摘要:
A system for inhibiting the transport of contaminant particles with an ion beam includes an electric field generator (12, 14) for generating an electric field (28) relative to a path of travel (20) for the ion beam (16). A particle (66) located in the ion beam (16) and in a region of the electric field (28) is charged to a polarity according to the ion beam (16), so that the electric field (28) may urge the charged particle (66) out of the ion beam (16).

A system for inhibiting the transport of contaminant particles with an ion beam (16) includes a particle charging system (12) for charging particles within a region through which the ion beam travels. An electric field (50) is generated downstream relative to the charged region so as to urge charged particles away from a direction of travel (18) for the ion beam (16).
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.
