second electrode.
