ABSTRACT:
A triggerable ceramic gas tube voltage breakdown device, particularly adapted for use in an electrical circuit for controlling the light output of a photoflash lamp, includes means for reducing the attenuation of an electrical trigger pulse in the region of the electrode gap due to the ceramic spacer tube. The electric field intensity in the region of the electrode gap resulting from the trigger pulse may be enhanced by disposing annular conductive material in the region and by connecting that material to a source of the trigger pulses. Alternatively or in conjunction therewith, the configuration of the ceramic spacer tube may be altered by removing material from the ceramic spacer tube in the region of the electrode gap, thereby enhancing the electric field intensity in that region resulting from the trigger pulses.
