Notes:
The wire ion plasma source (WIPS) is a device that can be utilized as a pulsed ion source for ion-induced secondary-emission electron guns. The pulsed discharges of the WIPS are usually ignited by applying over-voltages onto the wire anode using a thyratron. The shortness of lifetime peculiar to such gas filled switching devices is known to be a major problem when utilizing the WIPS as a high-repetition-rate pulsed ion source. In this article a completely new method for the ignition of the pulsed discharges on the WIPS is proposed. This method, named the built-in electrostatic trigger method, does not need an external gas switching device. The new method also gives rise to another advantage in the pulsed-discharge characteristics since it minimizes the series impedance in the discharge circuit. The feasibility of the method is confirmed experimentally. A few improvements are introduced so as to realize high-repetition-rate pulsed operations of the WIPS. © 1997 American Institute of Physics.
