Abstract
An apparatus for delivering ions between vacuum stages. The apparatus includes a concave electrode ion pipe originating in a first vacuum stage and terminating in a second vacuum stage. The design of the concave electrode ion pipe provides for transport of ions over long distances without substantial loss of the ions while at the same time restricting overall gas flow. The invention allows for the elimination of vacuum stages or a reduction in vacuum pumping speed(s) if the same number of vacuum stages is employed.
