CA 1333407
A gas discharge apparatus includes a discharge chamber including a transparent dome portion and an electrode-including base portion, which together enclose an ionizable gas. A cup-shaped base member is affixed at its periphery to the edge of the base portion of the discharge chamber. A power supply and discharge excitation network is disposed within the interior of the base portion. The power supply and discharge network include a pair of terminals. An oscillator and associated step-up output transformer powered from the terminals is positioned between the terminals and the discharge chamber. A field shield including a conductive sheet member is positioned between the terminals and the discharge chamber. The field shield is adapted to be electrically coupled to the electrode so that discharge-supporting electric fields may be established in the discharge chamber between the electrode and through the dome portion of that chamber to an effective ground electrode exterior to the chamber.
