1. A voltage-isolating apparatus comprising:
at least two passageways, wherein each passageway is a continuous tubular structure and wherein each passageway having two openings wherein each opening is configured to be connected to external components and capable of being sealed such that a low pressure environment can be sustained within each passageway; and
a first and a second magnet positioned along opposite and exterior surfaces of each of the passageways wherein the first and second magnets impose a magnetic field in a transverse direction with respect to a lengthwise axis of each of the passageways, the transverse magnetic field tending to reduce the potential energy of charged particles traveling through each of the passageways.
