    摘要: A system (10) for inhibiting the transport of contaminant particles (60) with an ion beam (44) includes a pair of electrodes (14, 16) that provide opposite electric fields (26, 28, 30, 32) through which the ion beam (44) travels. A particle (60) entrained in the ion beam (44) is charged to a polarity matching the polarity of ion beam (44) when traveling through a first of the electric fields (26, 28). The downstream electrode (16) provides another electric field (30, 32) for repelling the positively charged particle (60) away from the direction of beam travel.
