Abstract: A support structure and electrode design geometry for a compact high voltage feedthrough, which is used in low-pressure gas discharge devices. The high voltage coaxial cable which applies voltages to the various electrodes within the discharge device is fed through an insulating structure and supported therein by means of field shaping electrodes. The space between the field shaping electrodes is filled with an electronegative gas. The electrodes insure that the electrical field lines merge smoothly from the low pressure region, across which high voltage is applied, into the dielectric of the coaxial cable. The structure minimizes local electrical stresses while maintaining a high voltage electrode separation in the low pressure region which is less than that at which Paschen breakdown occurs. The advantage of the present invention is its compactness of size and that it minimizes the probability of vacuum, surface, and bulk breakdown as well as Paschen breakdown.
