负氢离子产生并包含在室温电子等离子体中，通过离解电子附着在退出的中性离子上。我们观察到，当双控管模式存在时，电子和离子的离心分离得到了强烈的增强。向外离子输运速率与二极管模式振幅成正比，并伴有二极管模式阻尼。这在理论上还没有被理解。
Negative hydrogen ions are produced and contained within a room-temperature electron plasma, by dissociative electron attachment onto exited neutrals. We observe a strongly enhanced centrifugal separation of electrons and ions when a diocotron mode is present. The outward ion transport rate is proportional to the diocotron mode amplitude, with concurrent diocotron mode damping. This is not yet understood theoretically.
