    • A plasma system has a plug-in cartridge (20) having a pair of identical opposed electrode blocks (21, 22) each comprising a series of electrodes (23) in the form of ridges on one side (facing the ionisation path), and on the outside heat sink fins (24). There is a process gas inlet manifold (25). The path between the electrodes (23) outlets into a treatment conduit (26) having openings into catalytic converters (27, 29) through which waste gas is driven to atmosphere by fans (28, 30) respectively. Process gas such as air is drawn in a flow A into the manifold (25), and passes in a flow B along the path where it is ionised. Ionised air outlets into the treatment conduit (26) in a flow C where it impinges against the sample S being treated. Waste air flows (D) through the catalytic converters (27, 29) where ozone is converted to oxygen for safe discharge E to atmosphere. Each pair of opposed electrodes (23) is an ionisation stage in which a high voltage sine wave causes breakdown of the gas in the gaps between the electrodes. The output of the first stage contains some ions and a large number of excited species including metastables. Recombination occurs to some of the species while in transit to the second stage. The species arriving at the second stage cause seeding of the next discharge at that stage and a larger amount of species is created than produced by the first stage. This is because the collision frequency increases with increase in the number of ions, thus accelerating the production of further ions under an electric field. The process continues through each successive stage, yielding a much higher density of active species than would be produced by a single pair of electrodes with an equivalent surface area.
    • 等离子体系统具有插入式盒(20),该插入式盒(20)具有一对相同的相对的电极块(21,22),每一对包括在一侧(面向电离路径)的隆起形式的一系列电极(23),以及 在外部散热片(24)上。 有一个工艺气体入口歧管(25)。 电极(23)出口之间的路径到具有开口的处理导管(26)中,废气分别通过风扇(28,30)被驱动到大气中。 诸如空气的处理气体在流动A中被抽吸到歧管25中,并且沿着其被电离的路径通过流B。 电离空气出口流入处理管道(26),流体C撞击处理的样品S. 废气通过催化转化器(27,29)流动(D),其中臭氧转化为氧气以将其安全地排放到大气中。 每对相对电极(23)是电离阶段,其中高电压正弦波引起电极间隙中气体的破坏。 第一阶段的输出包含一些离子和大量激发物种,包括亚稳态。 一些物种在转运到第二阶段时发生重组。 到达第二阶段的物种在该阶段导致下一次排放的播种,并且产生比第一阶段产生的更多的物种。 这是因为碰撞频率随着离子数的增加而增加,从而加速了电场下的其它离子的产生。 该过程通过每个连续阶段继续,产生比由具有等效表面积的单对电极产生的活性物质高得多的密度。
