1. A lid for use in a mass spectrometry system, comprising:
a substrate comprising a plurality of electrically non-conductive layers coupled to one another, the substrate being configured for engaging with an opening of a vacuum chamber of the mass spectrometry system for sealing the chamber from an external environment such that one surface of the substrate is exposed to the vacuum chamber (“vacuum surface”) and an opposed surface of the substrate is exposed to the external environment (“external surface”),
one or more electrically conductive traces extending between the external surface and the vacuum surface and configured for providing electrical connections between one or more RF and/or DC sources disposed in the external environment and one or more components of the mass spectrometry system disposed within the vacuum chamber, and
at least one electrical contact element that is at least partially embedded in one or more of the plurality of layers, the at least one electrical contact element being accessible from the vacuum chamber, wherein the at least one electrical contact element is configured for mechanical mounting of at least one of the one or more components of the mass spectrometer system, and to provide an electrical connection to at least one of the one or more electrically conductive traces,
wherein a proximal end of the one or more electrically conductive traces is accessible to the external surface of the substrate and a distal end of each of the one or more electrically conductive traces is accessible to the vacuum surface of the substrate and wherein the proximal and distal ends are laterally displaced relative to one another.
