1. A mass spectrometry system comprising:
an ion source that produces ions;
an enclosure connected to one or more vacuum pumps that provide vacuum or reduced pressure within the enclosure; and
an electrode assembly that guides the ions, the electrode assembly being located inside the enclosure, the electrode assembly including:
a plurality of first electrodes that are connected to one or more voltage sources, the plurality of first electrodes being flexibly, or rigidly or non-flexibly, attached to or connected to each other,
a plurality of first spacers that are electrically-insulating and are located between two adjacent first electrodes of the plurality of first electrodes, and the plurality of first spacers provide spacing between the two adjacent first electrodes,
a plurality of second electrodes that are connected to the one or more voltage sources, the plurality of second electrodes being flexibly, or rigidly or non-flexibly, attached to or connected to each other, and
a plurality of second spacers that are electrically-insulating and are located between two adjacent second electrodes of the plurality of second electrodes, and the plurality of second spacers provide spacing between the adjacent electrodes,
wherein the electrode assembly is flexibly connected or attached to the enclosure with a plurality of connectors or structures.
