Abstract: A method of manufacturing a multipole device includes the steps of: (a) forming an intermediate device by assembling a plurality of components including a plurality of precursor multipole electrodes, wherein the plurality of precursor multipole electrodes in the assembled device extend along and are distributed around a central axis; (b) forming a multipole device from the intermediate device by machining the precursor multipole electrodes within the intermediate device to provide a plurality of multipole electrodes having a predetermined spatial relationship; wherein a first component of the multipole device that includes a multipole electrode is attached non-permanently to a second component of the multipole device, the first component including a first alignment formation, and the second component including a second alignment portion configured to engage with the first alignment formation on the first component so as to facilitate alignment of the first component and the second component when the first component and the second component are attached, thereby allowing the first component to be detached from and then reattached to the second component while retaining the predetermined spatial relationship between the plurality of multipole electrodes.
